Initial Settings: Network Settings
I NITIAL S ETTINGS
This page contains instructions for configuring the Blue Coat Security Analytics Platform for the first time. To see how
to configure other settings, see Settings.
Network Settings
1. After you have logged in to the web interface (admin | Solera), accept the End User License Agreement.
2. The Initial Configuration page is displayed. If you cannot see the Initial Configuration page, append
/settings/initial_config to the appliance's IP address in the address line of your browser.
3. Optional — Specify a Hostname (system name) for the Security Analytics Platform appliance. The name typed
here is displayed as part of the prompt when anyone logs in to the command line on this appliance. You must
register this hostname with your DNS servers if you intend to refer to this appliance by its hostname.
4. Set the IP address, mask, and default gateway for the management gateway (eth0) using one of the following
methods:
•
Select the Use DHCP check box to automatically retrieve network settings. If you choose to enable DHCP, it
is recommended that you use the DHCP reservation feature of your DHCP server to statically map the MAC
address of the management interface to an IP address.
•
Specify the network settings manually.
If you set a temporary IP address on the CLI using sudo ifconfig, you must re-specify the IP
address, netmask, and gateway on this page; otherwise, the IP address will revert to the default
(192.168.20.20) next time you attempt to connect to the web interface.
5. Optional — Specify the IPv6 unicast address. For secondary addresses, separate the addresses with a space.
6. Optional — If your appliance accesses the Internet through a proxy, type the IP address of the proxy in the
following format: <ip_address>:<port>.
If your appliance accesses the Internet through an authenticated proxy, edit /etc/environment:
http_proxy="http://<username>:<password>@<IP_address>:<port>"
https_proxy="http://<username>:<password>@<IP_address>:<port>"
Also see how to install the proxy's SSL certificate.
7. Specify up to three DNS servers. If you will be using hostnames for other settings on this appliance, you must
specify the primary DNS.
8. Set the correct date and time for the appliance (MM/DD/YYYY hh:ii:ss). You can enable NTP later.
Because time is an essential parameter for both PCAP generation and playback, you must set the
correct time on the appliance before you begin to capture data.
9. If available — For Language, select a display language for the web interface.
10. Recommended — Change the root password for the appliance and specify its lifespan.

Updated 04 Apr 2016
Initial Settings
11. For Password, change any of the requirements, as desired.
12. Click Save.
•
If you changed the hostname, HTTP proxy settings, or time zone, the appliance will
automatically reboot.
•
If you changed the IP address, a message is displayed to confirm that the IP address is being
changed. You may need to log out and back in to re-establish a connection to the appliance.
Install the License
13. The License Details dialog is displayed.
14. Locate the license key that Blue Coat gave to you. Does your appliance have access to the Internet
(license.soleranetworks.com; port 443)?
Yes — Under Retrieve License,
input the License Key and click
Send Request.
• If applicable, select the
desired license type.
• The appliance sends the
license key and the license
seed file to the Solera
Networks license server,
which generates the
appropriate license file
(license.tgz) and returns it to
the appliance, which then
automatically reboots.
No — Click Download DS Seed to download the seed
file (dsseed.tgz) to your workstation.
• On a workstation that has Internet access, go to
license.soleranetworks.com.
• Type your license key, upload dsseed.tgz, click
Update.
• If applicable, select the desired license type and click
Update.
• Save the license file (license.tgz) to your workstation.
• Return to the License Details dialog.
• Click Browse and select license.tgz.
• The license is uploaded and the appliance
automatically reboots.
If you save a TGZ file for another Security Analytics Platform appliance to your workstation, and
your OS names it [filename](x).tgz, the appliance will still accept the file.
15. Once the system has rebooted, select Settings > About > License Details to verify that the items are correct.
16. Click Download to create an archive copy of the license file (solera-license.dat). Store this file in a safe location that
is not on the appliance.
17. Consult All Settings to further configure your system. If you are setting up a Central Manager Console, continue to
these instructions.

How the Security Analytics Platform Works
H OW THE S ECURITY A NALYTICS P LATFORM W ORKS
Implementation
In a typical deployment, the Security Analytics Platform receives mirrored traffic from a SPAN port or network tap.
The traffic enters the appliance through one or more Ethernet ports, also known as "capture interfaces."
Drive Configuration
All Security Analytics Platform devices (except the CMC) comprise three logical drives or arrays:
•
Capture — Where raw packet data is written
•
Indexing — Indexed metadata (Indexing DB)
•
System — A Red Hat° Fedora°-based operating system
The actual size and composition of the drives vary according to the hardware and the specific configuration of the
Security Analytics Platform deployment. For example, in a Security Analytics 10G Appliance, all three drives are RAID
arrays, whereas in a virtual machine, the drives may be logically separate entities on a conventional hard drive.

How the Security Analytics Platform Works
Packet Capture
The figure below shows how incoming packets are processed and analyzed by the Security Analytics Platform.
1
Mirrored packets arrive from the LAN through one or more NICs.
2
When traffic begins to arrive, the NIC requests a "slot," a 65-MB RAM "container” into which the
NIC loads incoming packets. Each packet receives a time-of-capture stamp and a sourceinterface indicator.
3
When the slot is full, the slot is written to the capture drive, and the NIC requests another slot.
4
The metadata (packet headers, capture timestamps, and interface identifiers) for the packets are
written to the index drive. Flows or "conversations" between hosts are identified during indexing.
Also see Data-Enrichment Process.
5
Artifacts (files), email messages, and IM conversations are extracted from the capture drive.
6
When PCAPs are downloaded, the packets are retrieved from the capture drive.
7
Reports, report widgets, the capture summary graph, and geolocation are generated from the
metadata on the index drive.

How the Security Analytics Platform Works
Writing the Slots
The capture drive is logically organized into "slots." As each packet is captured, it is written to a slot. Slots are
allocated to the interfaces in sequential order (0–N).
The figure above shows four NICs: eth2 through eth5.
colored
Packet written from that NIC
gray
Nothing written because another NIC has that slot
white
Capture inactive on that NIC
>
Start capture session
X
End capture session
eth2 starts its capture session first, so it is allocated slot 0. eth5 is allocated slot 1, eth3 is allocated slot 2, and eth4
receives slot 3. The faster or busier NICs are allocated slots more frequently than slower or less-busy NICs. In this
example, eth2 and eth5 are allocated more slots because they fill their slots more quickly than eth3 and eth4.
•
Each capture session creates a "slot chain" — a list of the slots that were used for that capture
session in the order in which they were filled.
•
In the figure above, eth2 created the slot chain 0-4-8-12-14-18-21-24-28, whereas eth3 created
slot chains 2-6-10 and 16-19-22-25.
•
Slots are interface-agnostic. After slot N is allocated, slot 0 will be allocated to the next NIC that
requests a slot, regardless of which NIC was allocated slot 0 in the previous cycle.
Select Statistics > Storage System to see slot and slot-chain data.

How the Security Analytics Platform Works
Data Overwriting
The figure below shows how packets are logically written to the capture and index drives. The full packets and their
corresponding index entries (metadata) are written simultaneously to the two drives: the red circles represent a
particular set of packets with its corresponding metadata.
1
Packets are written to the capture drive in slot order from 0–N.
2
The corresponding metadata is simultaneously written to the index.
The write process always starts at the first slot and runs continually to the last, which prevents the hard-drive heads
from engaging in excessive motion. It also enables extremely fast packet capture: up to 10 Gbps with the appropriate
system RAM and RAID arrays.
After the last slot is filled, the next captured packet is written to slot 0. When the capture drive overwrites the first slot,
the capture drive has "recycled." Select Statistics > Storage System to see the recycle count for your capture drive.
The interval between cycles depends on the amount of data being captured, the size of the packets being captured,
and the size of the capture drive.
3
The indicated packet data is overwritten as the capture drive recycles the first time.
4
The corresponding metadata is still available for reports.
In the figure above, the recycle count has been incremented by one because the capture drive has begun to
overwrite the first set of packets. Notice that the metadata for the first packets has not yet been overwritten, because
the index drive typically does not recycle as quickly as the capture drive. For this reason, report and geolocation data
is often available after the original packets have been overwritten.

5
The original packet data’s location is overwritten a second time.
6
The corresponding metadata has now been overwritten.
As the second cycle begins, the metadata for the original packets begins to be overwritten.
The web interface indicates whether the packets or metadata have been overwritten: View Data
Availability.
Overwriting Imported PCAPs
When you import a PCAP, the PCAP is first uploaded to system RAM and queued into slots in the same manner as the
data from the capture interfaces. The interface for an imported PCAP is designated as impt[x].
It is then written to the capture drive alongside the live data.
Because the capture drive overwrites slots according to slot order, not according to timestamps,
imported PCAPs will be overwritten according to their location on the capture drive, not according to
the "age" of the packets.
For example, if you are actively capturing data in 2014 and you import PCAPs from 2013 (and retain
the original timestamps), the capture drive will not overwrite all of the PCAPs from 2013 before
starting to overwrite the data from 2014; instead, it will overwrite the slots in numerical order, 0–N,
as usual.

Data-Enrichment Process
1
Captured packets and imported PCAPs are written to the capture and index drives.
2
Some flows match rules that are configured via data-enrichment actions and ThreatBLADE activation.
3
Files (artifacts) in the matching flows are reconstructed.
4
The files that are specified by the data enrichment file-types filter are forwarded to data enrichment.
5
The files are analyzed by the ThreatBLADES, Local File Analysis, and reputation, integration, and analysis
providers.
6
The results of the analyses are displayed in alerts and in ThreatBLADE-related reports and report widgets.

Data Capture
Capture-Interface Aggregation
In some cases it is advantageous to aggregate two or more physical interfaces into one virtual interface, e.g., if you
have separate physical interfaces for Rx and Tx traffic, an aggregated interface permits the system to match initiator
traffic with its corresponding responder traffic.
The following rules apply to interface aggregation:
•
You can aggregate as many interfaces as are on a single appliance.
•
You can add only one interface to the aggregate at a time.
•
If any of the component interfaces have a capture filter, that filter will be ignored in the aggregate.
•
You can apply a capture filter to the aggregated interface.
•
When you separate an aggregated interface, you separate all of the component interfaces; you cannot delete
only one or two interfaces from the aggregate.
•
After separating an aggregated interface, any filters that were on the individual interfaces will be reapplied,
whereas any filters on the aggregated interface will be removed.
To aggregate interfaces, follow these steps:
1. Stop capture and playback on all of the interfaces that you want to aggregate.
2. Click and drag one interface box onto another interface box.
3. Verify that you have selected the correct interfaces, make a note of the new interface name, and click Combine.
4. Click Start Capture to start capturing on the aggregated interface.
5. To separate the aggregated interface into its component interfaces, stop the capture or playback on the
interface.
6. Click the chain icon at the top-right of the interface box and click Separate.

Data Capture
Reprocessing
In some cases, when a data-enrichment action sends a query to an external source, or when a ThreatBLADE sends
a query to the Global Intelligence Network, there is no immediate response. In other cases, you may have altered
your favorites or actions, or report attributes may have been included in a newer version of the Security Analytics
Platform.
You can select data to be examined again by the data-enrichment process as well as reindexed.
•
Prior to version 7.1.3, reprocessing did not include reindexing. You might want to reprocess
data that was captured prior to version 7.1.3 so that any new report attributes can be indexed. It
is highly recommended that you reprocess pre-7.1.3 data for the new Heartbleed-detection
attributes.
•
For certain encrypted protocols such as SSH, IPSEC, and ISAKMP, the
tls_heartbeat_attack_attempt attribute will not be indexed during reprocessing. Heartbleed
detection is therefore dependent on the tls_heartbeat_mismatch attribute.
1. On Capture > Summary, select a timespan to reprocess.
2. Select Actions > Reprocess. The Reprocessing Jobs page is displayed.
3. Click New. The Time Range shows the same start and end times as you selected on the Capture Summary
page. You may change the time range, as desired.
4. Click Save. The selected data is sent back through the actions engine and is also indexed again.
5. The columns on the Reprocessing Jobs page are as follows:
•
Start Time — The starting time of the data to be reprocessed.
•
End time — The ending time of the data to be reprocessed.
•
Processing Start — The time that the reprocessing job starts.
•
Processing End — The time that the reprocessing job ends.
•
Command — The type of reprocessing job:
•
o
1 = Reindexing — Packets that were not indexed at time of capture are indexed.
o
2 = Reprocessing — Packets are run again through the indexing and data-enrichment processes.
Source — The origin of the job:
o
1 = Auto — When system resources prevent indexing at time of capture, resulting in classification
discards, the system uses its idle time to index that data.
o
2 = Manual — The reprocessing or reindexing job was initiated by the user:

Reprocessing is manually initiated as described in steps 1–4.

Reindexing is manually initiated on the Summary page status bar.
•
Percent Complete — Percentage of the job that is completed.
•
Actions — Click
to cancel the unfinished portion of the job. If the job is 100% complete, this will delete
the entry from the list.

•
Data Enrichment Jobs — Number of verdicts that have been returned to the Alerts page from the
ThreatBLADES, and reputation, analysis, and integration providers.
•
Created Time — The time at which the PCAP import began.
•
First Packet Time — The timestamp on the first packet in the PCAP file. If you selected Retain original
packet timestamps for the import, this date will be earlier than the Created Time; otherwise, it will be a few
seconds later.
•
Actions — Click an icon:
o
View Import Information — See more information about the import, including error messages.
o
View Alerts of This Import — Open the Alerts page to see only the alerts that this PCAP generated.
o
View This Import — Loads the PCAP into the Analyze > Summary view with import_id=[x] in the
filter bar.
Storage System Page
On the Statistics > Storage System page, an entry for the imported PCAP is displayed under Active Slot Chain for
Interface impt [X].
•
Because PCAPs are imported to the capture drive along with the live captures, imported PCAPs will be
overwritten as the capture process cycles.
•
As a PCAP is overwritten, the values that indicate size and location gradually decrease. The entry for the
PCAP disappears when the PCAP data in the capture drive is completely overwritten.
•
When you import multiple PCAPs via the same virtual interface, the system shows the combined statistics for
the PCAPs in a single entry.
Capture Summary Page
On the Capture > Summary page, click select View > PCAP Import to see the histogram for the PCAP.
•
If you selected the Retain original packet timestamps check box during import, the PCAP data will be
displayed in its original capture timeframe at the far left of the chart.
•
Any activity that the PCAP import generates — such as ThreatBLADE requests or classification discards —
is displayed using the actual timestamps. For example, if the original packet timestamps are in February and
the PCAP is imported two months later, the histogram for the PCAP import will be in February and the
ThreatBLADE requests it generates will be shown as occurring in April.
Analyze PCAP Files in Wireshark
•
To view PCAP files in Wireshark°, you must have downloaded and installed that third-party application.
•
Follow the Wireshark instructions to import and read PCAP(NG) files.
•

Use the dsregen command in the CLI for these functions. (Consult the
Security Analytics Platform Reference Guide on bto.bluecoat.com.)
Use the playback feature to reconstruct and transmit captured data flows to a physical network interface for analysis.
Depending on which data is selected for replay, the data is lifted from the capture drives or regenerated directly from
the input interface(s). Play back live data to forward data flows to a physical network interface for analysis. The Blue
Coat Security Analytics Appliance can regenerate traffic with less than 1 ms latency, even at high network speeds (up
to 10 Gbps).

Playback
Create a Playback Session
1. Select Capture > Summary.
2. For the output interface, click Start Playback.
3. Select the input interface(s) whose data you want to include.
4. Select the Output Interface to be used.
Interfaces that are in use for capture cannot be used as the output interfaces for playback;
otherwise, the existing capture sessions will be stopped.
5. For Time Span, select one of the following:
•
All Captured Data — Select to replay all of the data that is currently on the capture drives.
•
Live Data — Select to send the data that is currently being captured.
•
Custom Time Range — Select to specify the beginning and end.
o
For Start Time, expand the list to select a fixed timespan or specify manually the date and time.
o
Select Never End so that the data continues to play back until you stop it.
o
For End Time, expand the list to select a fixed timespan or specify manually the date and time.
6. For Speed, select the speed at which the data will exit the output interface.
When sending data from multiple input interfaces to a single output, take into consideration the
interface speeds. For example, if you have two 100-Mbps input interfaces and your output interface
is also 100 Mbps, you might experience problems with throughput.
7. To apply a filter to the output interface, expand the Filter list and do one of the following:
•
Select or edit an existing filter.
•
Select Create New Filter and specify a Name and the BPF Expression for the filter.
8. Click Save.
9. The message Playback in Progress is displayed on the interface box if the playback session is successful.
Click to see the parameters of the playback.

Playback
Many-to-Many Sessions
When a playback session is created, the system merges the input from the physical interfaces and maps it to a virtual
interface (imfX), which then forwards the traffic to another physical output interface.
The web interface permits you to specify many-to-one sessions, i.e., multiple input interfaces to a single output
interface. To create the equivalent of a many-to-many session, you must create one session per output interface.
example
In the example above, there are two output interfaces — eth6 and eth7 — so the following two sessions must be
created:
Session
Input
Filter
Output
1
eth2, eth3
[as desired]
eth6
2
eth2, eth3
[as desired]
eth7
CLI Commands for Many-to-Many Session
To set up the session for the mappings in the example, type the following commands. (For more information, see
dscapture map and dsregen in the Security Analytics Platform Reference Guide on bto.bluecoat.com):
dscapture --map ifm0 eth2
dscapture --map ifm0 eth3
dscapture --map ifm1 eth2
dscapture --map ifm1 eth3
dsregen start ifm0 eth6
dsregen start ifm1 eth7
To limit the session to a particular timespan — from 8:00 a.m. to 5:30 p.m. on April 25, 2013 — type the following
commands:
dscapture --map ifm0 eth2
dscapture --map ifm0 eth3
dscapture --map ifm1 eth2
dscapture --map ifm1 eth3
dscapture --settime ifm0 04.25.2013.08.00.00 04.25.2013.17.30.00.00
dscapture --settime ifm1 04.25.2013.08.00.00 04.25.2013.17.30.00.00
dsregen start ifm0 eth6
dsregen start ifm1 eth7

Data Availability
D ATA A VAILABILITY
Data availability is a function of the rate at which the capture and indexing drives overwrite existing data.
You can see data availability by expanding the timespan selector.
Data availability information is displayed:
•
[no message] — All metadata and packet data are available.
•
Limited packet data — Full metadata is available as well as some packet data.
•
No packet data — Full metadata is available but no packet data.
•
Limited data — Some metadata and packet data is available.
•
No data — All packets and metadata have been overwritten, or no data was captured during that time.
In some cases, just after packets have been captured but indexing has not been completed, the
data is temporarily not available for searches or reports.
Calendar Display
Click a date to see color-coded information for packet and metadata availability.
•
White background — All metadata and packet data are available. Reports, artifacts, and PCAP downloads
are available for this data.
•
Light pink background — Metadata is available but the corresponding packets have been overwritten. Only
reports are available for this data.
•
Dark pink background — All packet data and metadata have been overwritten, or no data was captured on
those days.

Data Availability
Capture Summary Graph
The capture summary graph (Capture > Summary) indicates overwritten data with the light pink Packet data
overwritten (metadata only) area and dark pink No data available area.
Capture summary data can remain available after the corresponding packets and metadata have
been overwritten because it is not stored on the capture or index drives. See Drive Space
Management for information on retaining and deleting capture summary data.

Reindexing
During periods of heavy network activity, the system may not be able to index every packet as it is written to the capture
drive. During periods of lower activity, the system returns to the unindexed packets on the capture drive and
attempts to finish indexing them.
On the Status bar, the total amount of data in the flows is indicated. If the system has not been able to finish indexing
all of the packets, the
icon is displayed. Click the icon to see how many flows remain to be indexed.

Primary Filter Attributes
P RIMARY F ILTER A TTRIBUTES
Valid primary filter attributes are as follows. Consult Report Attributes in the Security Analytics Platform Reference
Guide on bto.bluecoat.com to see which data is the source for each attribute. Also see Advanced-Filter Attributes.
•
Initiator/Responder Fields — During session-based filtering, the field that provides the value for these
attributes depends on the host’s role in a TCP conversation: the host that sends the first SYN packet is the
initiator and the host that sends the corresponding SYN+ACK packet is the responder. During packet-based
filtering, the initiator value is always from the source field and the responder value is always from the destination
field.
•
Length and Number Parameters — For some attributes, you can specify number or length. num(<attribute>)
returns the flows that contain the specified number of the attribute; len(<attribute>) returns the attribute with the
specified length. For example, len(filename)=6 returns all of the flows that contain a six-character filename,
whereas num(filename)=6 returns all of the flows that contain six instances of the filename attribute.
•
•
When the system detects matching traffic for a filter, it returns the entire flow that contains
matching data, which may include data that do not match the favorite. For example, if the filter
is len(filename)=10, the system will return all of the data from every flow that contains a file
name with 10 characters. Some of those flows may include filenames that do not have exactly
10 characters.
•
Regular expressions are not valid for the len(<attribute>) and num(<attribute>) parameters.
Hash Searches — When using the md5_hash and sha1_hash attributes, the match must be exact to produce
a result, but for fuzzy_hash you can specify how much of the hash must match.
o
Command Line Interface — /fuzzy_hash/_ge_abc123eae%2570/ will find fuzzy hashes that have a
70% or higher match. To specify a range — for example, between 70–80% — type
/fuzzy_hash/_ge_abc123eae%2570_and_le_abc123eae%2580/. Note that the percent sign must be
URL-encoded as %25.
•
Encrypted Heartbleed Attacks — If a "Heartbleed" attack is contained within an encrypted heartbeat
message, the tls_heartbeat_attack_attempt attribute cannot detect it; however, a successful attempt will be
detected by tls_heartbeat_mismatch.
•
Namespaces — The Namespace column indicates the namespace to which the attribute belongs.
o
A Summary view that contains report widgets from different namespaces will take longer to complete.
o
When creating advanced queries for an API, attributes from different namespaces cannot be placed in
the same advanced-query array.

W ILDCARDS AND L OGICAL O PERATORS
Wildcard Usage
Favorites and filters support two regular-expression characters: the question mark (?) and the asterisk (*):
? = single character
* = zero or more characters
These wildcard expressions may be used in the filter bar and for favorites. (The advanced filters use other conventions.)

Wildcards and Logical Operators
Logical Operators in Primary Filters
Complex filters can be created by combining multiple filters in the filter path. Filters are applied from left to right, such
that the first value on the left is filtered first and each filter is applied afterward, in order. For example, for the filter
the data is filtered first on the application_id value and then on the ipv4_initator value, which results in all entries where
the application is HTTP and the initiator IP is not 10.10.2.123.
Operation
Syntax
Example
Result
AND

Wildcards and Logical Operators
•
OR is operational only with the same attribute types, e.g., two application_id filters or multiple port filters. If the
attribute types are different, the operation is always AND.
•
To apply a primary filter to a different view (Summary, Reports, Extractions, Geolocation), select the view
while the filter is still present in the filter bar.
•
To save a primary filter, click the star
•
To delete an individual filter, click its white
•
To delete everything in the filter bar, click
•
To modify an attribute/value pair, click it to enter edit mode, type the new value, and press Enter.
•
Applying a primary filter causes an operation, e.g., extraction, to be performed again, whereas advanced filters
are applied only to the data already in the view.
to add it to the favorites list.
and click Update or press Enter.
and click Update or press Enter.
Logical Operators in Advanced Filters
•
NOT (does not equal) is treated as a negative AND. When there are multiple NOTs in the filter, they are treated
as a single AND operator.
•
Any special character between double quotes is treated as plain text, e.g., the asterisk in "A*C" is treated
as plain text, whereas in A*C it is a wildcard.
•
The term null is valid for the = and != operators, e.g., referer!=null will return all entries where the referer
field contains a value.

Favorites
Format a List of Favorites
You can import a list of values for a single filter attribute. Importing a list of values in this manner automatically creates
the favorite as attribute=value. The list delimiter determines the boolean operator.
Delimiter
Example Text File
Favorite(s) Created
network service
attribute="network management, file server, file transfer,
network service"
192.168.*.*, 10.0.0.0_8, 172.16.0.0/12

attribute="\"solera\""
Comma (AND) network management, file server, file transfer,
Line Break
(OR)
•
The system will automatically escape double quotation marks, backslashes, and other nonwildcard characters.

JSON Formatting for Favorites
•
Define the favorites to import using JSON. The file should be UTF-8 encoded without BOM.
•
Imported favorites that have the name of an existing favorite will be renamed <Favorite> 2.
•
Valid values for attribute and value come from the primary filter.
•
Valid values for <operator> are equals (=), not equals (!=), less than (<), less than or equals (<=), greater than
(>), greater than or equals (=>), contains (~), not contains (!~). Format single-level favorites as follows:
{
"favorite_name_1":
[
"attribute_1<operator>value_1",
"attribute_2<operator>value_2"
],
"favorite_name_2":
[
"attribute_3<operator>value_3",
"attribute_4<operator>value_4"
]
}
Nested JSON Favorites
To nest favorites, the lowest-level favorites must be defined first in the file, followed by the "container" favorite. The
container cannot reference favorites that already exist on the appliance. The following example creates four favorites:
three "subfavorites" and one "container" that includes the subfavorites.
{
"subfavorite_1":
[
"attribute_1<operator>value_1"
],
"subfavorite_2":
[
"attribute_2<operator>value_2"
],
"subfavorite_3":
[
"attribute_3<operator>value_3"
]
"CONTAINER_FAVORITE":
[
"favorite=subfavorite_1", "favorite=subfavorite_2",
"favorite=subfavorite_3"
]

Reindexing
R EINDEXING
During periods of heavy network activity, the system may not be able to index every packet as it is written to the capture
drive. During periods of lower activity, the system returns to the unindexed packets on the capture drive and
attempts to finish indexing them.
On the Status bar, the total amount of data in the flows is indicated. If the system has not been able to finish indexing
all of the packets, the
icon is displayed. Click the icon to see how many flows remain to be indexed.
Click Give Priority to This Timespan to move the unindexed flows in the current view to the top of the reindexing
queue.
On Capture > Summary, select View > Classification Discards to see the rate at which packets are not immediately
indexed.

Geolocation
G EOLOCATION
The Blue Coat Security Analytics Platform provides "geolocation," which is a representation of a host location on a
world map.
Select Analyze > Summary > Geolocation to view the geolocation report.
The Report Summary panel displays a geographic representation of the filtered data. By default, the map is centered
on the Greenwich meridian at the equator (0 lat, 0 long).
The geographic location of every IP address is identified by a dot on the map. The size of the dot indicates amount of
data transferred to or from that geographical area, and the saturation of the color indicates the concentration of
markers, i.e., darker dots indicate that, upon zooming in on that location, you will see multiple markers.
A large dot in the ocean beside Western Africa (0 lat, 0 long) is the marker for those IP addresses whose geographic
location cannot be determined.
Geolocation can locate only IP addresses that have location information in the MaxMind databases.
Map Navigation
Use the controls in the upper-left corner to zoom and center the map.
Press Shift and drag your cursor to select
a specific area of the map to enlarge. The
results will change to list only the results
that are in the view.
To return to the full view, click the globe

Notes on the Accuracy of Geolocation Data
•
Geolocation can identify only the server location, not a specific device.
•
Routing randomization with services such as Tor° or Onion may produce unreliable geolocation data.
•
IP addresses can be spoofed with readily available technology.
Geolocation Settings
Select Settings > Geolocation to open the Geolocation page. On this page you can view and specify values used
when examining the geographic location of connections. These include internal subnets, Google Earth country
colors, and MaxMind city databases.
Internal Subnets
Use the Internal Subnets controls to specify the geographic location of an internal subnet (or multiple subnets). This
marks all the traffic on that subnet as occurring at a single location.
By definition, internal subnets do not have an externally knowable geographic location and by default are located at
0 latitude, 0 longitude (this places them in the Atlantic Ocean, slightly south and west of Nigeria). Use the Internal
Subnets feature to specify where your subnets are located on the world map.
example
A company has offices in New York, Vancouver, and Tokyo. Their network IPs are 10.1.0.0/16 for New York, 10.2.0.0/16
for Vancouver, and 10.3.0.0/16 for Tokyo. Without setting the internal subnet values, they would all appear at 0,0 on the
map. With the Internal Subnets feature, the subnets appear in their proper locations.

Geolocation
Specify Geographic Locations for Internal Subnets
1. Select Settings > Geolocation.
2. Under Internal Subnets, select the Enable Internal Subnets check box.
3. Type the IP address for the subnet using a CIDR notation that includes zeroes, e.g., 192.168.0.0/16.
4. Type the latitude and longitude for the subnet.
5. Type a label for the subnet.
The label that you specify can be anything you want; it will be displayed in the data table and when
users place their cursors over the dot on the map.
6. To specify additional internal subnets, click add a new subnet.
Geolocation Filters
The Advanced Filter control in the Results panel allows you to easily and rapidly apply additional filtering to the report
data.
To apply an advanced filter, click the Add a Filter box and select the filter term you want to use. To apply a primary
filter, follow these steps:
1. Select Analyze > Summary > Geolocation.
2. In the Results panel, under Location, click the city name that you want to look at. The item expands, displaying a
list of the IP addresses associated with that geographic location.
3. Click the IP address to examine.
4. For each IP address to add as a filter, click Add to Filter Bar > As [attribute] > [Equals | Not Equals]. The filter
is added to the filter bar.
•
If you click Add to Filter Bar only, the filter ipv4_address="x.x.x.x" is added to the filter bar.
5. When you have finished adding filters, click Update.

By default, the Packet Analyzer will load only the first 1000 packets of the specified PCAP. As you scroll down to
packet number 1001, Packet Analyzer will automatically load the next 1000 packets onto the screen. (For reference,
the PCAP path is displayed at the top of the window.) It is recommended that you not load more than 10,000
packets to avoid performance degradation.

change the columns, the sort order, or the colors. The default columns show the following data:
No. The number of the packet in the capture file. This number will not change even when a filter is used.
Time The timestamp of the packet. The presentation format of this timestamp cannot be changed.
Source The IP address of the packet’s origin
Src Port The port of the packet’s origin
Destination The IP address of the packet’s destination
Dst Port The port of the packet’s destination
Protocol The protocol name in a short (perhaps abbreviated) version
Info Additional information about the packet content
Packet Details
The Packet Details pane shows the selected packet in a detailed form that explicitly identifies the packet’s protocols.
Click a protocol to see details.
The following two protocol fields are displayed in a particular manner:
•
Generated fields — The packet analyzer generates additional protocol fields that are enclosed
by brackets. The information in these fields is derived from the known context to other packets
in the capture file. For example, if the Packet Analyzer is doing a sequence/acknowledge
analysis of a TCP stream, these will be displayed in the [SEQ/ACK analysis] fields of the TCP
protocol.
•
Links — If the Packet Analyzer detects a relationship to another packet in the capture file, it will
generate a link to that packet. Links are blue and underlined.
Packet Bytes
The Packet Bytes pane shows the data of the selected packet in a standard hex-dump style. As is usual for a hex
dump, the left column shows the offset, the middle columns show the data in hexadecimal, and the right column
shows the corresponding ASCII characters.

The BlackBox Recorder is a Blue Coat Security Analytics Appliance that functions similarly to a black-box recorder on
an airliner: it quietly captures all network events until a security incident requires that you "break the glass" to view its
contents.
When the BlackBox Recorder is in "lights-out" mode, you have access only to the controls that permit capture and

Extractions
E XTRACTIONS
The Blue Coat Security Analytics Platform extracts and reconstructs many file types so that you can see accurate
copies of the images, web pages, and documents that have been transported across your LAN.
•
Prior versions of the Security Analytics Platform used signature-based extraction to produce
artifacts. Beginning in version 7.1, extraction is protocol-based.
•
With version 7.1.6, Security Analytics Platform can extract artifacts from unknown protocols
(application_id=unknown) but only as long as signature-based extraction is enabled to run in
parallel with protocol-based extraction. As a result, signature-based extraction (on Settings >
System) is now enabled by default.
Artifacts are now extracted from the following protocols:
•
HTTP

MIME-Type Display
You can specify which method determines the file type of an artifact: Select [Account Name] > Preferences:
•
Artifact MIME-Type Display — Specify the method for the extractor to determine the file type:
o
MIME — Use the value in the Content-Type field of the HTTP or email header, else return unknown.
o
Magic — Use the embedded magic number or file signature, else return unknown.
o
Derived — If both MIME and magic values are present, use internal logic to determine the most likely file
type.
Artifacts
Artifacts are objects such as Microsoft Word files, executables, and web pages. Extraction is performed automatically
as part of the capture operation, and the results are visible on the Extractions pages.
When an artifact is transferred via HTTP or email, the MIME type is specified in the header ("presented" in system
nomenclature). If it differs from the file type that the system "detects," using the magic number or file signature, the
value in the Type column is shown in red text. You can also use the file_type_mismatch attribute in the advanced filter to
find all such artifacts.

Data Enrichment
D ATA E NRICHMENT
Use data enrichment (also called "real-time extraction" or "micro-extraction") to send selected artifacts and data flows
to external sources for analysis. Among the external resources are:
•
Blue Coat ThreatBLADES
•
Analysis Providers
•
Reputation Providers
•
Integration Providers
Also see Data-Enrichment Process.
Query Types
The Security Analytics Platform supports two kinds of reputation query:
•
On Demand — On-demand queries are performed when the user views information from the reputation providers.
•
Data-Enrichment Action — The user creates a data-enrichment action, wherein matching traffic is
automatically sent to one or more enrichment providers.
Activate a Data-Enrichment Resource
Data-enrichment resources must be licensed before they can be activated. Contact Security Analytics Support to
purchase a Blue Coat ThreatBLADE or Malware Analysis Appliance subscription. The Third Party On-Demand
Reputation Providers are licensed by default; licenses for the Third Party On-Demand Integration Providers are the
responsibility of the user.
1. Select Settings > Data Enrichment.
2. In the Actions column, click a deactivated icon
to activate that resource.
Create a New Data-Enrichment Action
1. Select Analyze > Actions.
2. Click New. The New Action dialog box is displayed.
•
Name — Type a name for the data-enrichment action.
•
Favorites — Type the name of one or more existing favorites, or create a new favorite.
•
Type — Select Data Enrichment.
•
Send to — Select one or more data-enrichment resources. The options for this field are derived from the
items on the Data Enrichment Settings page.
•
You can select a resource that is not active or licensed, but the action will not produce a result
until the resource is activated.
•
For data-enrichment actions, the importance level (critical, warning, notice) will be determined
by the score that the resource provides.

3. Click Save.
•
When using data enrichment, it is recommended that you create capture filters for all capture
interfaces to exclude traffic to or from eth0, i.e., (!ifname eth0); otherwise, you will capture
duplicate traffic as the artifact is exported from the Security Analytics Platform appliance to the
external resource.
•
Consult Security Analytics Platform Ports and Protocols to configure your network firewalls for
data-enrichment traffic.
Exclude from Lookup
You can specify IP addresses and domains to exclude from lookup under Settings > Data Enrichment > Exclude
from Lookup.
This setting applies only to providers that evaluate URLs, such as WebThreat BLADE URL and
VirusTotal URL.
•
For IP Subnets, type those IP addresses that you want to exclude. Use CIDR notation without zeros, e.g.,
specify 127.0.0.0/8 as 127/8.
•
For Internal Domains, type domain names to exclude. Use the asterisk (*) as a wildcard, as needed.
•
Type each entry on its own line.

Samples that are submitted to multiple MAA/profile pairs are processed according to the following
rules:
•
A sample is sent one time to the MAA, where it is processed in a separate task for each profile.
•
For samples sent in parallel, Security Analytics sends the sample to the SandBox first (provided
that the SandBox supports the file type); if the results indicate a suspicious sample, the sample
is sent to the iVM profile(s). This measure prevents filling the iVM queues with innocuous
samples.
•
As soon as one profile returns a significant result, that result is returned to Security Analytics
instead of waiting for all profiles to complete before sending a verdict.
•
The MAA automatically routes mobile samples (Android APK) to the MobileVM, regardless of
which profiles are configured on Security Analytics.
•
To see the health of the MAA connection, open the System Utilization window.
Green means that the connection is active.

YARA Rules
YARA rules (version 3.2.0) can help detect live exploits before the URI is known to the Blue Coat Global Intelligence
Network. YARA rule hits are displayed as alerts on the Analyze > Alerts pages (when the score is 6 or higher) and in
the reputation information for individual artifacts.
Activate YARA Rules
Follow these steps:
1. Select Settings > Data Enrichment.
2. Activate the WebThreat BLADE and Local File Analysis.
3. Under Data Enrichment Mode, select the YARA check box.
4. Select Analyze > Actions and enable the Local File Analysis - Live Exploits action.
The Live Exploits Favorite
The Local File Analysis - Live Exploits favorite, which is used by the Local File Analysis - Live Exploits action,
specifies multiple mime_type=[x] values and then specifies uri_category="Unrated". That uri_category filter is included to
prevent overloading the YARA rules. With the WebThreat BLADE activated, files from known-malicious web sites are
tagged with uri_category=[WebPulse Category] and so are excluded by the Local File Analysis - Live Exploits favorite. In
this way the YARA rules are applied only to files from unknown web sites.
Customize YARA Rules
You can customize your YARA rules by following these steps:
1. Open the YARA rules file: /usr/lib64/python3.3/site-packages/derp/providers/third_party/yara_rules/rules.yar
2. Add, delete, or modify YARA rules, as desired. Keep in mind that YARA-rule analysis can be resource-intensive. If
a rule takes longer than two seconds to process, the analysis will be terminated. Consult YARA Tuning Options,
below, to change this interval.
3. Save the file. The new rules are available immediately. To test the new rule(s), open the Extractions page, expand
an artifact entry, and then click Reputation.

requests. If you find that too many tasks are being dropped, you
can increase the queue size to store more tasks. Keep in mind
that a larger queue size requires additional memory.

Endpoint Providers
E NDPOINT P ROVIDERS
The Security Analytics Platform can provide endpoint information to external endpoint-analysis providers such as
EnCase° Cybersecurity by Guidance° Software. Using a Security Analytics Web API, endpoint analysis providers
retrieve source and destination IPs, source and destination ports, and the timespan for selected alerts. With this
information, the provider can conduct its own endpoint investigations.
It is the responsibility of the user to license and install third-party endpoint analysis solutions.
Endpoint analysis support can be enabled as follows:

Login Correlation Service
L OGIN C ORRELATION S ERVICE
If you have already installed the Login Correlation Service prior to version 7.1, go to Settings > Data
Enrichment to download and install the latest version.
The Login Correlation Service for Microsoft° Active Directory° associates network activity with Microsoft AD domain
users. The LCS sends the following information to the Security Analytics Platform:
•
Username
•
IP address (as found in the domain server's DHCP log)
•
Login time
•
Authentication method
How the LCS Works
The LCS has two components:
•
LCS agent — Detects user logons and logoffs and creates an IP-to-username correlation. Resides on a DC,
server, or a workstation.
•
adlistener-d — A Linux daemon that adds the correlation information to the Indexing DB, from which the
User Name report is generated. Resides on the Security Analytics Platform.
The LCS agent parses the logon/logoff events of a DC's security logs. Specifically, it monitors the logs for these event
IDs:
•
4624 — An account was successfully logged on.
•
4634 — An account was logged off. After detecting this event ID, the LCS agent sends a WMI query to the
workstation to verify whether the user has actually logged off.
The LCS agent extracts the following information from those events:
•
User Name
•
Logon Type
•
Source Port
•
Domain
•
Workstation Name
•
Time
•
Logon ID
•
Source Network Address
•
Date
The LCS agent correlates User Name with Source Network Address and sends the pairings to adlistener-d over port 8843,
which adds the information to the Indexing DB.
Requirements
•
.NET Framework 3.5 or later
•
Windows Server 2008 DC (Windows Server 2012 is not supported)

Login Correlation Service
Configure the DC
For every Active Directory DC, that you want to monitor for logon events, perform these steps:
Configure the Advanced Audit Policy Setting
User logon information is stored in security logs on the DC. The LCS derives its information from these logs. To
capture logon events, the DC’s advanced audit policy must be configured to audit successful logon and logoff
events.
To configure an advanced domain login audit policy setting, follow these steps:
1. Log on to the DC as a member of the local administrators group.
2. Select Start > Administrative Tools > Group Policy Management.
3. In the console tree, double-click your forest, e.g., Forest: soleranetworks.com.
4. Double-click Domains, and then double-click the DC, e.g., solera.com.
5. Right-click Default Domain Policy, and then click Edit.
6. Open the following items in this order:
a.
Computer Configuration
f.
Configuration
b. Policies
g. System Audit Policies
c.
h. Logon/Logoff
Windows Settings
d. Security Settings
e.
i.
Logon
Advanced Audit Policy
7. Select the Configure the following audit events check box, select the Success check box, and then click OK.
8. Set Logoff to Success as well.
Configure the Group Policy to Enable WMI Access to a Remote Machine
•
The LCS uses remote WMI queries to verify whether a domain user is logged off. If a domain
workstation does not respond to a WMI query, then the LCS regards the user as not logged off.
•
If the user does not log off gracefully, Windows does not generate an event log; therefore, the
LCS does not detect the event. This missed event can sometimes be inferred when a user logs
on later to a workstation with the same IP address.
1. Select Administrative Tools > Group Policy Management > Group Policy Objects > Default Domain Policy.
2. In both the standard and domain profiles, select Computer Configuration > Administrative Templates >
Network > Network Connections > Windows Firewall and enable the Allow inbound remote administration
exception.

•
Only one LCS agent is required per domain.
•
You may install the LCS agent on the DC, on a Windows workstation in the domain, on a server
that is not in the domain, or on a server that is in the domain. The last option is recommended.
•
If you install the LCS agent on a Windows workstation, the workstation must be in the same
domain as the controller that you want to monitor, and it must always be connected to the
network. It is not recommended that the LCS agent be installed on a portable workstation.

Appliance Security
A PPLIANCE S ECURITY
LDAP Authentication
Because each network is unique, we cannot make specific recommendations as to how you should
integrate LDAP with your Blue Coat Security Analytics Platform.
When a user attempts to authenticate via LDAP, the process is as follows:
1. The user logs in via HTTP or SSH.
2. The appliance sends a BIND request containing the BIND DN credentials to the LDAP server.
3. The LDAP server returns success or failure.
4. The appliance sends the LDAP user credentials and search base criteria to the LDAP server.
5. The LDAP server returns success or failure.
6. The appliance allows authentication; if successful, the user is added to the user list on the Users and Groups
settings page.
With the LDAP authentication service, users can log on to the Security Analytics Platform using a
username/password combination stored on an external LDAP server. These credentials are valid for both the web
interface and the CLI.
Enable LDAP
1. Select Settings > Authentication.
2. Select the Enable LDAP Authentication check box. The system will automatically attempt to discover an LDAP
server.
3. If the auto-discover is unsuccessful, the LDAP Auto-Discover dialog box is displayed. Do one of two things:
•
Click Cancel and manually specify the LDAP settings.
•
Supply the BIND domain FQDN and click Save. Follow any other prompts to provide the LDAP BIND
authentication credentials for the domain controller. The system then discovers the configuration information
from Active Directory or the LDAP server and populates the LDAP Service page.
At any time during LDAP configuration, you can click the Test LDAP button to see if the settings are
valid.

Appliance Security
Modify LDAP Server Settings
If there is more than one domain controller on the system, by default the system discovers the primary server
configured. You can change the settings to use another domain controller by following these steps:
1. Select Settings > Authentication.
2. For Server, type the LDAP server’s hostname or IP address.
3. For Port, type one of the following:
•
389 for LDAP
•
3268 for Active Directory°
4. Select the Encryption Type.
•
For TLS or SSL, you should select the Verify Server Certificate check box only if your LDAP server has a
certificate from a valid certificate authority.
•
If the LDAP server certificates are self-signed, clear the Verify Server Certificate check box.
5. Enter the BIND DN and BIND Password for an account that has rights to search the containers where the LDAP
users are located. If your LDAP server does not require an authorized login, then you may leave the
Authenticated BIND fields blank.
6. Click Save. The appliance will immediately try to connect to the LDAP server.
Limiting LDAP User Searches
To improve LDAP login performance, you can constrain the range of containers to be searched when looking for an
LDAP user.
Search base
The starting container where the LDAP server will begin searching for LDAP users. Only one search base is allowed.
Specify using LDIF, e.g., DC=<subdomain>,DC=<domain>.
Scope
How the LDAP server will search within that container.
•
base — Queries only the search base but nothing below it
•
one — Queries only the first level under the search base but not the search base itself
•
sub — Queries the search base and every level under it

Appliance Security
Group DN
The group that is authorized to authenticate to the Security Analytics Platform. Only members of the specified group
will be able to authenticate to the appliance. Examples of the group members that are included in the search
parameters are displayed. The Group DNs are valid entries for the LDAP Groups field when creating a user group.
If the Group DN field is left blank, all users in the search scope will be able to authenticate, which
may pose a security risk.
You must correctly set the group membership attribute under Schema Configuration, because this
attribute’s syntax varies depending on the LDAP implementation used. If the attribute is incorrect, it
will not return the proper group membership information for authentication.
Identifying the LDAP Schema Configuration
Because LDAP schema mappings vary between LDAP implementations, you can select an appropriate schema
mapping such as InetOrgPerson, Microsoft° Active Directory°, and Microsoft Services for Unix°. Select the LDAP schema that
your server uses from the list. Most Open LDAP implementations will work with the InetOrgPerson configuration. If your
server’s schema is not in the list, select User Defined and fill out the resulting fields.
Note on Server-Side Changes to LDAP
Depending on the LDAP server being used, schema may need to be extended to allow for certain attributes such as

Kerberos° Authentication
If Kerberos is implemented on your network, you can provide single sign-on (SSO) access to the Security Analytics
Platform.
Kerberos SSO and Active Directory authentication via an LDAP group DN are mutually exclusive. If
Kerberos is enabled, anyone in the domain can authenticate to the Security Analytics Platform
appliance successfully. If you specify a group DN in the Searches section, Kerberos authentication
will be automatically disabled.
LDAP Server Setup
Install and configure the Active Directory or LDAP server. Consult the LDAP vendor's documentation for instructions.

Appliance Security
•
For Firefox°, go to the about:config page and modify the network.negotiate-auth.trusted-uris setting to include the
FQDN of the appliance.
•
For IE, go to Internet Options > Local Intranet, and add the FQDN of the Security Analytics Appliance as a
local intranet site. (If you are using the Windows short name, you do not need to perform this step.)
3. Configure the browser to negotiate with Kerberos instead of NTLM (NT LAN Manager).
4. Users must navigate to the domain name of the Security Analytics Appliance instead of its IP address. This
domain name can be the Windows short name or the FQDN. (The FQDN is recommended, because that is the
name in the certificate for HTTPS management.)
RADIUS Authentication
You can configure the Security Analytics Platform to accept RADIUS authentication.
1. Select Settings > Authentication.
2. Select the Enable RADIUS Authentication check box.
3. Fill in the fields as follows:

Two-Factor Authentication
2FA requires a token in addition to the username and password to access the web interface. The authentication
token is created by the Google Authenticator° mobile app, which is available for the following smart phones:
•
Android° 2.1 or later
•
BlackBerry° OS 4.5–6.0
•
iPhone° iOS 3.1.3 or later
Do not enable 2FA until after you have verified the following; otherwise, you may be locked out of
the web interface*:
• Google Authenticator is installed on your smart phone and is working.
•
The time on the Security Analytics appliance is correct and coordinated with NTP. Because the
2FA token is valid for only 30 seconds, the appliance will reject a token that appears to be
outside the validity timespan.
*Use the scm tally command to restore access.
1. Go to Install Google Authenticator at the Google° Accounts Help Center web page and follow the instructions to
install the application on your smart phone.
2. On the web interface, select [Account Name] > Preferences.
3. Select the Enable Google Authenticator check box.
4. Enter the secret key to Google Authenticator in one of two ways:
•
Scan the QR code.
•
Type the case-sensitive secret key into the space provided.
5. Click Save. 2FA is now enabled for this user account.
2FA is enabled per user account, not per appliance; therefore, some user accounts on the same
appliance can require 2FA to log in while others do not.
2FA Logins
When logging in to the web interface with a 2FA-enabled account, follow these steps:
1. Type the username and password as usual and click Log In.
2. A second login prompt is displayed. Type the authentication token as provided by Google Authenticator and click
Log In.
The authentication token changes about every 30 seconds, so you must consult Google
Authenticator for each login instance.

SSL Certificates and Keys
SSL C ERTIFICATES AND K EYS
You may install a certificate for the Blue Coat Security Analytics Platform or require that browsers have a certificate to
access the web interface. A self-signed certificate and key is automatically included on the appliance with the
Security Analytics Platform installation.
Install from the Web Interface
1. Select Settings > Security and scroll down to PKI and SSL.
2. The default certificate for the appliance, its common name, fingerprint, and date modified are displayed. The
name of the default private key is also displayed. Click edit
to upload a new certificate or key.
To generate a new certificate and key for the appliance, go to Generate a New Certificate and Key.
3. To require that browsers have a certificate to access the web interface, select the Require Client Certificate to
Access Web Interface check box.
When you enable this feature, all web browsers that do not have a valid certificate from the Issuing
Authority — including yours — will be prevented from accessing the web interface.
•
Upload the certificate that validates client certificates to Issuing Authority's Certificate.
•
Specify the URL of the certificate revocation list.
Certificates for CMCs and Sensors
If you have a CMC, you may set up one of the following scenarios:
•
All sensors present a certificate to the CMCs
•
All CMCs present a certificate to the sensors
•
Both the CMCs and the sensors present certificates to each other
1. On the appliance that requires the certificate (server role), do the following:
•
Select Require Client Certificate to Access Web Interface.
•
Upload the certificate that validates client certificates to Issuing Authority's Certificate.
•
Specify the URL of the certificate revocation list (PEM, DER, or CRL format).

SSL Certificates and Keys
2. On the appliance that is required to present a certificate (client role), do the following:
•
Select Use Appliance Certificate and Key to use the credentials that you uploaded in Step 2. This option is
valid only if the appliance certificate can function for both server and client roles.
When you select the Use Appliance Certificate and Key check box and click Save, the web
interface will be refreshed and the check box will be cleared. The client table will also not display the
Common Name and Fingerprint information from the appliance. However, the client is using the
appliance certificate as designed.
•
Upload the client certificate and key to authenticate to the other appliance.
3. Click Save.
Generate a New Certificate and Key
Follow these steps to generate a new SSL certificate and key for your Security Analytics Platform appliance.
1. Initiate an SSH session with the appliance and log in as root.
2. Using OpenSSL, generate a private key. You will need to specify the encryption type and bit value:
openssl genrsa [-<encryption_type>] -out localhost.key <key_size_in_bits>
If you create a private key with a passphrase (by specifying an encryption type), then, users must
enter the passphrase every time the system is rebooted. You may use an external program in place
of the built-in passphrase to bypass this security measure; however, omitting a passphrase (not
passing the encryption type) allows anyone who has the private key to impersonate the appliance or
to decrypt its data.
The following encryption types are available:
•
DES — Key encrypted with DES in CBC mode
•
DES3 — Key encrypted with DES in EDE CBC mode with a 168-bit key
•
IDEA — Key encrypted with IDEA in CBC mode
•
AES[128|192|256] — PEM output encrypted with AES in CBC mode
•
Camellia[128|192|256] — PEM output encrypted with Camellia in CBC mode

SSL Certificates and Keys
example
Encryption type AES256 with a 2048-bit key. (It is recommended that you specify 2048 bits or stronger):
openssl genrsa -aes256 -out localhost.key 2048
1. Generate a certificate-signing request (CSR) (not to be confused with CSR):
openssl req -new -key localhost.key -out localhost.csr
If you generate a CSR using a different method, you must upload the key that was used to generate
the CSR along with the signed certificate in step 5, below.
2. Export localhost.csr via SCP (or the equivalent) to your workstation.
3. Send the CSR to a CA to be signed. You will need to provide the country name, state, locality name,
organization name, organizational unit name, common name, email address, challenge password, and optional
company name.
4. The CA returns the signed certificate (localhost.crt).
5. You have these options to load the certificate and key to the appliance:
•
Upload both the certificate and the key to the appliance through the web interface.
If you use this method, you must move the key and certificate off the appliance before uploading
them, which may present a significant security risk.
•
Copy both files from the root directory to overwrite the current files:
mv localhost.key /etc/pki/tls/private/
mv localhost.crt /etc/pki/tls/certs/
service httpd restart
If you use this method, you bypass audit and record-keeping controls, which might be in violation of
your organization's security policy.
•
RECOMMENDED — Copy the key from the root directory to overwrite the current key, and then upload the
certificate through the web interface.
o
Copy the key to overwrite the old key:
mv localhost.key /etc/pki/tls/private/
o
On the web interface, select Settings > Security.
If you upload a key or certificate using the web interface and click Save, the internal HTTP server
automatically restarts. If you attempt to restart the HTTP server manually before both the key and its
corresponding certificate have been loaded, the HTTP server will not restart.

Go to Install from the Web Interface and follow the instructions to upload the certificate.
Disallow Connections That Use Low-Bit Encryption
1. Edit the ssl.conf file to allow only HIGH or HIGH and MEDIUM encryption ciphers, according to your preference:
vi /etc/httpd/conf.d/ssl.conf
2. Navigate to line 100:
100G
3. Remove :!LOW or :!MEDIUM and :!LOW from the default cipher suite:
Before: SSLCipherSuite RC4-SHA:AES128SHA:ALL:!ADH:!EXP:!MEDIUM:!LOW:!MD5:!SSLV2:!NULL
After1: SSLCipherSuite RC4-SHA:AES128-SHA:ALL:!ADH:!EXP:!MEDIUM:!MD5:!SSLV2:!NULL
After2: SSLCipherSuite RC4-SHA:AES128-SHA:ALL:!ADH:!EXP:!MD5:!SSLV2:!NULL
4. Press Esc and type :wq to save your changes.
5. Restart the internal HTTP server:
service httpd restart
Authenticated Proxies
If your appliance connects to the Internet via an authenticated proxy, and the proxy has a certificate handshake for
SSL traffic, add the CA certificate (PEM format) as follows:
cp /etc/pki/tls/certs/ca-bundle.crt /etc/pki/tls/certs/ca-bundle.crt.bak
openssl x509 -text -in <new_cacert>.crt >> /etc/pki/tls/certs/ca-bundle.crt
openssl verify -CAfile /etc/pki/tls/certsca-bundle.crt <new_cacert>.crt
Reboot to apply changes.

User Accounts and Groups
U SER A CCOUNTS AND G ROUPS
Select Settings > Users and Groups to configure local user accounts and their groups. With these groups you can
exercise RBAC. RBAC gives administrators the ability to assign specific view or modify permissions to "roles" (which
are represented by "groups" on the Blue Coat Security Analytics Platform), and then to assign the users to one or
more groups. In this way, administrators can impose a granular level of control over what users are permitted to do
or see on the Security Analytics Platform.
Local Users
•
You can create up to 256 local users on the Security Analytics Platform appliance.
•
User names and passwords support the UTF-8 character set.
•
Password strength can be configured on Settings > Security.
•
To enable two-factor authentication on an account, see Two-Factor Authentication.
Also see dsadduser in the Security Analytics Platform Reference Guide on bto.bluecoat.com.
Add a User
1. Select Settings > Users and Groups > Users.
2. Select Tools > New.
3. Under Login Details, specify the username and type the password twice. The username cannot contain spaces.
4. Optional — For User Groups, the default user group is present. You can delete this group and add other user
groups, as desired.
A user account that does not belong to any groups does not have access to the appliance.
5. Optional — Under Account Details specify the user's real name and email address.
6. Click Save.
If you lose access to all of the admin-level accounts on the web interface, log on to the CLI with root
permissions and run the following:
/gui/dsweb/Console/cake --app /gui/dsweb solera_acl elevate
<username>
where <username> is the name of an existing user account. The command places the user in a new
group with administrator privileges called elevated-admin-<YYYY-MM-DD>T<hh:ii:ss>. Log on with
this account using its original password, and then edit the account and the group in Settings >
Users and Groups.

User Accounts and Groups
Modify User Accounts
Use the controls on the Users and Groups page to modify or delete user accounts.
Local User — This user account was created directly on the appliance. When
you delete this user, the user’s group membership and login data are deleted, so
the user cannot log in to the appliance again.
Edit Account — Click to change the user’s password, enable or disable the
account, or change group membership.
Delete User — If a user is logged in when its account is deleted, the user’s next
action will fail.
Non-Local Account — This user has logged in to the appliance using remoteserver credentials such as LDAP or RADIUS. When you delete a non-local user
from the appliance, the user is deleted from all groups, but the account on the
remote server is unaffected. When the user logs in to the appliance again using
those remote credentials, the user account appears again on the Users and
Groups page in the default group, and the Admin must manually add it to any
other group.
To prevent remote users from automatically logging on to the appliance, do one
of the following:
•
Create a group that has no access privileges and designate it as the default
group.
•
In the LDAP search settings, select a Group DN that excludes unwanted users.
Enabling and Disabling User Accounts
•
User accounts are disabled automatically after a specified number of failed login attempts. (See Session
Controls.) You can re-enable the user account by clicking its Edit icon
•
and clearing Account Disabled.
Likewise, you can manually disable a user account by selecting the Account Disabled check box.

Logging and Communication
L OGGING AND C OMMUNICATION
Communication consists of logging, alerts, SNMP, and remote notifications.
For each event, the logs record the date and time of the event as well as the priority and the category.
You can also use the dslogdump command in the CLI for these settings. (Consult the
Security Analytics Platform Reference Guide on bto.bluecoat.com.)
Audit Log
Select Settings > Audit Log. Use the advanced filter to search the logs by priority, category, or event.
System Logs
From the CLI, you can access two different logs:
•
/var/log/audit/audit.log — User-initiated events written by auditd
•
/var/log/messages — System events from all components
Email Alerts
You can also use the dslc command in the CLI for many of these settings. (Consult the
Security Analytics Platform Reference Guide on bto.bluecoat.com.)
The Security Analytics Platform can send email alerts to any standard email address, either directly or through an
SMTP server gateway. Configuring the email settings will automatically send outbound emails for log entries to one or
more email addresses. You can specify any email address you prefer in the From field.
The Security Analytics Platform appliance uses the sendmail application and must therefore have
Internet access to send a message to an external email address. You can also configure the
appliance to point to an internal SMTP server; however, that SMTP server must be set up to relay
email from the Security Analytics Platform appliance.
1. Select Settings > Communication > Server Settings.
2. For To, type at least one valid email address. Separate multiple email addresses with a comma.
3. For From, type the email address to be displayed in the From field. Leave the field blank to use the system
name.
4. For SMTP Server and SMTP Port, type the server IP address or hostname and its port number.

5. Does the SMTP server require authentication?
Yes — For Username and Password, type the
credentials for SMTP server access.
No — Select the No authentication required
check box.
6. Select the Use STARTTLS check box if the SMTP server requires it.
7. For Default Email Address, type the email address that will be used whenever no email address is specified for an
Alert.
8. Click the Advanced tab.
9. Under Remote Notifications, enable the Email check box in the System Events row and click Save.
SNMP Settings
You can also use the dslc command in the CLI for many of these settings. (Consult the
Security Analytics Platform Reference Guide on bto.bluecoat.com.)
By default, the appliance will respond to incoming public queries from external SNMP devices. The Blue Coat
Security Analytics Platform can be configured to send SNMP traps and inform messages to external SNMP servers.
SNMP traps are error messages that do not require acknowledgement of receipt; SNMP informs require that the
receiving server send back an acknowledgement.
•
You can specify the same server to receive both trap and inform messages.
•
The Security Analytics Platform supports only SHA for authentication and AES for privacy.
Any special characters — including a space — that are entered in these SNMP fields will be
converted to an underscore (_). The exception is the @ character, which will be left as-is.
1. Select Settings > Communication > Server Settings and scroll down to SNMP Settings.
2. Under Polling, configure these settings:
•
Optional —Select Enable Polling.
o
•
Type the read-only username and read-only community name in the spaces provided, or accept the
default (public).
Optional —Select Enable Authentication.
o
Specify the authentication and privacy-encryption passwords.
3. Under Trap, configure these settings:
•
Specify the name for the trap community.
•
Specify the inform and trap server settings.
•
Optional —Select Enable Authentication.
o
Specify the read-only username and the authentication and privacy-encryption passwords.
4. Optional — Select Enable Authtrap.

Syslog Settings
Syslogs record information about the operation of a computer or computer-related device. Syslog messages can be
sent to an external syslog server.
You can also use the dslc command in the CLI for many of these settings. (Consult the
Security Analytics Platform Reference Guide on bto.bluecoat.com.)
1. Select Settings > Communication > Server Settings and scroll down to Syslog Settings.
2. Optional — If multiple syslog messages are issued simultaneously, select the Enable Coalescing check box to
group the messages before they are sent. This setting applies to all syslog servers.
3. For Syslog facility, select one of the following:
Kernel
User
Mail
Daemon
Auth
syslog
News
UUCP
Cron
AuthPriv
FTP
Local Use 0–7
LPR
4. For Syslog Servers, type the hostname or IP address and port number.
5. Click add a new host for multiple syslog servers to use the same facility.
To set up a many-to-many relationship among syslog servers and facilities, use dslc add syslog
server <server> <port> <facility>. Each server entry will be visible on the web interface but the
facility that is associated with each entry will not be visible at this time.

Central Manager
C ENTRAL M ANAGER
The Blue Coat Security Analytics Platform CMC is a dedicated appliance that is licensed as a CMC. With the CMC,
you can manage multiple sensors (formerly "managed appliances") and analyze data from the sensors. Specifically,
the CMC provides:
•
An aggregated view of data across multiple sensors
•
An interface for sensor management
•
Centralized sensor software upgrades
This illustration shows one possible configuration: three sensors being managed by a CMC. Notice that all
connections between the sensors and the CMC are conducted over VPN connections. The browser for the CMC’s
web interface uses an HTTPS connection.
All communications between sensors and CMCs are conducted over a dedicated VPN, with each link between a
sensor and the CMC having its own connection. Communications over the VPN subnet are protected by industrystandard SSL/TLS encryption that uses 1024-bit RSA-encrypted keys.
•
Because each of these connections is a separate tunnel, no sensor can "see" or communicate
with another sensor through the VPN.
•
The VPN may cross network boundaries.
•
CMC-to-sensor traffic that is captured by the system is classified as udp > openvpn or tcp >
openvpn in the Tunneling application group.

Central Manager
CMC Initial Settings
1. Complete the steps to configure a standalone appliance.
2. The Central Management Settings page should be the next display on the CMC interface, after the Initial Settings
page. If you are not on this page, select Settings > Central Management > Settings.
3. Select TCP or UDP as the VPN connection protocol.
4. Specify the following:
•
Subnet — Specify the IP addresses to be used for the VPN connections between the sensors and the CMC.
The default is 10.8.0.0/16. This subnet must be different from any other subnet on your network.
•
Netmask — Specify the netmask for the VPN subnet. The address space should be large enough to provide
4 IP addresses for each sensor that the CMC controls.
•
Port — Specify the port for the VPN connection on the sensors: Default is 1194. It is strongly recommended
that you not use ports 22, 80, or 443, because they are reserved for other applications and protocols.
•
If you have more than one CMC on your network, the VPN subnets must be unique for each
CMC.
•
The CMC is always xx.xx.xx.1 on the VPN subnet, and it assigns subnet addresses to the
sensors automatically (xx.xx.xx.2–254).
•
Your corporate firewalls and routers must permit the traffic between the CMC and the sensors
that you want to manage through the CMC. Verify that the VPN, port, and protocol settings
(including HTTPS) permit the connections.
5. Click Save. Registration and configuration may take several minutes, depending on your network conditions. The
VPN network settings are being established during this time.
Do not change the port numbers for HTTP (80) and HTTPS (443) on the Security Settings page, or
the CMC will not connect to the sensors.

Manage One Sensor with Multiple CMCs
You may set up a many-to-one relationship among multiple CMCs and one sensor. Follow these steps:
1. Verify that each CMC is on a different subnet.
2. On each CMC that will manage the sensor, generate a key for the sensor.
3. Add the authorization key file to the sensor on Settings > Central Manager.
Do not attempt to push-upgrade the same sensor from different CMCs at the same time.
User Accounts and Groups on the CMC
As with standalone appliances, access to a Blue Coat Security Analytics Platform CMC is granted by membership in a
group. To these groups, you can assign permissions at a granular level; any user in the group has those permissions
on the appliance.
Likewise, users who access a sensor through the CMC must be assigned to a group that specifies which
permissions the user has on the sensor. On the CMC, these are called "Remote Groups."
For instructions on assigning local permissions to groups — including LDAP groups — consult User
Accounts and Groups for standalone appliances.
Sensor Access
There are two methods for granting sensor-access privileges to a user:
•
Authorizations — Individual access to the sensor, according to remote-group permissions
•
Remote Groups — Provides RBAC for groups of users
You may use one or both of these methods, i.e., a user may be present in both the Authorizations field and in a
remote group that is present in the Remote Groups field.
Authorizations
1. On the CMC dashboard, click Manage Sensors.
2. Click Edit
for the sensor.
3. For Authorizations, type the first few letters of the username and then select it when it becomes visible.
4. Click Save.
Remote Groups
•
See Create or Modify a Group for instructions on creating a remote group. This process is identical to creating
user groups on a standalone appliance.

Remote Groups: Example Setup
The following example describes how to assign specific sensor permissions to different users using the CMC's
remote groups. This example does not include instructions on assigning permissions to the CMC itself.
Network Setup
The example network has three sensors that are controlled exclusively through one CMC.
•
Sensor 1 monitors general workstation traffic in the organization.
•
Sensor 2 monitors traffic that includes a public-facing web site, hosted on a cluster of HTTP servers that are
on VLAN 7. Other file servers are on different VLANs that the sensor also monitors.
•
Sensor 3 monitors traffic that includes VLAN 12, which contains executive workstations, devices, and servers
that contain sensitive corporate, accounting, and human-resources data.
Requirements
The organization needs the following sensor functions to be performed by different users:
•
Full administrative access to modify all settings and accounts
•
Log auditing to check for conformity to network policy as well as the archiving of logs
o
Only one user is to be entrusted with auditing the traffic on VLAN 12
•
Security enforcement, which ensures that all devices and user accounts conform to security policies
•
General analysis of all LAN traffic to check for malware, breaches, and usage violations
o
•
Only one user is to be entrusted with analyzing the traffic on VLAN 12
Monitoring and analysis of all incoming traffic to the public web site, but no access to other LAN traffic

Design
The requirements are best fulfilled with five remote groups:
•
admin — All permissions. This remote group is already present on the CMC.
•
auditor — View and download the audit log. This remote group is already present on the CMC.
•
Security — Modify all sensor-access settings such as authentication, certificates, and the firewall.
•
Analyst — View and modify all Analyze pages, import PCAPs from local and remote sources, view and
download audit logs, view the capture summary graph, modify data-enrichment settings.
•
Website — View and modify all Analyze pages, import PCAPs from local sources, only view web-related
traffic on VLAN 7.
The groups will be assigned permissions on the sensors as follows:
•
Sensor 1 — admin, Analyst, Auditor, Security
•
Sensor 2 — admin, Auditor, Security, Website
•
Sensor 3 — admin, Security
In this example, eight users have access to the sensors:
•
admin — Senior system administrator
•
Analyzer1 — Senior analyst
•
Analyzer2 — Associate analyst
•
Auditor1 — Senior auditor
•
Auditor2 — Associate auditor
•
Watchman — Security compliance administrator
•
WebMaster1 — Web site administrator
•
WebMaster2 — Web site administrator
The order in which the remote groups, users, and sensor permissions are created is flexible. A simple sequence is
presented here:
•
Create the remote groups
•
Create the users
•
Assign sensor authorizations (the example assumes that the sensors are already connected to the CMC)

Data Aggregation
With two or more sensors selected, the summary screen displays aggregated data from the sensors. The Reports,
Extractions, and Geolocation views have a drop-down arrow at the left of the status bar. Expand to see the status for
each individual sensor.
Aggregation is not available for the following:
•
Capture pages
•
Statistics pages
•
Settings pages
For these pages, select a sensor from the selector in the upper-right corner of the interface to view each sensor's
page separately.
Multi-Sensor Summary Views
On all of the Summary pages (Default, Social, Web, IP Layer, Ethernet Layer, Threat Intel) the data is aggregated from
all selected sensors. When you create or edit a view on the CMC (by deleting or adding widgets, for example), the
changes are not propagated to the individual sensors.

Multi-Sensor Reports
The reports that are available on the CMC are the same as for a standalone appliance.
The CMC does not generate reports for the sensors — each individual sensor generates its own
report and passes the data to the CMC. However, the saved, aggregated report views are stored on
the CMC.
If you are viewing the data from more than one sensor, click on a row to show the breakout per sensor.
In the Application report, above, DNS data has been captured by four sensors.
Multi-Sensor Extractions
•
On the Extractions page, the display in the Distribution panel is aggregated, whereas the items listed in the
Results panel are not.
•
In a multi-sensor environment, the Sensor column shows which sensor captured the artifact.
•
In the expanded view, the sensor name is also visible.

Multi-Sensor Favorites
On the Favorites and Actions pages, a Sensors column shows the where the item is present, or for the Alerts page,
which sensor generated the alert.
•
•
If the same favorite is present on multiple sensors, click the [N] more link to see the full list of sensors.
When creating a favorite, you can apply it to one or multiple sensors. In the Sensors field, all sensors appear by
default. Delete any sensors to which you do not want to apply the favorite.
•
Any favorite that you add to the Filter field must already be present on the sensor(s) where the
new favorite is to be created.
•
When you create an unshared favorite through the CMC, it will be visible only through the CMC
to the user who created it. If the favorite is shared, it is visible on the sensors and to other CMC
users.
•
You can use the Remove from list on the delete dialog to delete a shared favorite from your
account only or from all accounts.
•
When you delete a favorite, you also delete other favorites, actions, and alerts that contain the
favorite. See Delete Favorites.

Multi-Sensor Actions
•
When creating an action, you must select the sensor on which the action is to be created.
•
When creating an action, the favorite(s) in the Favorites/First Event field must already be
present on the sensor(s) where the action is to be created.
•
When you create an unshared action through the CMC, it will be visible only through the CMC
to the user who created it. If the action is shared, it is visible on the sensors.
•
If the action is shared, you can use the Remove from list on the delete dialog to delete it from
only your account or from all accounts.
Multi-Sensor Alerts
•
On Analyze > Alerts, you can see each instance of a triggered alert. The sensor that registered the hit is
displayed in the Sensors column.
Multi-Sensor PCAP Files
•
You can download PCAP files from the CMC from any Analyze page (Summary, Reports, Extractions,
Geolocation).
•
The CMC creates a single ZIP file that contains a separate PCAP for each sensor.
PCAP Import
•
PCAP imports cannot be aggregated.
•
When importing a PCAP to a sensor via the CMC, only the Remote Server option is supported for Import
from.

Multi-Sensor Geolocation and Google Earth
Although the Geolocation and the Google Earth tools can show maps with both aggregated data and individual
sensor data, the Geolocation tool in the CMC does not identify the sensor that the data came from. With the Google
Earth tool, you can choose to display either aggregated data or data from any individual sensor.
When you download a Google Earth file with multiple sensors selected, you can choose whether to view the
aggregated data or to view sensor data separately.
There are two methods to link the source sensor to a geographic location:
•
Select the IP address, filter on that and view reports.
•
Deselect all but one sensor and regenerate the Geolocation image; you may need to repeat this
for each sensor until you find the desired data.
Multi-Sensor Data Enrichment
For every sensor that is to use the data-enrichment resources, you must install a license. If the data-enrichment results
are to be viewed through the CMC, the CMC must also have a license for each data-enrichment resource.
Sensors may access the data-enrichment resources either through their CMCs or through their own Internet
connections. Go to Settings > Data Enrichment on each sensor and configure the settings accordingly.
Multi-Sensor Communication Settings
For settings that are related to remote notifications, scheduled reports, and other communication settings, the CMC
will not synchronize its SNMP, SMTP, or syslog server information with that of the sensors.
This non-synchronization permits you to specify separate servers for the CMC and for each sensor.

Upgrading Sensors
You can use a Blue Coat Security Analytics Platform CMC as a software repository for the sensors so that you
download the upgrade from the Internet only once. (Alternatively, the sensors can be upgraded from their own
interfaces in the same way as standalone appliances.)
CMC Upgrade Repository
For the CMC to act as an upgrade repository for its sensors, it must have at least one upgrade server configured on
the CMC repository as well as an upgrade image in the CMC repository.
An upgrade image in the CMC repository is available to the sensors for upgrade but it is not
available for the CMC itself to upgrade. Select Settings > Upgrade to perform an upgrade of the
CMC.
On the dashboard, click Upgrade Repository. During the licensing procedure for the CMC, the upgrade server
upgrade.soleranetworks.com should have been added to the CMC's External Repository list.
If no upgrade server is listed, follow these instructions to add the upgrade server:
1. On the CMC, do one of the following:
•
Select Settings > Central Management > Upgrades.
•
On the dashboard, click Upgrade Repository.
2. Click New.
3. For Protocol, select https.
4. For Host, type upgrade.soleranetworks.com
5. For Path, type /upgrades/
6. For Username and Password, contact Security Analytics Support.
7. Click Save. The upgrade server is saved under External Repository.
This same server will also be listed on the CMC's Settings > Upgrade page.
