Security Landscape
The industry today is more dangerous than ever before
–
Today’s threats are evolved and bypass traditional detection measures



–
Hactivisim is a threat affecting everyone
–
Targeted attacks are now common in the industry


–
–
Attacks leveraging zero-day vulnerabilities
Custom malware
Your industry DOES affect your probability of attack


Increased complexity
Increased stealth (bypass FW, IPS, UTM, WCF)
Dynamic
Patterns and attack volume vary significantly between industries (healthcare, energy,
finance, etc.)
“Intelligence” will help improve your defenses against industry attacks
Intelligent Analysis | Overview

What is “Intelligence”?
– Information put into context and in a form that can be acted upon
– Intelligence is derived from data
Data

Information
Intelligence
Most organizations have the data but can not convert it into “intelligence”
Intelligent Analysis | Overview

What is Intelligent Analysis?
– Advanced event analysis and pre-emptive intelligence that can
protect you against present and emerging threats

Live-analysis and correlation of device security events
– Signature, pattern and anomaly detection
5

Industry analysis of the external threats that are likely to impact
your environment (Global, industry, targeted, geographical)

Tailored reporting containing metrics and expert advice that
enable the effective measurement and tracking of information

Okay we now know what Intelligent Analysis is so what’s the
problem?
The problem
– How do you monitor external sources (internet, social media,
etc.) for relevant information?


Manual analysis aka the “swivel chair” approach
isn’t effective

You need to enlist the help of some tools to manage
the data

Analysis process
Analysis process | Overview

Two-step approach to analysis
1) Transform data to information
- Ensure data articles are relevant
- Categorize relevant data articles
2. Transform information to actionable intelligence
- Rate and prioritize data articles
- Research and answer the three W’s
- What is it?
- Why is it important?
- What should you do about it?

Step 1 - Transforming data to information
– There is a little known tool named NewsPet that can help you transform
data to information

Industry Threat Activity
Correlate industry activity with event activity within your
environment

Add context to real-time activity

Serve as early-warning for threats in the industry that are likely to impact your
organization
Meaningful reporting can help you understand the threats targeting
your organization and your current level or protection
