Forensics has traditionally been viewed as very system-­‐specific Only recently, has external (off of the target machine) sources of ĐŽƌƌŽďŽƌĂƚŝŶŐĞǀŝĚĞŶĐĞďĞĞŶĐŽŶƐŝĚĞƌĞĚ͚ǀĂůƵĂďůĞ͛ďLJŝŶǀĞƐƚŝŐĂƚŽƌƐ Image Source: http://infosecnewbie.blogspot.com/2010/11/open-source-forensics-fundamental.html

Point 1 ʹ Platform forensics: possible tools Platform Forensics Point 2 ʹ Network forensics ‡ If a host needs to talk to the world, it needs to leverage the network ‡ Likewise, if an attacker interacted with the machine remotely there may be a trail ‡ Deep packet inspection (DPI), network flow generation/collection/inspection, packet sniffers and flow analytics engines Image Source: http://www.imdb.com/media/rm2382076160/ch0001814

Point 5 ʹ Orchestration: possible tools Orchestration What will it look like? Data Reduction Corroborators Orchestration Network Forensics Platform Forensics The result? ‡ Many hands make light work ʹ this extremely true with regards to forensics ‡ Evidence on a system can almost always be enriched by external sources of corroborating evidence ‡ Hindsight is 20/20 ʹ deploy now to help later Image Source: http://totallyradicalsportz.wordpress.com/2010/10/11/smackfest/
The result? ‡ Vendors must strive to ͚ƉůĂLJ
