Day two of Black Hat 2011: Peiter (Mudge) Zatko

Deb Shinder reports on Peiter Zatko's address from Black Hat 2011, where he talked about system complexity and increasing attack surfaces.

Yesterday's keynote at BlackHat 2011 was given by a long-time member of the "establishment," Cofer Black. Today's events were kicked off by "Mudge" (Peiter Zatko), well-known in the hacker community for writing L0phtCrack, who has now joined DARPA and is trying to bridge the gap between hackers and the government.

He started out talking about how the growing complexity of today's operating system environments make things easier for malicious coders, and how the number of lines of code correlates to the complexity of the system. This in turn presents a larger attack surface, in addition to the performance and reliability issues it causes; he discussed a study from IBM showing that for every 1000 lines of code, 1-5 bugs are introduced. He also showed how, regardless of application size, the system must load the same support functions in this complex runtime environment. He also pointed out how additional layers of security actually add to the complexity and can increase the attack surface, as well.

Mudge wrapped things up by discussing his efforts to bring that agency into the 21st century to more effectively secure the nation's computers and network infrastructure by making it possible for individual researchers and small boutique security companies to compete with giant government contractors for funding. He discussed how the typical government program now takes 81 months - six years - to implement and how his "Cyber Fast Track" program will change that. This was welcome news for underfunded or unfunded security researchers who, in order to support themselves, must work at a "day job" and make important security breakthroughs in their off time.
