Advanced Persistent Threat: An Iterative Approach
Posted by Tom Cross on March 21, 2011 at 11:40 PM EDT.
In February, I gave a talk at IBM's Pulse conference on Advanced Persistent Threat. There is no simple solution to combatting APT threats on a computer network - fighting APT becomes a process that you engage in over time. The first step involves a multifaceted effort to detect APT activities in your environment. Its not always possible to detect everything - the goal is to detect something. Detecting something gives you a foothold. Once you've detected an attack, you analyze it to gain actionable intelligence that allows you to remediate that attack and augment your detection efforts. By iterating through this cycle you get better and better at staying on top of sophisticated threats.
While this talk borrows some material from the SANS Webcast on APT that Jon Larimer, Will Gragido, and I gave back in June of this year, I have built on top of that material to provide a set of process recommendations that more tangible. You can stream the video here and download my slides here. Also, there will be some more information on this subject in the upcoming X-Force Annual Trend Report.
