All Good Suggestions. To answer Erik's question on scoring per my experience last week at the NYC CTF.
Red Team members were required to run a script on the comrpomised system once it was compromised to gain a point for the hack. They were encouraged to take data but no DDOS were allowed. However, they could take down systems towards the end of the day (although they would not getting points for doing so but the blue team would gain points for systems down - more points are bad for blue). Blue Team Members with the lowest score won. They needed to keep systems and services online. If compromised they could regain (subtract some points) if they were able to get the systems online quickly and accurately report data loss to the FBI field office. (Paul and Renald actually did a good job destroying the team that won but because they were able to restore and start over (DR) they regained their lead. So with that said while tools (both preventative and reactive) would certainly help the blue team, I think the most important thing is to be organized, have a plan, have the expertise (one person for linux, one for windows, one for web apps/databases, and one for networking), and know when to say we are screwed lets implement our DR plan. And ss Erik pointed out lock down the systems! Some command line and gooyee tools could certainly have helped with this but would be no substitute for experience and organization. Scripting command line stuff and GPO's would certainly help in a large environment (have quite of bit of experience there) but in an exercise like this it may just slow a team down (better to do it manually since there were only a handful of systems). So AV, log monitoring, best practices (i.e. all of Erik's preventative suggestions and more), and things like TCSTools switchblade for incident response would all be helpful. I'm wondering if the questions of what tools is the right question. Maybe the question is what best practices? Just My 2 1/2 cents.
