For the ones who are not close to security related slang, Catch The Flag is an online hacking game that consist in hacking stego, web, network, etc in order to get passwords (the flags) and catch them all before the rest of the contestants.

Platform for Privacy Preferences Project (P3P) is supposed to be a protocol which gives the opportunity to declare the intended usage of collected information of web browser users in specific pages, in order to make a standardized way of protecting user privacy. At first I thought this was a wonderful idea, and reminded me a lot of the cookies policies problems. This should be an example of syntax of statements for policy (taken from Web Privacy with P3P by Lorrie...
