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.

Aunque estas vulnerabilidades han afectado a procesadores de todo tipo, hay una empresa que ha quedado especialmente señalada: Intel.

Intel (al igual que la mayoría de fabricantes) no te proporcionan una versión accesible del código del software que se ejecuta en el interior de su hardware y sin el que el mismo no puede funcionar, generalmente para esto se alegan “motivos de seguridad”....


By chance I discovered an old World Wide Web consortium (W3C) project that has been abandoned for a while. 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.

This should be an example of syntax of statements for policy (taken from Web Privacy with P3P by Lorrie...
