Promisec has announced what it calls the first encyclopedia of internal threats. The Internal Threat Encyclopedia contains both shady and clearly legitimate software that is subject to abuse. For instance, you'll find Laplink and Timbuktu in there, both straight-up remote control programs. The top 5 internal threats, according to the encyclopedia, includes (today) Google Talk, Skype and MySpace. These applications are well known for sure, but the encyclopedia entries are a handy collection of the problems each can cause. It could be useful if you need to explain why you're setting rules against one of them.
