I don't see why anybody with a network connection isn't running some sort of intrusion detection/prevention system whether it be hosted based or network based....this should especially include the government's systems as well. Snort is now included in quite a few of the specialized security distros. In fact I know of at least two distros that are specifically designed for IDS/IPS only and can be up and monitoring traffic in less than 30 minutes.

*Disclaimer: Yes I am a developer for EasyIDS but it doesn't change the fact that people should still have an IDS/IPS in place.

Welcome to the new regime, which will probably end up as corrupt as the old regime. Two of his appointees are already under fire for questionable activities in their past. The most recent being the Treasury appointee who owed back IRS taxes.
