For anyone interested in network security, here's a couple of websites for both products and security news/information:

Arbor Networks and their dashboard
Cisco Security Centre
McAffee Threat Centre
Net Forensics
SANS and the Internet Storm Centre. For all those interested, SANS run security training courses aimed at achieving GIAC certifications and they're in Canberra from June 29 - July 4th. Alas, while my last employer was putting me on the bootcamp course, my current employer had already promised the course to others before I started and I must wait my turn.

And while it isn't specifically a security product; Wireshark is brilliant and I highly recommend having a muck around. The first time I ever used it, it was still called Ethereal and it allowed me to reconstitute an RTP stream (VoIP call) and eavesdrop on a conversation during a security course.
