Established in 1988, the CERT Coordination center (CERT/CC) is “a center of Internet security expertise”. Here, you’ll find almost everything you would want to know about the current state of internet security, in easily browsable form. Information about all the worms & Trojans out there, what’s being done about today’s problems, what you can do, research & analysis-it’s all there. Definitely a periodic must-visit.
