Internet Storm Center E-Mail Notification

Intenet Storm Center (ISC) provides a free analysis and warning service to thousands of Internet users and organizations, and is actively working with Internet Service Providers to fight back against the most malicious attackers.

The ISC relies on an all-volunteer effort to detect problems, analyze the threat, and disseminate both technical as well as procedural information to the general public.

If you want to receive email notification on their ISC news (highly recommended!), you can subcribe to receive the ISC E-Mail Notification. It's BETA service.
