If you are interested in keeping up to date with the latest vulnerabilities and security threats checkout the Qualys @RISK Newsletter. The newsletter is delivered weekly and contains a lot of good information on the latest vulnerabilities and advice on how to fix them. This is a great weekly newsletter and I highly recommend it if you are concerned with keep your systems and network secure.

Another great source for network and computer security information is the US Governments Technical Cyber Security Alerts. There you will find current information about current security issues, vulnerabilities, and exploits. Not quite as detailed as the Qualys @RISK Newsletter but still a good resource.
