I don't think I've mentioned SANS on this blog. I should. SANS stands for SysAdmin, Audit, Network, Security Institute. The publish a variety of newsletters on security threats and protecting a business from them.
In addition, they provide a variety of educational opportunities for system administrators and security officers.
Another great security resource is CERT (Computer Emergency Response Team) at Carnegie Mellon University.
It's hard to keep up-to-date on all the risks, but if you have sensitive data or a connection to the Internet, you need to be informed of the risks.
