This is an area I feel I'm sorely lacking as a sysadmin. I'm so busy I don't spend as much time as I'd like trawling for new information, and I've fallen sorely behind. I could use some help finding good rss feeds and mailing lists to stay up to date. Especially on the security/spam/antivirus/malware front. I'd like to know about the latest threats so I can actively block them with DNS. My RSS collection is particularly pathetic:
Schneier on Security
WSUS Product Team Blog
Windows Update Product Team Blog
Windows Vista Team Blog
Microsoft Certified Professional Magazine
My environment is entirely Windows, so I'm not particularly interested in Linux feeds. Anyone have any recs?
