#1 - Your linux boxes are immune. Nimda/code red works on IIS only.
#2 - what version of linux are you running? More specifically, are you
using ipchains or iptables? Iptables can be configured to filter out
"nimda" packets with a bit of elbow grease, but to my knowledge ipchains
cannot.

I have found "securing and optimizing linux" (redhat biased) is a good
starting point. Go to linuxdoc.org and look under the guides section.

IDS - snort
antivirus? ... tripwire (checks binaries to see if they've changed). {{
there aren't too many linux "viruses", but there are plenty of trojans }}
security tools? - nmap, netcat, nessus.. hmm about you just check out this
list? http://www.nmap.org/tools.html

cheers, enjoy linux :)

Peter
