What setups do you have? I'm interested in hearing how much work your auditing setups do for you... and what pieces you have to give you data. (nmap, nessus, eeye, iis, etc etc)
I'm leaving a third party solution to use nmap and nessus... and putting together some kind of cron'ed diff on the results of an nmap scan to look for changes.
