Intrusion Detection Software Upgrade
The ol' (open source) Tripwire was getting long on the tooth (and it doesn't run under RHEL4/SL4) so I recently rolled out AIDE. It's pretty much a drop in replacement for Tripwire--at least I was able to write a script to munge it's output into Tripwire style output so our existing IDS and meta file integrity checking systems don't need upgrading.
