Hello!
We don't use AIDE exclusively at a client site, but in combination
with Tripwire. We think tripwire is a little more secure becuse it
uses signed databases. So we protect aide.db with Tripwire. AIDE is
used for the parts tripwire can't do because of it's limited
configurability.
Here is an AIDE policy we use at the client site:
