Most people do change management through trust, but verify, where change
requests are submitted, approved, then an administrator implements by hand,
and then replies that it was done successfully or not and what the failure was.
Then at some point, these changes are verified by someone else and confirmed
to been in place.

You could try to automate the verification process by using IDS software to log
all the environment changes, then match those up with change requests. Any
that happen without a change request were unauthorized and need to be rolled
back.

This way you get 2 birds with 1 stone, change management verification and
intrusion detection. Couple that with a good backup/restore strategy and you
should have the major bases covered.
