IMHO, this is not a problem to solve by monitoring, it is a problem to be 
solved by:
-authorization for actions/commands (e.g. sudo access to specific commands, 
instead of root shell access)
-accounting/auditing (e.g., in case root shell access is required, the 
commands/screen output should be recorded against the user who started the 
root shell session)
-security auditing

Centralised authentication (which implies that the only local accounts 
required are for "system" use, not for users) can also help reduce the amount 
of work in picking up and fixing incorrect user/group changes.

If monitoring when changes were made to local files forms one part of your 
process, fine, you can use the 'FILE' monitoring feature with the mtime check.

However, I would really hope this is not the only thing you are putting in 
place to solve this problem.
