So, you've got someone inside, who's doing nasty, or stupid, things?
The most obnoxious, stupid idea I've had to deal with was a few years ago,
when the company I was subcontracting for put something in the .profile to
log every. single. command. a developer issued....
However, since you've set up sudo for them, their commands should *also*
be in /var/log/secure. Of course, what you need is a script to grab that,
and attach to it which user had sudo'd.
Hmmm, as I type that, I just got to thinking: do they need all root
privileges, or do specific users only need certain commands? If so, it's
easy enough to limit what commands they're allowed to run under sudo - man
sudoers.
