Nope. If auditd is running, that's all you need. If you see no sealerts in
/var/log/messages, or AVCs in /var/log/audit/audit.log, be happy. The
messages are for specific AVCs on *your* system, they're not generic.

I don't think so. I think you need something like Citrix, or the mks
toolkit, or something like that, if you're on WinDoze.
