I have two questions regarding default audit behavior (i.e. auditd is running,
but there is nothing in audit.rules but "-D" and "-b 256"):
1) what is being audited?
2) can I use the -D command to prevent those things from being audited?
I am required to have auditing running, but what I need to audit is specific.
One server in particular is slow (a 750 MHz Pentium III) to start with, and
default auditing is slowing it down to a crawl.

Nothing except the hardcoded events in various apps and SE Linux avc events.
The default settings is to cater to SE Linux users that have no other use for
the audit system.

audited?
Nope. You'd have to do "-e 0" to do that. Even then, SE Linux will still
send
things to the audit system.

Do you have any oprofile data showing the bottleneck? I'd be curious. Also,
what kernel are you using? We've tested the performance of the audit system
and its not a big hit unless you have a lot of syscall rules loaded. Watches
are cheap.
