I'm hoping to be told otherwise, but the cleanest and most maintainable way that
I've seen to do this is to make two rules.
First Rule: Ignore user 505
Second Rule: Audit everyone
Auditd should stop at the first rule matched. It does add more rules but seems to be the
most stable across auditd versions.
Also, that auid!=42... should probably be near the top of your rules since it will get hit
the most and I'm assuming that you don't ever want to audit
anonymous accesses to most items.

All,
New auditd list member here. I just started playing around with auditd. I was wondering
if someone might be kind enough to answer a question I have.
I am attempting to create a rule that will audit privileged commands for UID's
greater than 500 but ignore one particular user that falls under this
rule. The user I am trying to ignore is the only user that should be touching the file.
Below is the rule.
#### BEGIN RULE SNIP ####
## Ensure auditd Collects Information on the Use of Privileged Commands
-a always,exit -F path=/opt/varonis1.6.0106/bin/ls -F perm=x -F
auid>=500 -F auid!=4294967295 -F auid!=505 -k privileged
#### END RULE SNIP ####
Is the rule syntax above correct? If not how would I audit all users with UID above 500
but still ignore one particular user?
Thank you and happy holidays,
