Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful uses of the "postqueue" by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file:

-a always,exit -F path=/usr/sbin/postqueue -F perm=x -F auid>=1000 -F auid!=unset -k privileged-unix-update

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify that an audit event is generated for any successful/unsuccessful use of "postqueue" by performing the following command to check the file system rules in "/etc/audit/audit.rules":

$ sudo grep -w "postqueue" /etc/audit/audit.rules

-a always,exit -F path=/usr/sbin/postqueue -F perm=x -F auid>=1000 -F auid!=unset -k privileged-unix-update

If the command does not return a line, or the line is commented out, this is a finding.
