Fix Recommendation

Configure RHEL 9 to generate audit records upon successful/unsuccessful attempts to use the "setfacl" command by adding or updating the following rule in "/etc/audit/rules.d/audit.rules":

-a always,exit -F path=/usr/bin/setfacl -F perm=x -F auid>=1000 -F auid!=unset -k perm_mod

To load the rules to the kernel immediately, use the following command:

$ sudo augenrules --load

Check Contents

Verify that RHEL 9 is configured to audit the execution of the "setfacl" command with the following command:

$ sudo auditctl -l | grep setfacl

-a always,exit -S all -F path=/usr/bin/setfacl -F perm=x -F auid>=1000 -F auid!=-1 -F key=perm_mod

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