Fix Recommendation

Configure AlmaLinux OS 9 to generate audit records upon successful/unsuccessful attempts to use the "usermod" command.

Add the following to the "/etc/audit/rules.d/audit.rules" file:

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

Merge the rules into /etc/audit/audit.rules:

$ augenrules --load

Check Contents

Verify that AlmaLinux OS 9 is configured to audit the execution of the "usermod" command with the following command:

$ auditctl -l | grep usermod

-a always,exit -S all -F path=/usr/sbin/usermod -F perm=x -F auid>=1000 -F auid!=unset -F key=privileged-usermod

If the command does not return an audit rule for "usermod" or any of the lines returned are commented out, this is a finding.
