Configure SLEM 5 to generate an audit record for all uses of the "usermod" command.
Add or modify the following line in 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
To reload the rules file, restart the audit daemon:
> sudo systemctl restart auditd.service
or issue the following command:
> sudo augenrules --load
Verify SLEM 5 generates an audit record for any use of the "usermod" command with the following command:
> sudo auditctl -l | grep -w '/usr/sbin/usermod'
-a always,exit -S all -F path=/usr/sbin/usermod -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-usermod
If the command does not return any output, this is a finding.
Note: The "key=" value is arbitrary and can be different from the example output above.
