Fix Recommendation

Navigate to and open:

/etc/audit/rules.d/audit.STIG.rules

Add or update the following lines:

-w /usr/sbin/usermod -p x -k usermod
-w /usr/sbin/groupmod -p x -k groupmod

At the command line, run the following command to load the new audit rules:

# /sbin/augenrules --load

Note: An "audit.STIG.rules" file is provided with this guidance for placement in "/etc/audit/rules.d" that contains all rules needed for auditd.

Note: An older "audit.STIG.rules" may exist and may reference older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.

Check Contents

At the command line, run the following command to verify an audit rule exists to audit account modifications:

# auditctl -l | grep -E "(usermod|groupmod)"

Example result:

-w /usr/sbin/usermod -p x -k usermod
-w /usr/sbin/groupmod -p x -k groupmod

If either "usermod" or "groupmod" are not listed with a permissions filter of at least "x", this is a finding.

Note: This check depends on the "auditd" service to be in a running state for accurate results. The "auditd" service is enabled in control PHTN-40-000016.
