Check Text ( C-62639r933756_chk )
At the command line, run the following command to verify an audit rule exists to audit the opasswd file: # auditctl -l \| grep -E /etc/security/opasswd Expected result: -w /etc/security/opasswd -p wa -k opasswd If the opasswd file is not monitored for access or writes, 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.

Fix Text (F-62548r933757_fix)
Navigate to and open: /etc/audit/rules.d/audit.STIG.rules Add or update the following lines: -w /etc/security/opasswd -p wa -k opasswd 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.
