The Photon operating system must generate audit records for all access and modifications to the opasswd file.

Description
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

ℹ️ Check
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
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.
