| Description | ||||
| The audit system must be configured to record enforcement actions of access restrictions, including failed file write (-fw) attempts. Enforcement actions are the methods or mechanisms used to prevent unauthorized access and/or changes to configuration settings. One common and effective enforcement action method is using access restrictions (e.g., denying users access to edit a file by applying file permissions). This configuration ensures that audit lists include events in which enforcement actions prevent attempts to change a file. Without auditing the enforcement of access restrictions, it is difficult to identify attempted attacks because no audit trail is available for forensic investigation.

Check Text (C-268465r1034335_chk)
Verify the macOS system is configured to audit all failed write actions on the system with the following command:
/usr/bin/awk -F':' '/^flags/ { print $NF }' /etc/security/audit_control | /usr/bin/tr ',' '\n' | /usr/bin/grep -Ec '\-fw'
If the result is not "1", this is a finding.
Fix Text (F-72396r1034334_fix)
Configure the macOS system to audit all failed write actions on the system with the following command:
/usr/bin/grep -qE "^flags.*-fw" /etc/security/audit_control || /usr/bin/sed -i.bak '/^flags/ s/$/,-fw/' /etc/security/audit_control;/usr/sbin/audit -s
