Title
The macOS system must be configured to audit all changes of object attributes. (Cat II impact)
Discussion
The audit system must be configured to record enforcement actions of attempts to modify file attributes (fm). Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. One common and effective enforcement action method is using access restrictions (i.e., modifications to a file by applying file permissions). This configuration ensures that audit lists include events in which enforcement actions attempts to modify a file. Without auditing the enforcement of access restrictions, it is difficult to identify attempted attacks, as there is no audit trail available for forensic investigation.

Check Content
Verify the macOS system is configured to audit all changes of object attributes with the following command: /usr/bin/awk -F':' '/^flags/ { print $NF }' /etc/security/audit_control | /usr/bin/tr ',' '\n' | /usr/bin/grep -Ec '^fm' If the result is not "1", this is a finding.
Fix Text
Configure the macOS system to audit all changes of object attributes with the following command: /usr/bin/grep -qE "^flags.*fm" /etc/security/audit_control || /usr/bin/sed -i.bak '/^flags/ s/$/,fm/' /etc/security/audit_control;/usr/sbin/audit -s
