Description
The audit log files must not contain ACLs. This rule ensures that audit information and audit files are configured to be readable and writable only by system administrators, thereby preventing unauthorized access, modification, and deletion of files.

Check Text (C-268432r1034236_chk)

Verify the macOS system is configured without ACLs applied to log files with the following command: /bin/ls -le $(/usr/bin/grep '^dir' /etc/security/audit_control | /usr/bin/awk -F: '{print $2}') | /usr/bin/awk '{print $1}' | /usr/bin/grep -c ":" If the result is not "0", this is a finding.

Fix Text (F-72363r1034235_fix)

Configure the macOS system without ACLs applied to log files with the following command: /bin/chmod -RN /var/audit
