Title

The macOS system must configure the audit log folders group to wheel.

Control

Verify the macOS system is configured with audit log folders group-owned by wheel with the following command: /bin/ls -dn $(/usr/bin/grep '^dir' /etc/security/audit_control | /usr/bin/awk -F: '{print $2}') | /usr/bin/awk '{print $4}' If the result is not "0", this is a finding.

Discussion

Audit log files must have the group set to wheel. The audit service must be configured to create log files with the correct group ownership to prevent normal users from reading audit logs. Audit logs contain sensitive data about the system and users. If log files are set to be readable and writable only by system administrators, the risk is mitigated.
