AOSX-15-001014 - The macOS system must be configured with audit log files group-owned by 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 root or administrative users with sudo, the risk is mitigated.
For any log file that returns an incorrect group owner, run the following command: /usr/bin/sudo chgrp wheel [audit log file] [audit log file] is the full path to the log file in question.
