The macOS system must be configured so that log files do not contain access control lists (ACLs).

An XCCDF Rule

Description

<VulnDiscussion>The audit service must be configured to create log files with the correct permissions 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.
