Title

The macOS system must configure audit log folders to be owned by root. (Cat II impact)

Discussion

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