Title

The macOS system must configure Apple System Log files to be owned by root and group to wheel. (Cat II impact)

The Apple System Logs (ASL) must be owned by root. ASL logs contain sensitive data about the system and users. If ASL log files are set to only be readable and writable by system administrators, the risk is mitigated. Satisfies: SRG-OS-000205-GPOS-00083,SRG-OS-000206-GPOS-00084
