Details

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.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Run the following bash code

/usr/sbin/chown root:wheel $(/usr/bin/stat -f '%Su:%Sg:%N' $(/usr/bin/grep -e '^>' /etc/asl.conf /etc/asl/* | /usr/bin/awk '{ print $2 }') 2> /dev/null | /usr/bin/awk '!/^root:wheel:/{print $1}' | /usr/bin/awk -F":" '!/^root:wheel:/{print $3}')
