Discussion

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

Check Content

Verify the macOS system is configured with Apple System Log files owned by root and group to wheel with the following command: 

/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/wc -l | /usr/bin/tr -d ' '

If the result is not "0", this is a finding.

Fix Text

Configure the macOS system with Apple System Log files owned by root and group to wheel with the following command:

/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}')
