Description
The Apple System Logs must be owned by root. ASLs contain sensitive data about the system and users. Setting ASL files to be readable and writable only by system administrators mitigates the risk. Satisfies: SRG-OS-000205-GPOS-00083, SRG-OS-000206-GPOS-00084
ℹ️ Check
Verify the macOS system is configured with ASL 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
Configure the macOS system with ASL 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}')
