For any log file that returns an incorrect owner or group value, run the following command:
/usr/bin/sudo chown root:wheel [log file]
[log file] is the full path to the log file in question. If the file is managed by "newsyslog", find the configuration line in the directory "/etc/newsyslog.d/" or the file "/etc/newsyslog.conf" and ensure that the owner:group column is set to "root:wheel" or the appropriate service user account and group.
If the file is managed by "aslmanager", find the configuration line in the directory "/etc/asl/" or the file "/etc/asl.conf" and ensure that "uid" and "gid" options are either not present or are set to a service user account and group respectively.
Log files are controlled by "newsyslog" and "aslmanager".
These commands check for log files that exist on the system and print out the log with corresponding ownership. Run them from inside "/var/log":
/usr/bin/sudo stat -f '%Su:%Sg:%N' $(/usr/bin/grep -v '^#' /etc/newsyslog.conf | awk '{ print $1 }') 2> /dev/null
/usr/bin/sudo stat -f '%Su:%Sg:%N' $(/usr/bin/grep -e '^>' /etc/asl.conf /etc/asl/* | awk '{ print $2 }') 2> /dev/null
If there are any system log files that are not owned by "root" and group-owned by "wheel" or admin, this is a finding.
Service logs may be owned by the service user account or group.
