Fix Recommendation

Configure the Ubuntu operating system to have adm group-own the "/var/log/syslog" file by running the following command:

$ sudo chgrp adm /var/log/syslog

Check Contents

Verify that the Ubuntu operating system configures the "/var/log/syslog" file to be group-owned by adm with the following command:

$ sudo stat -c "%n %G" /var/log/syslog
/var/log/syslog adm

If the "/var/log/syslog" file is not group-owned by adm, this is a finding.
