The AIX /etc/syslog.conf file must be group-owned by system.

Unauthorized group ownership of the /etc/syslog.conf file can lead to the ability for a malicious actor to alter or disrupt system logging activities. This can aid the malicious actor in avoiding detection and further their ability to conduct malicious activities on the system.

Check the group ownership of /etc/syslog.conf using command: # ls -al /etc/syslog.conf

The above command should yield the following output: -rw-r----- 1 root system 993 Mar 11 07:04 /etc/syslog.conf

If the file is not group-owned by system, this is a finding.

Change the group ownership of the file to system using command: # chgrp system /etc/syslog.conf
