All system start-up files must be group-owned by root, sys, or bin.

If system start-up files do not have a group owner of root or a system group, the files may be modified by malicious users or intruders.

Check run control scripts' group ownership.

Procedure: # ls -lL /etc/rc* /etc/init.d

If any run control script is not group-owned by root, sys, or bin, this is a finding.

Change the group ownership of the run control script(s) with incorrect group ownership.

Procedure:

# chgrp root <run control script>
