Discussion

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 Content

Check run control scripts' group ownership.

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

Alternatively:
# find /etc -name "[SK][0-9]*"|xargs stat -L -c %G:%n|egrep -v "^(root|sys|bin|other):"
If any run control script is not group-owned by root, sys, bin, or other system groups, this is a finding.

Fix Text

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

Procedure:
# chgrp root <run control script>
# find /etc -name "[SK][0-9]*"|xargs stat -L -c %G:%n|egrep -v "^(root|sys|bin|other):"|cut -d: -f2|xargs chgrp root
