Check Text ( C-90627r1_chk )
Check the group ownership of system files, programs, and directories run the following command:
# ls -lLa /etc /bin /usr/bin /usr/lbin /usr/ucb /sbin /usr/sbin

If any system file, program, or directory is not group-owned by a system group, this is a finding.

Note: For this check, the system-provided "ipsec" group is also acceptable.
Fix Text (F-97671r1_fix)
Change the group owner of system files to a system group by running the following command:
# chgrp sys /path/to/system/file

Note: System groups other than "sys" may be used.
