Check Text ( C-16466r294255_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-16464r294256_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.
