Title

AIX system files, programs, and directories must be group-owned by a system group. (Cat II impact)

Discussion

Restricting permissions will protect the files from unauthorized modification.

Check Content

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

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.
