Title

NIS/NIS+/yp files must be group-owned by root, sys, bin, other, or system. (Cat II impact)

Discussion

NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

Check Content

Check the group ownership of the NIS/NIS+/yp files. Procedure: # ls -lL <NIS file> If any such file is not group-owned by root, sys, bin, other, or system, this is a finding.

Fix Text

Change the group owner of the NIS files to root, sys, bin, other, or system. Procedure: # chgrp root <filename>
