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

Perform the following to check NIS file ownership:

# ls -la /var/yp/*

If the NIS file ownership is not "root", sys, or bin, this is a finding.

Fix Text

Change the ownership of NIS/NIS+/yp files to "root", "sys", "bin", or "system". Consult vendor documentation to determine the location of the files:

# chown root <filename>
