Check: GEN001320

Solaris 10 X86 STIG: GEN001320 (in versions v2 r4 through v1 r17)

Title

NIS/NIS+/yp files must be owned by root, sys, or bin. (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

Perform the following to check NIS file ownership. # ls -lRa /usr/lib/netsvc/yp /var/yp If the file ownership is not root, sys, or bin, this is a finding.

Fix Text

Change the ownership of NIS/NIS+/yp files to root, bin, or sys. Procedure: # chown -R root /usr/lib/netsvc/yp /var/yp
