Check Text ( C-90837r3_chk )
Check the domain name for NIS maps using command: # domainname If no ouput is returned or the name returned is simple to guess, such as the organization name, building, or room name, etc., this is a finding.

Fix Text (F-97881r1_fix)
Change the NIS domain name to a value difficult to guess. Consult vendor documentation for the required procedure.
