Check Text ( C-16616r294705_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-16614r294706_fix)
Change the NIS domain name to a value difficult to guess. Consult vendor documentation for the required procedure.
