Discussion

The use of hard-to-guess NIS domain names provides additional protection from unauthorized access to the NIS directory information.

Check Content

Check the domain name for NIS maps.

Procedure:
# domainname

If the name returned is simple to guess, such as the organization name, building or room name, etc., this is a finding.

Fix Text

Change the NIS domainname to a value difficult to guess. Consult vendor documentation for the required procedure.
