NIS maps must be protected through hard-to-guess domain names on AIX.

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

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.

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