Nutanix VMM must be configured to remove ypserv.

It is detrimental for VMMs to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

VMMs can provide a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).

1. Confirm Nutanix AOS is configured to disable nonessential capabilities using the following command.

$ sudo yum list installed ypserv

If the "ypserv" package is installed, this is a finding.

Remove any finding using the following command.

$ sudo yum remove ypserv
