The Enterprise Voice, Video, and Messaging Endpoint must be configured to prevent the configuration or display of configuration settings without the use of a PIN or password.

Many Enterprise Voice, Video, and Messaging Endpoints can set or display configuration settings in the instrument itself. This presents a risk if a user obtains information such as the IP addresses and URLs of system components. This obtained information could be used to facilitate an attack on the system. Therefore, these devices should be considered a target to be defended against such individuals that would collect voice network information for illicit purposes. To mitigate information gathering by the adversaries, measures must be taken to protect this information.
