Discussion

Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Typically, devices can be identified by MAC or IP address, but certificates provide a greater level of security. Identification of devices works with registration of devices as part of a defense in depth approach to Voice Video networks. Registration is the process of authorizing endpoints to communicate with the session manager. Registration occurs with the SIP server in VoIP systems and with a gatekeeper in H.323 systems. Without enforcing registration, an adversary could impersonate a legitimate device on the Voice Video network.
