Network Layer Security

Network Layer Security

The on-premises, IMS hosted, and SP hosted networks have implemented different network layer security policies.

  • On-premises network:
    • The endpoint, SMC2.0, and MCU are deployed in the trusted zone, isolated from the Demilitarized Zone (DMZ) and the untrusted zone. Firewalls are deployed for security domain division and access control.
    • Terminals (such as TE Desktop and TE Mobile) in the untrusted zone communicate with NEs in the trusted zone through the Session Border Controller (SBC) or Switch Center (SC) in the DMZ.
  • IMS hosted and SP hosted networks:
    • The endpoint is deployed in the untrusted zone, isolated from the DMZ and the trusted zone through the SBC or the extranet firewall.
    • If the DMZ is deployed, install the SBC, SC, USM Proxy, and MediaX Proxy in the DMZ for endpoint connections.
    • If no DMZ is deployed, the endpoint connects to the trusted zone through the SBC. The USM Proxy and MediaX Proxy are not required.
    • On network borders between the DMZ and the trusted and untrusted zones, firewalls are deployed to implement security domain division and access control.

The endpoint provides the cloud hall function, through which users can easily place calls to the cloud-based videoconferencing platform. Currently, the endpoint supports only cloud halls with fixed IP addresses. Table 3-6 lists the currently supported cloud halls.
