Oracle SBC Security Guide

Session Router

The Session Router is a “pure” SIP session router that can be positioned in either a core network or at

network borders. When installed at a border, the same SBC protections used in peering and access models

can apply. In the network core, the emphasis is on routing and interoperability.

Enterprise Communications Broker

The Enterprise Communications Broker (ECB) should only be deployed within an enterprise core

network, and not on the edge. Instead of perimeter security, the ECB is oriented towards functions such as

dial plan management, centralized session, routing, CAC, load balancing, and interworking.

Realm Design Considerations

As a general rule, separate realms are created for external untrusted traffic and internal trusted traffic.

However, there are many deployment complications that prevent that simple model from being used.

Examples of these might include:

 A mix of user endpoints, gateways, or peer trunks on the untrusted network

 Varying capabilities or incompatibilities of user agents

 Impacts of blocking traffic to one group of users vs. another (i.e. trust low or medium)

 Service level agreements (SLA) that require Call Admission Controls (CAC)
