Oracle SBC Security Guide

Part 1: Overview

Product Overview

The Oracle Session Border Controller (SBC) family of products are designed to increase security when

deploying Voice over IP (VoIP) or Unified Communications (UC) solutions. Properly configured,

Oracle’s SBC family helps protect IT assets, safeguard confidential information, and mitigate risks—all

while ensuring the high service levels which users expect from the corporate phone system and the public

telephone network.

Installed at the network perimeter, the SBC family of products provides a demarcation and enforcement

point for the UC network. Its primary security functions include:

 Overload protection to prevent DoS attacks and registration floods

 Access control to inhibit toll fraud and service theft

 Topology hiding to counter topology discovery through reconnaissance scans

 Encryption and authentication to ensure privacy and prevent loss of confidential information

 Protocol validation to combat fuzzing and other types of malicious attacks

Net-SAFE Security Framework

The Oracle Net-SAFE™ security framework addresses the unique security challenges of delivering SIP-

based interactive IP communications over the Internet. The Net-SAFE framework includes advanced

security features, a highly-scalable architecture, and comprehensive monitoring and reporting capabilities.

The framework reduces risk in UC services and applications by ensuring confidentiality, integrity and

availability.

Net-SAFE goals

 Protect the SBC: The first line of defense at the border is the SBC, so it needs to be secure and

resistant to attacks and overload.

 Protect the infrastructure: The infrastructure includes the customer’s network of multimedia

equipment (soft switches, application servers, SIP proxies, MGCP call agents, H.323 gatekeepers,

gateways, etc.).

 Protect the service: Preventing attacks is not enough. UC services that generate revenue need to

remain in service.

Net-SAFE Requirements

The Net-SAFE framework identifies the requirements that an SBC must satisfy to meet the goals of the

framework and provide confidentiality integrity, and availability.
