Security is a concern for every organization at every level. The introduction of media gateways to handle traditional telephony converted to SIP protocol for VoIP introduces many security management challenges on the data network. If not using media gateways, many organizations are starting to use VoIP providers who carry voice traffic on an IP network connection using the SIP protocol and connect networks using SIP trunking. The widespread adoption of SIP opens potential threats exposing the vulnerabilities of the protocol.

This SIP Architecture and Security Training course will help you understand the issues of network security as they relate to the use of the SIP protocol. We will examine the security vulnerabilities of the protocol as well as each component in a SIP design for a comprehensive review of SIP security issues. We will conclude with a discussion of the policies and procedures that enhance SIP security.
