Security is a concern for every company at every level. The wide adoption of VoIP and new protocol standards has introduced many new issues. For most enterprises, the adoption of VoIP is a migration path – a fact that contributes to increased complexity for the IT security personal and network administrators. VoIP introduces new systems, vendors, applications, servers, operating systems, and the like. The introduction of media gateways to handle traditional telephony converted to VoIP on the data network introduces security management challenges on the network. If not using media gateways, organizations are adopting VoIP providers that carry traffic on an IP network connection.

This course will help you understand the issues of VoIP security on all levels of the network. We will follow the OSI model to ensure that all levels are covered. We will begin by learning the technical concepts related to network security. We will then study the protocols such as SIP and H.323 on the IP network. We will conclude with a discussion of the policies and procedures that enhance VoIP security
