Course Overview

Course in a Nutshell

Security is a concern for every company 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. The widespread adoption of SIP opens potential threats exposing the vulnerabilities of the protocol.

This 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.


Customize It!

Are you an engineer, technician, network administrator, decision maker, procurement specialist, or marketing/sales professional looking for SIP security training from your own unique perspective?

We can customize this course, usually at little to no additional cost, to a variety of audiences, orientations (business versus technical), tech level (high-level overview versus in-depth technical detail), and industries (commercial, government agencies, or military).
