SIP Architecture and Security Training

SIP Architecture and Security Training Course with Hands-On Exercises (Online, Onsite and Classroom Live)

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.

SIP Architecture and Security TrainingDuration: 3 days

  • We can adapt this SIP Architecture and Security Training course to your group’s background and work requirements at little to no added cost.
  • If you are familiar with some aspects of this SIP Architecture and Security Training course, we can omit or shorten their discussion
  • We can adjust the emphasis placed on the various topics or build the SIP Architecture and Security Course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the SIP Architecture and Security course in manner understandable to lay audiences.
