Voice over IP Security

Course Description

Voice over IP (VoIP) systems are vulnerable to the same threats as data networks, including viruses, theft, spam, fraud, privacy invasion, and denial of service attacks. In Voice over IP Security, you'll learn to counter those threats and attacks. You will learn to assess the security of VoIP telephony implementations using a variety of techniques, and you'll examine VoIP security at the raw protocol level, concentrating on attack methodologies that are used against the most popular VoIP protocols. Further, you will explore the architecture of VoIP threats and attacks, and you'll learn their countermeasures in intense hands-on labs.
