Considering the growing number of organizations that has adopted VoIP technology in their phone systems and the increase of security incidents involving these infrastructures, this course aims to familiarize students with major security concerns related to VoIP infrastructures and the major threats that these infrastructures are exposed, as well as existing mechanisms to make these environments safer.

The course will address techniques used by miscreants ranging from hide and/or change the origin of a call, to problems related to information leakage through the so-called "digital eavesdropping."
