Threats to voice over IP communications systems

Original language description

This article deals with various techniques of VoIP attacks and VoIP communication security. These threats are divided in several categories according to their specific behaviour and their impact on the affected system. We describe effective methods to prevent or mitigate these attacks. Our work was especially focused on Spam over Internet Telephony (SPIT) as a real threat for the future and we consider spam in IP telephony to be very serious due to situation we face in e-mail communication. We have developed both an AntiSPIT tool defending communication systems against SPIT attacks and a tool generating SPIT attacks. AntiSPIT represents an effective protection based on statistical blacklist and works without participation of the called party which is significant advantage, AntiSPIT was implemented into Asterisk open-source platform and became one way of protection against the voice spam expected in near future.
