| Abstract | This paper deals with VoIP communication security and various techniques of VoIP attacks. We divided these threats in several categories according to their specific behaviour and their impact on the affected system. We also tried to find effective methods to prevent or mitigate these attacks. We focused our work on Spam over Internet Telephony (SPIT) as a real threat for the future. We have developed both a tool generating SPIT attacks and AntiSPIT tool defending communication systems against SPIT attacks. AntiSPIT represents an effective protection based on statistical blacklist and works without participation of the called party which is a significant advantage. |
