            Abstract : 
With the development of VoIP (Voice over IP) service, new security threats are expected to be appeared. However, existing IP network security solutions can not detect new VoIP specified network threats because they can not reflect characteristics of VoIP. In this paper, we propose a novel system that can monitor VoIP service and detect VoIP network threats practically. The proposed system collects attributes of VoIP traffic based on NetFlow, and executes monitoring and detecting based on statistic and behavior.
