Denial of Service Issues in Voice Over IP Networks
نویسندگان
چکیده
In this paper we investigate denial of service (DoS) vulnerabilities in Voice over IP (VoIP) systems, focusing on the ITU-T H.323 family of protocols. We provide a simple characterisation of DoS attacks that allows us to readily identify DoS issues in H.323 protocols. We also discuss network layer DoS vulnerabilities that affect VoIP systems. A number of improvements and further research directions are proposed.

متن کاملMAIDS for VoIP: A Mobile Agents-based Intrusion Detection System for Voice over Internet Protocol
Compared to traditional (PSTN) voice networks, a Voice over Internet Protocol network is a convergence of a signaling network and a data network using Internet Protocol (IP). The use of shared media by VoIP systems opens the door to some uncertainty as to the source of a call. While in the traditional voice networks one has to tap into a specific circuit to eavesdrop, in an IP network any equip...

متن کاملQuality of Service for Converged Data and Voice over IP Networks
The datacom and telecom industries are going through a stage of unprecedented change, as new communication ecosystems evolve from isolated, application-specific networks. The industry is moving beyond telecommunications as a utility service, towards a converged voice and data network based on Ethernet protocol and Internet protocol (IP). Quality of service (QoS) has been a feature of voice comm...
متن کاملSecuring Classical IP Over ATM Networks
This paper discusses some security issues of `Classical IP over ATM' networks. After analyzing new threats to IP networks based on ATM, security mechanisms to protect these networks are introduced. The integration of rewalls into ATM networks requires additional considerations. We conclude that careful con guration of ATM switches and ATM services can provide some level of protection against sp...
