摘要

目前，IP语音(VoIP)电话网络连接到经典的公共交换电话网络(pstn)。可以从VoIP对等点向PSTN公共服务应答点(psap)进行紧急呼叫。通过IP网络和pstn的连接，PSAP可能成为新的、更强大的拒绝服务(DoS)攻击的受害者。本文描述了PSAP目前和未来的体系结构。通过对PSAP的测量，揭示了PSAP攻击检测面临的挑战。进一步指出了第一解并对其进行了评价

Present and future challenges concerning DoS-attacks against PSAPs in VoIP networks

Nowadays, voice over IP (VoIP) telephony networks are connected to classic public switched telephony networks (PSTNs). Emergency calls from VoIP peers to PSTN public service answering points (PSAPs) are possible. Through the connection of IP networks and PSTNs the PSAP may be a victim of new, more powerful denial of service (DoS) attacks. This paper describes the present and future architecture of a PSAP. Based on measurements at a PSAP the challenge of attack detection at the PSAP is revealed. Furthermore, first solutions are pointed out and evaluated
