针对SIP的DoS攻击与防御研究

Research on DOS Attack and Defense of SIP

拒绝服务攻击(DoS)由于其实施相对简单,隐蔽性较高,目前已成为互联网上最大威胁。随着互联网的迅猛发展和广泛应用,作为NGN核心的会话初始协议(SIP)在网络中的运用越来越广泛,其安全问题也越来越受到关注。论文对于针对SIP的拒绝服务攻击进行研究和分析,并提出应对攻击的防御方案。

DoS/DDoS have become the biggest threat to the Internet, because the attacker could easily launch attack and hide themselves. With the fast development of the Internet, the core protocol of NGN-Session Initial Protocol（SIP） has become more and more popular, and security problem of SIP attracted more and more attention. This paper focuses on the research and analysis of DOS attack against SIP, and gives security solutions for mitigating the DOS attack.
