摘　　要：SIP协议是NGN中的重要协议之一,它在Internet环境下建立并管理会话,正以迅猛的速度改变当今企业及各种机构的沟通方式,因此对SIP协议安全性的研究也就显得格外重要。尽管多年来全球无数网络安全专家都在潜心研究DoS攻击的解决办法,但到目前为止收效不大,因为DoS攻击利用了协议本身的弱点。研究了针对VoIP环境下的DoS攻击,在简单介绍SIP协议和DoS攻击的基础上,详细地描述了基于SIP的VoIP网络环境中的DoS攻击的多种攻击类型,并给出针对这些攻击的网络安全维护对策。SIP （session initiation protocol） is one of the important protocols in next generation network. It aims to establish and manage session and is rapidly changing today＇s enterprises and institutions by communication. So SIP security research will be particularly important, Although for many years the whole world innumerable network security experts all have been exerting oneself study the DoS attack the solution, but the result is not so satisfying, this is because the DoS attack has used the weakness of protocol. Through the thorough research in DoS under the environment of VoIP, the S/P and DoS attack are introduced simply and then a detailed description of DoS attacks on SIP-based VoIP network is given, at last security recommendations are given according to these attacks.
