拒绝服务攻击防范技术研究

Survey on Countermeasure Against Denial-of-Service Attacks

拒绝服务攻击对网络构成了巨大的安全威胁.由于网络协议本身并不安全,所以处理拒绝服务攻击是非常困难的.从分析拒绝服务攻击的起因入手,揭示拒绝服务攻击的机制和过程,并对拒绝服务攻击进行归类,总结了防范拒绝服务攻击的措施.

Denial-of-Service （DoS） attacks present a considerable security threat to the intemet. It is increasingly difficult to treat the Denial of Service attacks, because intemet protocol is inherently not secure. In this paper we analyze the causes of DoS attacks,exposes their various mechanisms and proceduresand and summarize the countermeasure of keeping away DoS attacks.
