摘要
随着计算机技术的发展和网络性能的提升,分布式拒绝服务攻击已经成为当前网络安全领域一个主要的问题。本文从主机扫描、主机入侵、攻击掩护等方面详细剖析了DDOS的过程,并对包括SYN、ICMP、UDP几种主要的攻击手段进行了分析。最后针对DDOS攻击的特点,在传统熵值入侵检测方案的基础上,提出了一种高效的熵值算法。
With the development of computer teehnology anti network performance of ascension that distnbuted denial of servia.t, attack has become the field of network security is a major problem. This paper from the host scanning, host intru- sion and attack cover etc detailed analyzes the proeess of DDOS, and including SYN, ICMP, UDP several main attack methods are analyzed. Finally, according to the characteristics of DDOS attack, in the traditional entropy value intrusion detection scheme was proposed based on a kind of high efficient entropy algorithm.
