摘要
随着计算机技术的迅速发展,DoS攻击成为主要的网络安全隐患。从分析主机资源耗损入手,提出了一种防御DoS攻击的一种算法。该算法通过分析系统CPU占用率来判断是否发生DoS攻击和进行DoS攻击的IP数据包,并进一步取缔非法占用的系统资源来保护主机能够正常工作。
With the development of computer science, DoS attack had become a ahidden danger in network. An new arithmetic is proposed to protect the resource of host computer. The arithmetic based on rate of CPU to judge if occurring DoS attack and IP data marker, so arithmetic terminate illegitimate impropriating to protect host computer.
