目前,对商业服务器攻击方式主要有两种,包括拒绝服务(DoS)攻击和分布式拒绝服务(DDoS)攻击。这种攻击类型属于命中-运行类型,DoS/DDoS攻击因为不够灵敏而不能绕过防火墙等防御,即DoS/DDoS攻击向受害主机发送大量看似合法的网络包,从而造成网络阻塞或服务器资源耗尽而导致拒绝服务。虽然数据没有被损坏,但是服务器最终被摧毁,并且还会引发一系列其他的问题,对于一个电子商务服务器,其最重要的为服务器的停机时间。研究对分布式拒绝服务(DDoS)防御原则。
At present, there are mainly two kinds of commercial server attacks, including DoS attacks and DDoS attacks. This type of attack is a hit-and-run type. DoS / DDoS attacks can not bypass defenses such as firewalls because they are insensitive. That is, DoS / DDoS attacks send a large number of seemingly legitimate network packets to victim hosts, causing network congestion or server resource consumption As a result, denial of service. Although the data was not corrupted, the server was eventually destroyed and a number of other issues were raised that led to server downtime for an e-commerce server. Research on Distributed Denial of Service (DDoS) defense principles.
