Abstract

Embodiments of the invention disclose detection method and device of an attack for a Web server group, and the method and device are used to respond to a rapidly changing Web attack. The method comprises obtaining a potential attack set which is determined according to request character strings of Web requests sent to the Web server group in a preset period, performing cluster analysis on the request character strings, diving the request character strings to potential attack clusters according to a result of the cluster analysis, calculating a filtering factor, which is a ratio of the number of request character strings in the potential attach clusters to the number of Web servers corresponding to the request character strings, lurked in each potential attack cluster, and determining whether an attack exists according to the filtering factor. The rapidly changing Web attack can be responded.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for detecting an attack on a Web server group. Background technique [0002] With the birth of a series of new Internet products such as Web2.0, social network, and Weibo, Internet applications based on the Web environment are becoming more and more extensive, and various applications in the process of enterprise informatization are set up on the Web platform. [0003] The rapid development of web services has also aroused greater interest from attackers, and they adopt a dragnet-style web vulnerability scanning method to obtain the maximum attack benefits. When a new vulnerability appears, attackers often use writing tools to scan the Internet to maximize the discovery of vulnerable Web servers and attack them. [0004] However, the commonly used defense methods against Web attacks in the prior art are generally protection against certain types of attacks, such a...
