Abstract

The embodiment of the invention provides an attack detection method and device and a website application level intrusion protection system WAF, the WAF comprises a proxy server, a connector and a matching engine, and the method comprises the steps that the proxy server receives a to-be-detected message and transmits the to-be-detected message to the connector; the connector transmits the message to be detected to the matching engine through a registration interface of the matching engine; and the matching engine performs attack detection on the to-be-detected message and determines a detection result of the to-be-detected message. By applying the technical scheme provided by the embodiment of the invention, the expansibility of the WAF can be improved, and the problem of potential safety hazards in a network caused by flow interruption in attack detection is solved.

Description

technical field [0001] The present application relates to the technical field of network security protection, in particular to an attack detection method and device and a website application-level intrusion prevention system WAF. Background technique [0002] With the development of Internet technology, website (Web) applications are getting more and more attention from business systems. At the same time, web servers with powerful computing power, processing performance and high value have gradually become the main attack targets. [0003] In order to maintain the security of the web server, the currently commonly used website application-level intrusion prevention system (WebApplication Firewall, WAF) is the Nginx-based ModSecurity protection system. In this WAF, the Nginx proxy server is connected to the ModSecurity detection engine, which has a built-in core rule set. The Nginx proxy server forwards the received packet to the ModSecurity detection engine. The ModSecurit...
