Abstract

The invention provides a Web application security protection method and a WAF system. The WAF system comprises a Web server and an nginx server. The method comprises the following steps of building the Web server by adopting a python tornado framework; detecting whether the access request transmitted by the nginx server is an abnormal request or not by utilizing the Web server to obtain a detection result; using the Web server to send a detection result to the lua script in the nginx server; reading a detection result of the input lua script by using the nginx server to determine whether the access request is an abnormal request or not; if the access request is an abnormal request, intercepting the access request by using a lua script; and otherwise, forwarding the access request to the corresponding service line source station by using the nginx server. According to the WAF system, when Web application security protection is realized, excessive server resources are not occupied, and the occupancy rate of the WAF system on the server resources is reduced.

Description

Technical field [0001] The invention relates to the technical field of network application security, and more specifically, to a web application security protection method and a web application firewall system. Background technique [0002] WAF (Web Application Firewall, Web Application Firewall) system is mainly used to achieve enhanced protection against Web-specific intrusion methods, such as DDOS protection, SQL injection, XML injection, XSS, etc. [0003] The existing WAF system occupies a large amount of memory, it consumes more time to parse the request, and has a greater impact on the delay-sensitive business. Especially when processing a large number of real-time requests, in order to ensure the accuracy and real-time of request detection, it usually needs to consume a lot of server resources to provide support, resulting in a high occupancy rate of server resources by the WAF system, which affects other The normal use of server resources by the business. [0004] Therefor...
