Embodiment Construction

[0061] The embodiment of the present invention provides a web anti-injection device, refer to figure 1 , in a preferred embodiment, the device includes:

[0062] The binding module 10 is used to bind the pages and variables of the Web application to form an association between the pages, variables and operations; because in the entire Web application, the effects of different variables on different pages are different, some are Query the entrance of the database, and some are just common operations such as display and printing. In order to distinguish the different functions of different parameters, the embodiment of the present invention binds variables and pages through the binding module 10 to establish an association of information such as variables, pages, and operation types. After binding, the variable is not just an isolated parameter, but is associated with the page. After binding, the variable has the property of the page, which can better distinguish the function ...

Abstract

The invention discloses a Web anti-injection method. The web anti-injection method comprises the step A of binding Web application pages and variables, and forming incidence relations among the pages, the variables and operation; a step B of receiving legal data used for training the variables and input by users, and performing calculation and statistic treatment on an information distance of the legal data; a step C of building a recognition model according to statistical information of the information distance of the legal data so as to judge whether input data are legal. The invention further provides a Web anti-injection device corresponding to the method and Web anti-injection equipment with the Web anti-injection device. According to the Web anti-injection method, device and equipment, unknown attack can be defended dynamically, zero-day attack can be resisted, and attackers cannot perform spoofing attack.

Description

technical field [0001] The present invention relates to the field of Internet technology applications, and more specifically, to a method, device and equipment for preventing web injection. Background technique [0002] Web security is the core content of today's network security and information security. According to statistics, the most serious web security threats at present are cross-site attacks, SQL (Structured Query Language, Structured Query Language) injection, DDoS (Distributed Denial of service, distributed denial of service) attacks, and zero-day attacks. Database attacks are as high as 44%, and SQL injection is one of the most important attack methods in database attacks. [0003] At present, most of the industry's defense methods against database attacks focus on SQL auditing. In terms of SQL auditing, it can be defended through machine learning, syntax analysis, or business analysis. There are few relatively well-formed solutions in terms of Web anti-inject...
