Servlet interceptor-based security protection method

Abstract

The invention discloses a Servlet interceptor-based security protection method, which is characterized by comprising the following steps of: constructing an interceptor; the configuration server side obtains an object accessing the context information; accumulatively calculating and comparing abuse detection index items; generating a decryption key based on the user name and the access time and returning the decryption key to the browser side; comparing the unforbidden key input by the user with the unforbidden key in the interceptor; intercepting and acquiring different types of request data by each interceptor, and executing blacklist and whitelist verification; and calling a component of an attack detection method preset in the interceptor, and detecting whether attack data exists in the user input data and the system output data. The effects of identifying different levels of security problems, executing different degrees of monitoring processing, realizing graded prevention and control, reducing manual monitoring and processing of vulnerability problems, and more importantly, improving the coverage of security prevention and control, and finally improving the prevention and control efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of system defense, and in particular relates to a method of security protection based on a Servlet interceptor. Background technique [0002] Since the birth of JavaWeb technology, there have been a large number of Java server-side webpages on the Internet, but there are still quite a few websites that are vulnerable to hackers. Criminals such as hackers will use elements, scripts and loopholes in web pages to threaten the security of the Internet and computers. On the one hand, hackers invading the website will cause the website to fail to open and the server to go down; on the other hand, they will use loopholes and weak points to obtain server permissions. Preventing hacker attacks is a long-term job, and web page defense from hackers often requires senior development engineers to spend a lot of time designing a set of detection, monitoring and statistical methods. [0003] There are already methods on ...

Problems solved by technology

However, the existing technology only pays attention to the security protection of a specific function, but ignores that the security protection should cover the input port and output port of the entire application. The lack of perfect work will undoubtedly increase the time of developers and increase the repetition of code; In addition, only a certain type of entry whitelist can be restricted, and a function or a parameter level cannot correspond to a type of blacklist and whitelist, which also brings higher difficulty and more loopholes to security protection
