Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings. Detect and give feedback on the security of the JavaScript code in the website to discover security issues including non-standard JavaScript coding and malicious code in cross-site scripting attacks.

[0039] In order to achieve the above object, the present invention first uses the DLint tool to dynamically discover the non-standard coding of JavaScript, and then uses the open source static code specification detection tool ESLint to detect the branch part of the source code; then uses the static analysis method, according to the characteristics and settings of the JavaScript page threshold to filter out pages with malicious code that may contain cross-site scripting attacks in the source code, and finally use the Jalangi framework to perform dynamic instrumentation on the filtered pages for taint analysis to determine whether the filtered pages contain cross-s...

Abstract

The invention discloses a rule-based JavaScript security testing method. A program analysis method in which static analysis and dynamic analysis are combined is utilized for testing the security problem of a JavaScript code in a website and performing feedback, thereby finding out the security problems which comprise JavaScript coding standardization un-qualification and over-site script attack malicious codes. The method comprises the steps of dynamically finding out a JavaScript coding standardization un-qualification problem by means of a DLint tool, then testing the branched parts of a source code by means of an open-source static code standardization testing tool ESLint; then filtering a page which may contain over-site script attack malicious codes in the source code according to JavaScript page characteristics and a preset threshold according to a static analysis method; and then performing dynamic Instrumentation on the filtered page for performing strain analysis by means of a Jalangi frame, thereby determining whether the filtered page contains an over-site script attack. The rule-based JavaScript security testing method effectively improves testing efficiency for code standardization and malicious codes based on miss rate reduction.

Description

technical field [0001] The invention relates to the field of detection or processing of computer malicious software, in particular to a rule-based JavaScript security detection method. Background technique [0002] With the development of Web2.0 technology, the development of applications using JavaScript continues to accelerate. JavaScript is a web scripting language that has been widely used in web application development. It is often used to add various dynamic functions to web pages to provide users with smoother and more beautiful browsing effects. Usually, JavaScript scripts realize their own functions by embedding them in HTML. [0003] JavaScript is favored by people because of its dynamic interaction capability and good performance on various browsers, but at the same time, it also brings more and more security problems. [0004] Due to its loose coding organization, JavaScript often has the characteristics of non-standard coding, which allows malicious attackers ...
