Problems solved by technology

[0004] Static code detection methods include the popular data flow analysis method and the finite state set method. Among many java static detection tools, PMD and findbugs are mainly aimed at the detection of code quality, and there are few types of security vulnerabilities involved. checkstyle cannot detect security vulnerabilities at all; jslint mainly detects according to several rules about code quality propose

Embodiment Construction

[0023] According to the detection method of the present invention, the scanning process of the above-mentioned source code is specifically as follows: first, the source code is parsed into a standard AST tree, and then data flow and control flow analysis are performed on the AST tree. If our rule is defined as the initial api is execute, Terminate the api as getParameter, then when calling the parser, the specific parsing process is as follows:

[0024] ●First search for the code with the api name execute in the data flow results, and check one by one if you find more than one

[0025] ●Analyze the parameters of execute to get the query

[0026] ●Find the call list of the variable query in the data flow result, and find the definition statement String query=”SELECT*FROM student WHERE owner=”’+userName+”’AND studentname=”’+studentName+””’;

[0027] ●Analyze the definition statement and find that the query is related to the variables userName and studentName

[0028] ●Find the...

Abstract

The method provides a new method for detecting Java source code security loophole caused by insecure input. The method adopts the parsing and data and control flow analysis technology and achieves the purpose of detecting different types of loopholes by calling a security analyzer through security rules. Proved by tests, the method can be used for scanning various engineering source codes developed in java language and achieves higher accuracy rate.

Description

technical field [0001] The invention is used in the field of source code static detection security loopholes, especially for detecting loopholes caused by unsafe input in source codes developed with Java language. Background technique [0002] With the rapid development and continuous growth of China's software market in the past two years, the accompanying software security issues have also attracted more and more people's attention. There are many reasons for software security problems. Due to the tight development time and heavy workload, programmers may ignore code quality and software security-related issues during the development process; at the same time, with the continuous expansion of the software market, the quality of practitioners It is also constantly declining. Because programmers themselves do not have enough understanding of information security and network security, some serious loopholes will also appear during the development process. Based on the above c...
