Problems solved by technology

Program slicing can also be divided into static slicing and dynamic slicing methods: static slicing is only used in static programs, and dynamic slicing considers the impact of input values, making it easier to analyze slices, but there are limitations in effectiveness

Embodiment Construction

[0047] The Web service safety analysis method in the present invention includes a vulnerability classification module, a code analysis module, a slicing module, a vulnerability repair module, a service publishing module and a service testing module. figure 1 An overall flow framework of the platform of the present invention is given, and the work flow of each module is described. The following content is a detailed description of the implementation of each module in the present invention.

[0048] 1. Vulnerability classification module

[0049] In the source code of the Web service, there are more or less private variables related to the storage service. If these variables are modified maliciously, some serious consequences may be caused. Therefore, in addition to the developer or manager of the Web service, Other personnel are not authorized to modify these variables. In the present invention, we refer to these variables as key information. There may be many methods in the...

Abstract

The invention provides a web service security analysis method based on a program slicing technique. Starting from key information in a Java source code, the method mainly researches on web services developed based on Java, and vulnerabilities in the Java source code include explicit vulnerabilities and implicit vulnerabilities. For the explicit vulnerabilities, the source code can be analyzed and extracted through traditional statement-level slices to obtain an explicit vulnerability analysis result. For the implicit vulnerabilities, dependency of methods in the source code is analyzed first to generate a method dependency graph, and method-level slices are used to slice the method dependency graph to obtain an implicit vulnerability analysis result. According to analysis on the explicit and implicit vulnerabilities, a vulnerability fixing module is used to fix the vulnerabilities and a service issuing module is used to issue fixed web services.

Description

technical field [0001] The invention provides a web service security analysis scheme based on program slicing technology, which mainly analyzes possible security loopholes in the source code of the web service developed by Java language, and repairs the loopholes, belonging to the field of web service security. Background technique [0002] With the rapid development of the Internet, a large number of network application architectures have emerged, which can be mainly divided into pure Web application of B / S (Browser / Server) structure and distributed application of traditional desktop programs. These systems have been widely used at present, and have achieved greater success. Web services make application integration faster, easier, and cheaper than ever before. Web services are integrated at higher layers in the protocol stack, which can realize loose integration of business functions. Businesses can be connected through the Web between many enterprises and within enterpr...
