Abstract

The invention provides a method, device and system for detecting the safety of terminal source codes. The method comprises following steps: obtaining source codes to be detected, performing morphology and grammar analysis on the source codes to be detected and converting the source codes to be detected into a control flow chart; according to a preset defect rule set, extracting defect point set of the preset defect from the control chart and establishing a program dependence chart for defect point of each preset defect; traversing the program dependence chart of defect point of each preset defect, determining that when unpurified data polluted points exist in the program dependence chart, further regarding the unpurified data polluted points as potential defect points. By means of the method, automatic analysis on source codes to be detected is fulfilled to detect existing and potential safety problems of application systems; the defect analysis false report rate is effectively reduced and the detection efficiency is increased.

Description

technical field [0001] The invention relates to the field of Internet security, in particular to a method, device and system for detecting terminal source code security. Background technique [0002] There may be security flaws (loopholes) in many places in the application system software. Code review is to conduct a comprehensive inspection of the source code of the application system, so as to realize the detection of the security of the application system. Existing solutions mainly use Fortify and Coverity to analyze source code defects through source code services to ensure the legal compliance of each online code. However, Fortify and Coverity have a high rate of false positives and false negatives, low detection efficiency, and frequent crashes during scanning. Contents of the invention [0003] In order to realize the automatic analysis of the source code to be detected, discover the existing and potential security problems of the application system, effectively re...
