基于XML的软件安全静态检测方法研究

安全关键软件设计使用的C/C++语言含有大量未定义行为，使用不当可能产生重大安全隐患。软件静态检测是从软件代码和结构中找出安全缺陷的重要手段。从安全规则的角度，提出了基于XML（eXtensible Markup Language）中间模型的静态检测方法。该方法将C/C++源代码解释为XML中间模型，将安全规则转化为缺陷模式，利用Xquery查询表达式对软件安全缺陷进行定位。基于该方法的原型系统检验结果表明：该方法能够有效地检测出违反安全规则的软件缺陷，并具有安全规则可定制的特点。

Research on static analysis method for software security based on XML

Fatal security vulnerabilities are caused by undefined behaviors of C/C＋＋ language used in Safety-Critical software design.Software static analysis is an important technique for identifying security vulnerabilities from software code and structure.The static analysis method based on XML intermediate model is proposed in term of safety rules.The source code is interpreted as XML intermediate model,while safety rules are translated into vulnerabilities pattern,and Xquery expression is used to locate security vulnerabilities by this method.The experimental result of a prototype system based on this method shows that this method can effectively detect the software vulnerabilities in violation of safety rules and has the advantage of supporting customization of safety rules.
