摘要
给出了代码复用攻击挟持控制流的过程,介绍了代码复用攻击防御机制研究现状。重点论述了基于硬件的防御机制,包括基于硬件的存储安全、代码指针完整性、攻击特征检查、控制流完整性、数据执行保护与隔离技术。讨论了基于硬件的防御机制存在的问题、优势及硬件与软件的关系。展望了基于硬件的代码复用攻击防御机制的发展方向:基于硬件的代码指针完整性有望成为防止控制流挟持攻击的有效手段,针对非控制数据的攻击与防御有可能成为新的研究热点,支持可配置的硬件防御架构是硬件防御的重要趋势之一。
The process of control-flow hijacking in code-reuse attacks is described,and the current research status of the code reuse attack defense mechanism is introduced. The main problems of the hardware based defense mechanisms are discussed,including memory safety,code pointer integrity,malware detection based on attacks＇ features,control flow integrity,data execution prevention,and isolation technology. The disadvantages and advantages of hardware defense mechanisms,and the relationship between hardware and software are also analyzed. The future research directions of hardware based security mechanisms are predicted： hardware based code pointer integrity is the most promising technology to prevent all control-flow hijacks; non-control data attacks and their defense will replace code-reuse attacks as a new research topic. The research also points out the necessity of researching configurable hardware based defense architectures.
