| 摘 要： | 为了解决目前信息安全风险评估系统中存在的主观性强、静态评估等问题,该文提出了一种基于生物免疫学危险理论的信息安全风险评估模型DT-RA,采用危险信号触发机制,能够应对不断变化的信息系统和网络环境,然后给出了一种基于DT-RA模型的安全事件发生可能性风险的计算方法,最后根据国标计算得出整个信息系统的风险值。本文在假设一定...

| Abstract: | Information security risk assessments,such as subjective and static assessments are improved by an information security risk assessment system based on Biological Immunology Danger Theory.The system uses the danger signal trigger mechanism to deal with mutated information systems and networks.This model is used to calculate the possibility of a security incident.The information system risk is then calculated according to the Chinese standard.Simulations with asset scale,attack priorities and changing attack... |
