为了评估复杂系统的安全风险,基于已有的风险评估算法,在结合面向对象知识处理系统的基础上,设计研发一套简捷、使用方便的基于知识的复杂系统风险评估专家系统。对典型复杂系统进行风险评估的结果证明:该系统能够用于现场收集复杂系统数据并且对复杂系统的整体风险进行自动评估,能够指导风险评估分析员对复杂系统中的资产结点制定出合理的安全保护策略,比传统的专家人工分析具有更强的客观性与准确性。
In order to evaluate the security risks of complex systems, based on the existing risk assessment algorithms, this paper designs and develops a simple and easy-to-use knowledge-based expert system for risk assessment of complex systems based on object-oriented knowledge processing system. The results of risk assessment of typical complex systems demonstrate that the system can be used to collect complex system data in the field and automatically evaluate the overall risk of complex systems and guide the risk assessment analyst to make reasonable assessment of asset nodes in complex systems Security strategy, than the traditional manual expert analysis has more objectivity and accuracy.
