摘  要:我国的军工研究院一直面临着各方敌对势力带来的威胁与安全风险,为应对安全保密保卫形势,加强研究院安防系统的建设十分重要。为定量分析研究院安防系统在拦截入侵行为时的防护薄弱路径,基于 EASI 模型的计算原理,建立了分析平台,通过输入安防系统各保护单元的探测、延迟、响应数据,即可得出所有路径的截住概率 PI,同时分析最薄弱路径的关键影响因素对路径 PI 结果的敏感性,针对性地提出改进措施,增加安防系统的防护能力。

Abstract: China’s military industry research institutes have been facing threats and security risks brought by various hostile forces. In order to cope with the situation of security, confidentiality and defence, it is very important to strengthen the construction of the research institutes security system. In order to quantitatively analyze the weak protection path of the research institute security system when it intercepts intrusions, an analysis platform is established based on the calculation principle of EASI model. By inputting the detection, delay and response data of each protection unit of the security system, the intercept probability PI of all paths can be obtained. At the same time, the sensitivity of the key influencing factors of the weakest path to the path PI results is analyzed, and targeted improvement measures are proposed to increase the protection capability of the security system.

Keywords: security system; EASI model; intercept intrusion; sensitivity analysis
