摘要
企业需要正视信息系统的安全问题并对信息系统安全性进行科学合理的评估。依据信息系统的层次性,从系统的物理层、网络层、操作系统层、应用层和管理层五个层次对系统的安全性进行了评估,建立了信息系统安全性评估的多级可拓模型,并通过算法的演示,说明其实用性。
Enterprises need to take a new look at information system security issues, and conduct a scientific and rational assessment on the security of the information system. Based on different levels of information system, evaluations on its security have been carried out from the system＇s physical aspect, network, the operating system, application and the management level, and a multi-level extension model of information system security assessment is also established. The practicability of the model is further illustrated and tested by the demonstration of the algorithm.
