【摘要】 随着信息系统的迅猛发展和不断应用,信息安全成为人们研究的重点。文章首先分析了通信安全、计算机安全和信息系统安全的特点及发展过程。从系统工程的角度,提出了信息系统安全三维体系结构模型,从技术维、时间维和管理维对信息系统的安全进行了描述,指出了该三维模型和网络七层协议的关系。该模型对信息系统安全保密研究具有一定的理论指导意义。更多还原

【Abstract】 With the rapid development and wide application of information system,information security becomes one of the re-search hotspots.In this paper,a three-dimension model of in-formation system security,which is technology dimension,time dimension and management dimension,is proposed.This paper indicates the relationship between this three-dimension model and seven levels protocol of OSI/R.This model emphasizes that network security is important,the management is first in infor-mation system security,and human is key of security manage-ment.It is an important role to research information system se-curity.更多还原
