伴随着网络通信技术和计算机技术的迅猛发展,基于网络的计算机系统日益庞大,而且组成计算机系统的实体数量和类型、网络结构以及数据信息处理和交流方式等都发生了巨大的变化,构成了1个庞大的复杂系统,因此,如何确保当前计算机系统网络通信的安全已经成为行业内的重要研究课题。本文以此为背景,从基于网络的计算机系统安全模型的相关概念谈起,然后就当前的几种主要计算机系统安全模型进行详细说明,最后就基于网络的计算机系统的安全模型的设计进行研究分析。
With the rapid development of network communication technology and computer technology, network-based computer systems are increasingly large, and the number and type of entities that make up a computer system, the network structure, and the way of data information processing and communication have undergone tremendous changes. Therefore, how to ensure the security of the current computer system network communication has become an important research topic in the industry. Based on this, this paper starts from the related concepts of network-based computer system security model, and then describes several current major computer system security models in detail. Finally, the security model of network-based computer system is studied and analyzed .
