计算机主机信息安全问题研究

Mainframe Computer Information Security Research

随着信息技术的迅速发展,信息安全问题越来越受到人们重视。从组成信息服务的层次来看,信息系统一般是由主机、服务器及网络三个层次组成。在这三个层次中,人们往往把过多的注意力放在对服务器和网络的保护和管理上,而忽略了对终端主机的保护和管理,这是不合理的。在信息系统中,主机是人们日常工作的主要平台,用户在主机上进行各种事务处理,存放重要信息,同时绝大多数攻击事件也是从主机发起的。因此,主机的安全保护在系统安全体系结构中居于极其重要的位置。解决安全问题应从主机安全问题入手,增强主机自身的安全性,本文通过分析主机系统结构,提供了一套针对主机安全问题的解决方案。

With the rapid development of information technology, information security has received increasing attention. From the level of information services, information systems are generally from the host, servers and network composed of three levels. In this three levels, people tend to focus too much on the server and network protection and management, the neglect of the host - to - end protection and management, this is unreasonable. In the information system, the host is the day - to - day work of the main platform, users in a variety of services on the mainframe processing, storage of important information, while the vast majority of attacks are launched from the host. Therefore, host of security protection in the system security architecture of living in an extremely important position. Host address security issues should start with security issues, enhance the security of their host, the paper through the analysis of the host system structure, provides a set of host security solutions.
