计算机安全面临常见问题及防御对策探讨

A Brief Review on Current Computer Security Problems and Defense Strategies

文章简介了计算机安全的基本概念和流行的国际标准,一方面从硬件角度探讨了电磁攻击和电磁泄露带来的计算机安全问题,另一方面也从软件角度归纳了病毒、网络攻击、非法入侵等各种造成计算机安全问题的各种原因,描述了通过电磁屏蔽加固技术、加密技术和认证技术等方法提高计算机安全的措施。

Some important concepts and general international standards about computer security are introduced. The computer security problems caused by possible electromagnetic attack and electromagnetic leak are analyzed from the view of hardware. The software reasons to break computer security are demonstrated by some cases with virus, network attack and illegal intrusion. Some strategies and technologies are presented to enhance computer security system by such methods as electromagnetic shield reinforcement, encryption and security certifications.
