摘要:
计算机和网络安全是个至关重要的话题，但是仅仅靠防护系统来保存网民、企业和政府机构的数据是远远不够的。如路由器、DNS服务器和交换机等基础设施能够很好地将网络连接在一起，否则计算机不可能进行可靠的通信。鉴于网络安全的重要性，引出了几个问题：要用怎样的基础设施来应对怎样的网络安全威胁，当然首先要考虑的是成本。但是在所有这些问题之前要知道如何去定义一个安全的系统。什么是安全？每个人都能说出点什么，但很少有人能够对安全做出精确的定义。文中将以独特的视角来定义网络安全，因为这关系到一个国家、一个组织甚至是个人用户的现在和将来
Abstract:
Computer and network security are critical issues. But merely protecting the systems that hold data about citizens, corporations, and government agencies is not enough. The infrastructure of networks, routers, domain name servers and switches that glue these systems together must not fail, or computers will no longer be able to communicate accurately or reliably. Given the magnitude of secure cyberspace, a reflection on what are trying to do seems in order. Several questions arise, such as what exactly the infrastructure is, what threats it must be secured against, and how protection can be provided on a cost-effective basis. But underlying all these questions is how to de fine a secure system. What is security？ Having it is obviously good;everyone says so. But few people defines it exactly, or even nebu lously. This column tries to place cybersecurity in perspective, because it is, of course, central to countries, organizations, and even home users now and in the future
