保证安全的最大困难在于了解系统的弱点。假如你是一个PC Week的忠实读者,就会对安全性有相当丰富的知识。但你是否曾试图攻击过你自己的系统呢?大多数人都没有足够多的机器和连接来完成对自己系统的安全性测试。或许是因为害怕被ISP探测到并中断此类测试,我们中的一部分人羞于进行端口扫描和服务器测试,甚至不愿对自己的系统进行类似的操作。 The biggest difficulty in ensuring safety is knowing the weaknesses of the system. If you are a loyal PC Week reader, you have a wealth of knowledge about security. But have you ever tried to attack your own system? Most people do not have enough machines and connections to complete their system security testing. Perhaps because of the fear of being detected by the ISP and disrupting such tests, some of us are ashamed of port scans and server tests, and do not even want to do something like this on our own systems.
