如何提高计算机网络的安全性

在危及网络安全运行的诸多因素中，单点故障在高可靠性的网络中显得尤为突出，随着计算机网络规模的增大，对安全性的要求也日趋提高。不仅要求在某几个关键的方面建立安全保障，而且需要一个全面的、系统的解决方案。文章主要介绍了利用冗余技术防止网络单点故障的实现方案，对几个影响系统安全、而又经常被忽视的薄弱环节诸如电源、网卡等详细地进行了讨论，以利于那些已经运行的计算机网络或正在规划中的网络能更安全、更经济地运行。

COMPUTER APPLICATION How to enhance safety of the computer network

Among the factors endangering computer network safety the single point fault is an important one.And with increasing scale of the computer network the requirement to safety is corresponding stricter,then a complete solution to be provided for computer network.the paper gives an introduction to a scheme to prevent computer network from single point fault by using redundancy technology and analyses some factors such as power supply,adapter and etc,which are often ignored in practice.
