按照现在通行的观点,网络安全涉及到三个方面的内容:首先是网络硬件,第二是网络操作系统,即对于网络硬件的操作与控制;第三就是网络中的应用系统。若要实现网络的整体安全,考虑上述三方面的安全问题也就足够了。但事实上,这种分析是不完整和不全面的,因为无论是网络本身还是操作系统与应用程序,它们最终都是要由人来操作和使用的,所以还有一个重要的安全问题就是用户的安全性。
According to the prevailing viewpoints, network security involves three aspects: the first is the network hardware, the second is the network operating system, that is, the operation and control of the network hardware; the third is the application system in the network. In order to achieve the overall network security, consider the above three aspects of security issues will be sufficient. But in fact, this analysis is incomplete and incomplete, because both the network itself and the operating system and applications, they are ultimately to be operated and used by people, so there is another important security issue is the user Security.
