随着信息化进程的深入和网络的迅速发展,人们的工作、学习和生活方式正在发生巨大变化,效率大为提高,信息资源得到最大程度的共享。但必须看到,紧随信息化发展而来的网络安全问题日渐凸出,由于计算机网络的特性,产生了许多安全问题:信息泄漏、信息污染、信息不易受控等。本文就此提出了简单的解决方案。 With the deepening of the informationization process and the rapid development of the Internet, people’s work, study and lifestyles are undergoing tremendous changes, resulting in greatly improved efficiency and maximum sharing of information resources. However, it must be noticed that the network security problems that come immediately after the development of informatization have become increasingly prominent. Due to the characteristics of computer networks, many security problems have arisen: information leakage, information pollution, and information not easily controlled. This paper presents a simple solution.
