近年来,随着科学技术的不断发展,我国的数据通信网络得到了广泛的普及,网络逐渐成为了人们日常联系、沟通的主要方式,为人们的生活带来了极大的便利。随着数据网络不断向数字化、智能化的方向发展,将会帮助人们更好的掌握丰富的信息。但数据网络传播的同时,也会出现一系列的安全问题,本文针对数据通信网络的安全问题进行了探讨,提出了合理化、科学化的解决措施,从而为络的安全性提供基础。 In recent years, with the continuous development of science and technology, the data communication network in our country has been widely popularized. The network has gradually become the main way of people’s daily contact and communication, bringing great convenience to people’s life. As the data network continues to be digitized and intelligent, it will help people better grasp the rich information. However, there are also a series of security problems that occur when the data network spreads. In this paper, the security problems of the data communication network are discussed, and reasonable and scientific solutions are put forward to provide the basis for network security.
