进入21世纪以来,我国进入了信息时代。信息时代给人们的生活带来了方便,但同时也出现了一些问题,首要问题就是网络安全。安全出现问题,不仅会泄露用户个人信息,威胁到个人生命财产安全,还有可能会泄露国家机密,对国家发展造成难以挽回的影响。近年来,因为信息泄露造成的危害事件屡禁不鲜,严重影响了人们的生活,也让大家心惊胆战,越来越没有安全感,信任度大大降低。而计算机又是人们生活中不可缺少的一部分,是人们依赖的工具之一,这样就会产生一定的矛盾。因此,必须要加强计算机网络安全,提高防御技术,改变现状。本文主要研究的就是计算机网络安全现状,以及提升防御技术的手段,保障使用安全。
Since entering the 21st century, our country has entered an information age. The information age has brought convenience to people’s life, but at the same time, some problems have appeared. The primary issue is network security. Security problems will not only reveal personal information of users, threaten the safety of personal lives and property, but may also reveal state secrets and cause irreparable impact on the development of the country. In recent years, because of information leaks, the harmful events that have been caused by repeated leaks have seriously affected people’s lives. They have also made everyone feel frightened and insecure and their trust has been greatly reduced. The computer is an indispensable part of people’s lives, one of the tools people depend on, which will produce some contradictions. Therefore, we must strengthen computer network security, improve defense technology and change the status quo. The main research of this paper is the current status of computer network security, as well as ways to enhance defense technology to ensure the safe use.
