近年来,互联网的快速发展使得计算机网络技术在社会各领域实现了高效的应用,为人们的生产与生活带来了诸多便利。然而,计算机网络在为社会经济带来巨大效益的同时,也伴随着越来越多网络信息安全问题。这些网络安全隐患主要是来自网络系统硬件或软件、系统数据遭受破坏、更改与泄漏,导致网络服务中断,系统运行受阻。为抵御计算机网络信息安全风险,必须对计算机软硬件及网络信息数据实施安全防护,确保计算网络信息系统安全运行。
In recent years, the rapid development of the Internet has enabled computer network technology to be efficiently applied in all fields of society, bringing many conveniences to people’s production and life. However, the computer network has brought enormous benefits to the society and economy as well as more and more network information security problems. These network security risks mainly come from the hardware or software of the network system, and the system data is damaged, altered and leaked, which leads to the interruption of the network service and the system operation is blocked. In order to resist the information security risks of computer networks, the computer software and hardware as well as the network information data must be protected to ensure the safe operation of the computing network information system.
