1计算机网络安全的重要性与威胁分析计算机网络安全指的不仅是网络系统中数据的安全,而且其硬件以及软件的安全也包括在内,系统在运行的过程当中不会因影响因素而遭到破坏,发生数据更改以及信息泄露等。通常情况下,计算机安全主要包括两个部分,其中一个部分是信息安全,另外一个部分是物理安全,其中信息安全指的就是网络安全,主要用户确保网络的保密性、完整性以及可用性免遭威胁[2]。然而在科学技术快速发展的时代背景下,计算机网络安全的威胁不只 1 The Importance and Threat Analysis of Computer Network Security Computer network security refers not only to the security of data in the network system but also to the hardware and software security. The system will not be affected by influencing factors during operation Vandalism, data changes and information disclosure. In general, computer security mainly consists of two parts, one part of which is information security and the other part of which is physical security. Information security refers to network security. Main users ensure network confidentiality, integrity and availability from threats [2]. However, under the background of the rapid development of science and technology, the threat of computer network security is not only
