随着我国计算机网络技术的飞速发展,计算机网络安全已经成为社会稳定发展的重要保障,信息安全的涵义也因此发生了很大的变化。它不但从一种一般防卫转变成了一种十分普通的防范工作,并且还从一个特殊的领域变成了无处不在。各方面的许多机密信息,甚至国家机密难免会引来各种人为攻击。本文首先介绍了计算机网络安全的含义和特征,继而分析了目前计算机网络安全所面临的威胁,最后本文提出了维护计算机网络安全的措施。
With the rapid development of computer network technology in our country, computer network security has become an important guarantee for the stable development of society. The meaning of information security has also undergone great changes. Not only has it transformed itself from a general defense into a very common precaution, it has also evolved from a particular area to being ubiquitous. Many kinds of confidential information in all aspects and even state secrets inevitably lead to various man-made attacks. This paper first introduces the meaning and characteristics of computer network security, then analyzes the current threats to computer network security, and finally proposes measures to maintain computer network security.
