随着计算机网络技术的快速发展,信息化进程的深入,计算机安全问题越来越引起人们的广泛关注。究其原因主要是许多重要的信息存储在网络服务器或计算机上,一旦这些信息泄露将对信息所有者造成无法估量的损失。之所以信息会泄露,一方面有许多不法分子或黑客千方百计想得到一些他人的重要数据;另一方面网络自身存在安全隐患才使得入侵者有机可乘。网络安全既有技术方面的问题,也有管理方面的问题,两方面相互补充,缺一不可。针对这些问题,本文首先对计算机网络安全的概念进行了简要概述,然后分析了影响计算机网络安全的因素,最后提出了一些计算机安全防护技术和方法,以供参考。
With the rapid development of computer network technology and the deepening of information technology, computer security has drawn more and more attention. The main reason is that many important information is stored on the network server or computer, once the information is leaked, it will incur immeasurable loss to the information owner. The reason why the information will be disclosed, on the one hand, many criminals or hackers do everything possible to want to get some important data of others; the other hand, the network itself has security risks make the invaders take advantage of. There are both technical and cyber security issues in cybersecurity, which are mutually reinforcing and indispensable. In response to these problems, this paper first briefly summarizes the concept of computer network security, and then analyzes the factors that affect the security of computer networks. Finally, some computer security protection techniques and methods are proposed for reference.
