计算机网络安全与防御措施研究

由于计算机网络技术的迅速发展，病毒、网络攻击等现象的出现，使计算机网络安全问题面临着严峻的考验．本文通过明确计算机网络安全的定义，深入分析和探讨计算机网络存在的各类安全隐患，在此基础上提出相应的计算机网络防御措施，为我国计算机网络安全技术的完善和发展奠定了基础。

Study on computer network security and defense measures

As a result of the rapid development of computer network technology, the computer network security Issues taced a severe situation, because of viruses, network attacks and so on. Through defining the computer network security clearly, various types of computer network security risks were analyzed and discussed deeply. Based on that, appropriate computer network defense measures were proposed. The study laid the foundation for the improvement and development of computer network security technology.
