随着高校计算机网络的初具规模,各高校逐渐把主要精力转向网络应用和用户服务。然而高校计算机网络具有开放性、互联性和共享性的特点,因此不可避免地受到病毒、黑客、恶意软件和其他不轨行为的安全威胁和攻击,高校计算机网络数据丢失、系统被攻击修改、网络瘫痪的事情时有发生。因此,如何提高高校计算机网络安全性,使其适应网络技术和应用的新变化,就成为一个极具现实意义的问题。从宏观角度在通过引用历史文献资料对高校计算机网络的安全体系全面了解的基础上,通过比较分析,总结高校计算机网络安全中存在的问题并提出对策,从而为高校计算机网络的安全提供理论依据。
With the beginning of the computer network in colleges and universities, universities gradually shift their main focus to network applications and user services. However, university computer networks are characterized by openness, interconnectivity and sharing. Therefore, they are inevitably subject to security threats and attacks from viruses, hackers, malware and other misdeeds, data loss from computer networks in colleges and universities, system attacks being modified, and network downsets Things happen from time to time. Therefore, how to improve the security of computer network in colleges and universities so that it can adapt to the new changes of network technology and application becomes a very significant issue. On the basis of a comprehensive understanding of the security system of university computer network by referring historical documents from a macroscopic perspective, this paper summarizes the problems existing in the computer network security of colleges and universities and puts forward countermeasures by comparative analysis, so as to provide a theoretical basis for the security of computer network in colleges and universities.
