基于CDN技术的高校网络安全建设探索

Exploration of Network Security Construction in Colleges and Universities Based on CDN Technology

开放大学学生数量较多,且大部分通过线上学习。为了保障高校网络安全,通过CDN结合WAF防护Web服务器。其中,通过CDN过滤DDoS攻击,WAF阻挡恶意Web攻击,两者结合能够有效阻断传统防火墙无法隔离的网络攻击。同时,在学校安全管理体系建设中提出网络安全闭环管理,从网络安全制度建立、人才队伍建设、安全运维服务、应急响应预案、安全培训、“等保2.0”等方面完善网络安全管理体系。实践表明,通过对学习平台部署CDN服务,学员学习体验较好,信息传输更安全、可靠。该方法能够为高校网络安全建设提供参考与借鉴。

Due to the large number of students in the Open University,most of them are online learners.In order to ensure the network securi⁃ty of universities,web servers are protected through CDN combined with WAF.The combination of CDN filtering DDoS attacks and WAF blocking malicious Web attacks can effectively block network attacks that cannot be isolated by traditional firewalls.At the same time,in the construction of the school's security management system,a closed-loop management of network security is proposed,which improves the net⁃work security management system from aspects such as establishing a network security system,building a talent team,providing security oper⁃ation and maintenance services,emergency response plans,security training,and"equal protection 2.0".Practice has shown that by deploy⁃ing CDN services on the learning platform,students have a better learning experience and information transmission is more secure and reli⁃able.This method can provide reference and inspiration for the construction of network security in universities.
