摘　　要：随着现代远程教育模式的深入开展,基于Web的远程教学系统面临着更大的安全风险.计算机病毒、非法访问、网络攻击等情况的频繁发生,使得提高系统的安全性成为远程教育工作中必须要考虑的一项重要内容.从远程教学网络体系构建和代理服务器功能等方面阐述了构造分布式网络远程教学系统的措施,并合理地应用了代理服务器.对系统的安全隐患进行深入分析,结合已有的工作经验,提出了多种技术结合的远程教学系统安全防范逻辑结构.With the development of modern distance education mode, the Web-based distance education system encounters more security risks. Improving system security is an important task for the current distance education, because computer viruses, unauthorized access and network attacks have occurred frequently. Aims at the security problem, this paper mainly deals with the solution for constructing distributed network-based distance education system from the following aspects. Distance education network architecture and proxy server＇ s function. And the proxy servers are applied in the system. The security risks are analyzed systematically in this paper. And based on related work, the security logical structure which includes multiple techniques on the distance system is presented.
