校园网安全访问控制体系的构建

Construction of Security Access Control System for Campus Network

构建完善实用的校园网安全访问控制体系是防止黑客入侵以及网络病毒攻击,保证校园网安全、高效运行的前提和基础。该方案结合TCP/IP模型,从下向上依层次对校园网及其应用系统进行了分析研究,找出可能遇到的各种风险,通过制定身份验证、设置防火墙等有效的相应防御措施,打造出一个安全的校园网架构,有效防止与避免了由于各种原因导致的校园网数据丢失、被修改甚至系统瘫痪等事故的发生。近年来的实践证明,该方案设计合理,能有效满足校园网的安全需求。

The construction of perfect and practical campus-network security access control system is the premise and foundation to prevent the network hackers and virus attacks as well as guarantee the network safe and efficieht operation. The analitical investigation on the campus network and application access control system from below to top according to level is carried out to find out all kinds of risks that may he encountered in combination with TCP/IP model. A safe and efficient operation framework was built by making the corresponding effective defensive measures of identity authentication and setting the firewall. With it, the accidents caused by the loss or the modification of the campus networks data and the breakdown of the system were effectively prevented or avoided. The actual application in recent years proves that the scheme is reasonable and can effectively meet the safety requirement of campus networks.
