校园网改造设计及网络安全设计分析

The Analysis of the Design of Rebuilding Campus Network and Network Security

伴随着网络应用的日益普及和深入,中职学校对网络信息技术要求越加提高。现有的校园网网络模型已经不能满足学校日益增长的数字化要求,并且内部网络中的主机也会受到非法入侵者的攻击,网络中的敏感数据有可能泄露或者被篡改。保证校园网络系统的保密性、完整性、可用性、可控性、可审查性,都是现代化校园网络比不可少的基本要求。通过对原有网络的拓扑结构、组网技术及网络设备的升级等方面的设计,对网络功能的拓展及网络安全进行完善显得尤为重要。

Along with the increasing popularity of the network application, and the tendency that the network server is apt to be invaded illegally and the data is prone to be revealed or changed, the current campus network is unable to meet the need of the vocational schools,which implies that better network information technologies are demanded. Therefore, it is an essential and basic requirement for the modern campus network to be confidential, complete, useable, controllable and investigable and obviously, it is significant to improve the function and network security by upgrading the original topological structure, networking technology and network equipment.
