伴随着Internet的日益普及,网络应用的蓬勃发展,网络信息资源的安全备受关注。校园网网络中的主机可能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被修改,保证网络系统的保密性、完整性、可用性、可控性、可审查性方面具有其重要意义。通过网络拓扑结构和网组技术对校园网网络进行搭建,通过物理、数据等方面的设计对网络安全进行完善是解决上述问题的有效措施。 With the increasing popularity of the Internet, the rapid development of network applications, the safety of network information resources has drawn much attention. Hosts in a campus network may be attacked by illegal intruders, and sensitive data in the network may be leaked or modified to ensure the confidentiality, integrity, availability, controllability and audibilty of the network system. significance. It is an effective measure to solve the above problems by constructing the campus network through the network topology and network technology, and perfecting the network security through the design of physics and data.
