为了解决日益严重的局域网的安全问题,提出一种安全的基于网络的计算机系统模型。该模型以透明计算机系统为基础,利用透明计算技术对计算机内部的安全问题进行控制。针对网络内主机间的安全问题,采用星型拓扑结构,在网络的中心位置引入监控器设备,监控系统中各个部件之间的通信过程,以实现对主机与服务器之间、主机之间及主机与外网之间的通信数据过滤和动态物理隔离,提高了系统的安全性。理论分析表明:该系统可有效地解决网络安全问题,从而为局域网提供了可靠的安全保证。
In order to solve the increasingly serious problem of local area network security, a secure network-based computer system model is proposed. Based on the transparent computer system, the model uses the transparent computing technology to control the internal security of the computer. For the network between the host security issues, the use of star topology, the introduction of monitoring equipment in the center of the network to monitor the communication between the various components of the system in order to achieve the host and server, between the host and the host And the communication between the external network data filtering and dynamic physical isolation, improve system security. The theoretical analysis shows that the system can effectively solve the network security problem, thus providing a reliable guarantee for the local area network.
