物理隔离技术分析及其数据安全转发模型

本文在物理隔离方案的技术分析的基础上，提出了一种基于物理隔离的数据安全转发模型，详细地讨论了物理隔离条件下数据转发的技术途径和实现方法，并针对可能出现的安全隐患进行了分析，探讨了安全策略，提出了安全措施，保证在数据通信的基础上，从物理上把企业内部网与因特网相互隔离，以提高原有系统的安全性。

Technology Analysis and Transmission Model of Data Safety Based on Physical Isolation

Information security is important of network application. Physical Isolation obdurate is to prevent computers from being attacked from the outside and giving the information away. Data transmitting openness is linked up with the outside world. Based on analyzing physical isolation scheme, the paper puts forward a kind of technological model about data transmitting safety based on the physical isolation. In the paper, the technological channels and the methods of data transmitting have been discussed in detail in the condition of physical isolation. According to the hidden trouble, the paper also discussed the safe strategy and made some safe measures. The system physically separates the Internet and Intranet based on data exchange. So the security of Intranet is greatly enhanced.
