摘要
物理隔离目的是为防止信息泄漏和外来闯入来保证内部网络的安全性。而数据转发却是要与外网进行通信。对于这两个方面存在的矛盾性,提出一种基于物理隔离的数据安全转发的技术方案。这种方案使内外网在传输数据、辐射和存储介质上达到物理隔离,利用定向采集、中间缓冲、数据扫描等技术,使内外网络在不连通的情况下实现动态、准实时的数据安全转发。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安全分析,探讨了安全策略,提出了安全措施。
The aim of Physical Isolation is to prevent computers from being attacked from the outside and giving the information away. Data transmitting is corresponded with the outside world. Regarding the contradiction between Physical Isolation and Data transmitting. This paper puts forward a kind of technological conception about data transmitting safely based on the physics isolation. The＇ conception is to maintain the internal and external network in conductivity and radiation and physics cut off so as to transmit data in the condition of the internal and external network in disconnection , using directional collection , intermediate buffer and data scanning. In this 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 , This paper also discussed the safe strategy and made some safe measures.
