基于GAP技术的气象网络物理隔离方案的探讨

Discussion on the GAP-based Meteorological network Isolation Plan

气象网络大多采用双布线的方式实现物理隔离,随着管理网络安全的复杂性等因素影响,不适应性逐渐突出。为了解决这些矛盾,该文基于安全隔离网闸(GAP)技术对原有网络的隔离方案进行改造。在实现内外网物理隔离的前提下,满足网间的实时、可控的数据交换和应用服务,从技术措施上保障了网络的安全,适应气象业务的新发展。

Most meteorological networks adopt the bi-wiring method to achieve physical isolation. Under the influences from factors such as the complexity of the security of managing network, the bi-wiring method has become increasingly problematic. In order to solve these problems, this paper sets about reforming the original network isolation plan with the GAP technology. To safeguarding the network safety and adapting the new development of meteorological service, it provides a method on real-time, controllable data exchange and application services based on the physical isolation of the internal and external network.
