摘　　要：随着计算机网络的不断发展,信息安全问题日益成为企事业单位关注的焦点。目前,由于网络环境复杂,各单位内外网信息交换的需求逐渐增加。针对气象系统双网隔离的建设需求,简述了网闸和隔离区(Demilitarized Zone,DMZ)技术的应用原理。同时,结合气象部门实际业务,设计基于网闸和DMZ的双防火墙安全隔离系统,保证了气象信息跨网交换的安全性。With the continuous development of computer networks,information security issues have become increasingly the focus of attention from enterprises and institutions.The current network environment is complicated,and the demand for information exchange of internal and external networks in each unit has gradually increased.For the construction needs of dual-network isolation for meteorological systems,the author briefly described the application principle of gatekeeper and Demilitarized Zone(DMZ) technology.Combined with the actual business of the meteorological departments,we design a double firewall safety isolation system based on gatekeeper and DMZ.The system Improves the safety performance of meteorological information cross-network exchange.
