The internet and online service hall access platforms are logically isolated from the Internet and meet the relevant functional requirements of level 3 protection. The comprehensive audit system guarantees WEB logs, database logs, server logs, etc.. Two unidirectional import and export channels are established using two security isolation and one-way transmission systems (ie, one-way optical shutters) to exchange data between internal and external networks, and to perform protocol stripping, format checking and content filtering on incoming and outgoing data.
Implementation Effect:
This solution uses the LREC9801BF-TX/RX Gigabit SFP module + one-way transmission module used by customers of a technology company, which has great influence in the network gate industry to enable direct transmission of data. At present, it is very useful to transfer data between many administrative units and extranets. Because of the dense network of the government's internal network and the external network (connected to the Internet) is "physically isolated", but many government affairs documents on the external network are expected to be used in the internal network, and the workload is high due to manual copying.
