A case of reliable remote functionality
Ganghua Lin · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2008
All data are provided by Huairou Solar Observing Station (HSOS), Beijing, China, a main observation station that is designed to predicate solar activities and space environment in China. With the more and more complicated Internet environment, many security issues arise, such as viruses, attacks to potential security weakness in the network protocol, improperly using operation systems within a network etc., we have to design a more secure and reliable network architecture in order to implement remote functionalities to meet the demands of the data users: automatic data transmission, remote observation, control and maintenance of various systems. In this article, the author presents a real case discussing various aspects while implementing it, that includes a new network topology changed from an original architecture to a more secure one, the selections of the secure products, secure strategies deployment, the problems encountered during operation and the solutions in use at HSOS. The article also gives some inputs from the author's experiences of the network security. The case is implemented in the entire observing station, which includes multiple observing systems, at HSOS.
