A new idea on network security protection of urban rail transit signal system in the era of classified protection 2.0

Abstract： With the indepth implementation of the network security law,hierarchical protection system has become the basic system of national network security in the new era.With the classified protection 2.0,network security protection objects have realized the full coverage of cloud computing, big data, Internet of Things, mobile Internet, industrial control system.Combined with the requirements of the new standard of classified protection 2.0 and the construction requirements of network security of urban rail transit signal system,this paper puts forward a new idea of network security protection of urban rail transit signal system according to the core idea of "one center,triple defence".

Key words : urban rail transit；signal system；network safety；classified protection 2.0
