Information security in intelligent mass transit management systems

Aim. The paper examines matters related to the definition of the architecture and requirements for data communication networks as part of intelligent mass transit management systems. Methods. The paper suggests a network architecture using multiprotocol label switching (MPLS) technology and traffic routing. If the core of a local area network is implemented using fully-connected topology, the use of flow labels allows predefining information exchange routes between servers and applications of an information and telecommunications network (ITS). Multiprotocol label switching (MPLS) is the foundation of control and information acquisition networks of ITS. That allows adopting common interfaces to the subsystems that perform various functions within an ITS, e.g., control and diagnostics, minimizing the time of information delivery to management servers and sending critical control commands, as well as using common Ethernet or 4G/5G wireless interfaces. Conclusions. The path installation/removal principle, when applied to critical facilities, significantly complicates attacks and collection of information on the network structure of ITS.
