Data network security protection method, device, computer equipment and storage medium

Abstract

The present application relates to a data network security protection method, device, computer equipment and storage medium. The method includes performing a control check on the data network and obtaining the result of the control check; the control check includes the control operation of the logged-in user account on the data network Check the program of the data network to obtain the result of the program check; the program check includes the check of the application program installed on the data network; check the data of the data network to obtain the result of the data check; the data check includes the data information entering and leaving the data network Check the connection of the data network to obtain the result of the connection check; the connection check includes the check of the internal and external connection relationship of the data network; according to the above inspection results, the security control of the data network is carried out. Realize the internal and external comprehensive protection of the railway signal safety data network, ensure the closure and independence of the railway signal safety data network, and enable the railway signal safety data network to have high-level security protection capabilities.

Description

technical field [0001] The present application relates to the technical field of network and information security, in particular to a data network security protection method, device, computer equipment and storage medium. Background technique [0002] The signal safety data network is a dedicated communication network for each control system of the railway signal system. The controlled subsystems, such as the train control center, computer interlocking, temporary speed limit server, and wireless automatic blocking system, are on-site control and execution systems for train operations. , to ensure the safe, orderly, stable and reliable operation of the train. After the signal security data network is invaded and destroyed, it will cause the train to run out of control, seriously threatening social order, public interest, people's personal and property safety. [0003] In the traditional technology, the signal safety data network and external systems are only isolated by fire...

Problems solved by technology

After the signal security data network is invaded and destroyed, it will cause the train to run out of control, seriously threatening social order, public interest, people's personal and property safety

[0003] In the traditional technology, the signal safety data network and external systems are only isolated by firewalls, and ordinary firewalls cannot effectively intercept intrusions to the signal safety data network, making the operation and maintenance security of the railway signal safety data network unable to be guaranteed
