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

Abstract

The invention relates to a data network security protection method and a device, computer equipment and a storage medium, and the method comprises the steps: carrying out the control check of a data network, and obtaining a control check result; wherein the control check comprises check of a control operation performed on the data network by the logged-in user account; performing program inspection on the data network to obtain a program inspection result; wherein the program inspection comprises inspection of an application program installed in the data network; performing data check on the data network to obtain a data check result; wherein the data inspection comprises inspection of data information entering and exiting the data network; performing connection check on the data network to obtain a connection check result; wherein the connection check comprises check of an internal and external connection relationship of the data network; and performing security management and controlon the data network according to the check result. Internal and external comprehensive protection of the railway signal safety data network is realized, the closure and independence of the railway signal safety data network are ensured, and the railway signal safety data network has high-grade safety protection capability.

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
