1. An information security protection method, comprising:
allocating a train control and monitoring system to an intranet region;
performing region boundary security protection on the train control and monitoring system;
performing communication network security protection on the train control and monitoring system; and
performing terminal device security protection on the train control and monitoring system,
wherein the performing of the communication network security protection comprises:
deploying a distributed safety monitoring device in an intranet sub-area to carry out distributed security analysis, wherein
the intranet sub-area is an independent marshalling vehicle level network of the train, and
the intranet region is a train level network of the train, including multiple intranet sub-areas, and
the distributed safety monitoring device is configured to send alarm information to a centralized safety monitoring device in response to a detected abnormality; and
deploying the centralized safety monitoring device in the train level network to analyze application service security of the train control and monitoring system,
wherein the centralized safety monitoring device is configured to execute a unified safety alarm according to abnormal information detected by the centralized safety monitoring device and the alarm information sent by the distributed safety monitoring device.
