A device security protection method, apparatus, device and medium for deterministic network

Abstract

The present invention discloses a device security protection method, apparatus, device and medium for a deterministic network, which effectively solves the problem of limitations existing in traditional security protection systems in deterministic networks. The method includes: pre-constructing a security service component library for the deterministic network based on the application scenarios of the deterministic network; the security service component library includes a firewall module, an intrusion detection module, a traffic analysis module and a security perception module; controlling the firewall module, the intrusion detection module and the traffic analysis module to respectively monitor the operation of multiple devices in the deterministic network in real time to obtain event data, and inputting the event data to the security perception module; analyzing the event features in the event data, enabling the security perception module to obtain new-type security events, generating corresponding security rules based on a preset rule base with an automatic update mechanism, and executing the security rules to realize device security protection for the deterministic network.
