Industrial control network security early warning method and system

The invention discloses an industrial control network security early warning method and system, and relates to the technical field of network security, and the method comprises the steps: carrying out the vulnerability penetration test of a network terminal of each user; performing data processing to obtain a safety reference parameter of the network terminal of each user; generating user group tags, and performing simulation attack on all users in each user group tag; according to the attack simulation parameter of each user group label, performing integration processing to obtain a user emergency response parameter of each user group label; performing early warning on a network security administrator, generating a simulation attack period corresponding to each user group label, and sending the simulation attack period to the network security administrator; according to the invention, the simulation attack period of each user group tag is generated according to the user emergency response parameter of each u
