Problems solved by technology

Although it is possible to ensure that one firewall is in working condition, it is easy to cause network congestion when the industrial control data traffic is large. In addition, due to the complex network topology, some scenarios are not suitable for dual-machine or multi-machine mode.

Abstract

The invention discloses an industrial control data processing method, the method is applied to firewall equipment, the firewall equipment comprises a main agent and a standby agent, the method comprises the following steps: carrying out security detection on received to-be-detected industrial control data through the main agent, and detecting the load of the to-be-detected industrial control data through the standby agent; and under the condition that the load of the to-be-detected industrial control data meets a first condition, performing security detection on the to-be-detected industrial control data through the main agent and the standby agent together. The firewall equipment applying the method can meet the firewall arrangement requirement of a scene which is not suitable for a dual-computer or multi-computer mode, and a main/standby mode can be formed through one firewall equipment, so that the firewall equipment has relatively high robustness. Moreover, the main agent and the standby agent can perform security detection on the industrial control data together, so that the large-load industrial control data detection requirement can be met, and network congestion is not easy to send.

Description

technical field [0001] The present application relates to the technical field of firewalls, in particular to a data processing method and firewall equipment. Background technique [0002] With the advent of the industrial information age, the safety and reliability requirements of the industrial field are getting more and more attention. Industrial safety equipment must not only meet business needs, but also ensure the goal of zero-fault industrial production. Therefore, the reliability and practicability of industrial firewalls have attracted the attention of industrial manufacturers. [0003] The reliability of existing industrial firewalls is mostly based on the high-availability dual-system hot backup solution, which requires the deployment of two industrial firewalls with the same functions and functions at the industrial production site. When one firewall detects industrial control data, the other One firewall is in the backup state, and only when the one firewall fa...
