Abstract

The embodiments of this specification provide a method, device and network device for acquiring an access control rule. In the embodiment of this specification, when an industrial protocol message is received, the target industrial protocol corresponding to the industrial protocol message is identified, and the target self-learning parameter corresponding to the target industrial protocol is obtained according to the preset correspondence between the industrial protocol and the self-learning parameter , based on the target self-learning parameters, the rules of the industrial protocol messages are self-learning, and the access control rules corresponding to the target industrial protocols are obtained, and the access control rules corresponding to the industrial protocols can be automatically and intelligently obtained without manual configuration, thus avoiding artificial Misconfiguration of access control rules caused by various factors improves the accuracy of access control rule configuration.

Description

technical field [0001] This specification relates to the technical field of network communication, and in particular to a method, device and network equipment for acquiring access control rules. Background technique [0002] An industrial protocol is a communication protocol used in industrial systems. The industrial protocol itself has no encryption, authentication and other measures. Therefore, the industrial protocol message is transmitted in plain text, which has a large security risk. [0003] In order to reduce this potential safety hazard, an industrial firewall is set between the industrial client and the industrial server in the related art. On the industrial firewall, manually configure the access control rules of an industrial protocol, and use the access control rules to filter and forward the packets of this industrial protocol. In this method, the access control rules need to be manually configured, the workload is heavy, and the process is cumbersome, so it ...
