Abstract

The invention discloses a message processing method, a firewall and a readable storage medium, and the message processing method comprises the steps: receiving a request message sent by a terminal, and when determining that the request message has illegal content, modifying the illegal content to obtain a target message, the content of the target message being legal content; sending the target message to a controller, so that the controller sends a response message after receiving the target message; and receiving the response message, determining that the response message does not have illegal content, and sending the response message to the terminal. The problem that when a firewall determines that illegal content exists in a message, connection between a terminal and a controller will be disconnected is solved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a message processing method, a firewall and a readable storage medium. Background technique [0002] In the current industrial system, in order to ensure the security of the communication between the terminal and the controller, a firewall is usually used to protect the communication between the terminal and the controller. After the firewall detects that the message sent by the terminal to the controller contains illegal content, the firewall usually adopts two methods to protect the communication security. One is to discard the message. Using this method will trigger the retransmission mechanism of the TCP transmission control protocol. , after repeated retransmission failures, the connection is interrupted; the other is to send a reset message to close the current connection. Using both protection methods will interrupt the connection between the terminal ...
