Problems solved by technology

[0005] However, when defending against DDoS attacks in the prior art, it defends against a certain type of message that is determined to have an attack behavior. That is to say, if a certain type of attack is blocked, the gateway device will not process this type of normal message
Normal network activities will also be greatly affected, so this application provides a new method and device for message processing

Abstract

This application provides a method and device for message processing. For each received message, the actual message flow of the IP address can be determined according to the source Internet Protocol (IP) address of the message. According to Determine the flow direction information of the message, determine the security rule matching the flow information, thereby determine the flow threshold of the IP address, and determine whether the actual message flow of the IP address exceeds the flow threshold of the IP address, If yes, process the message according to the operation corresponding to the matched security rule; if not, forward the message according to the content of the message.

Description

technical field [0001] The present application relates to the technical field of network communication, and particularly designs a method and device for message processing. Background technique [0002] Distributed Denial of Service (DDoS) attack refers to that the attacker sends a large number of carefully constructed attack packets to the attacked target by controlling a large number of zombie hosts, causing the link congestion of the network where the attacker is located and system failure. Resource exhaustion makes it difficult for the attacker to provide services to normal users. figure 1 It is a schematic diagram of an existing DDoS attack. The terminal used by the attacker is on the left, and the server on the right is attacked by controlling the zombie host. Usually, DDoS attacks come from terminals on the intranet. [0003] Since DDoS attacks are usually based on the loopholes in the communication protocol between devices, DDoS attacks can usually be divided into ...
