Abstract

The embodiment of the present application provides a message processing method and device. The method includes: sending a verification request to the source device when it is detected that the first number of packets sent from the source device received within a preset time period is greater than a preset number threshold, and the verification request is used to indicate that the source device Feedback verification information used to verify whether the above packet is an attack packet; receive the verification information sent by the source device for the above verification request; if the verification information is legal, when the above packet is determined to be an attack packet according to the verification information, Discard the above packets. Applying the solutions provided by the embodiments of the present application can improve network security.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message processing method and device. Background technique [0002] With the rapid development of Internet technology, the forms of network attacks are constantly updated, which has brought great troubles to Internet users. In a common network attack, an attacker can forge an Internet Protocol (IP) address, generate a sufficient number of attack packets, and launch an attack on one or more devices in the network, causing the attacked device to fail to provide Normal service, network security is not high enough. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a message processing method and device, so as to improve network security. [0004] In order to achieve the above purpose, the embodiment of the present application discloses a message processing method, which is applied to a network device,...
