Abstract

The invention provides a protection method and device of a message. The method comprises the following steps: extracting a first feature value carried by a to-be-protected message when receiving to the to-be-protected message; computing based on the first feature value to obtain a first index value, and associating the to-be-protected message with one of the first rate threshold recorded in a preset rate matching table through the first index value, and determining the first rate threshold associated with the to-be-protected message as the second rate threshold, wherein the preset rate matching table is used for recording at least one first rate threshold; computing to obtain a first transmission rate of the to-be-protected message, wherein the first transmission rate is the total number of the received to-be-protected message with the same first index value in the first preset unit of time when the to-be-protected message is received; when the first transmission rate is less than thesecond rate threshold value, forwarding the to-be-protected message to the target equipment. Through the application of the protection method provided by the invention, a problem that the system resource consumption of the network protection equipment is large is solved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message protection method and device. Background technique [0002] Usually, when a network protection device protects a message to be protected, the network protection device performs feature matching on the message to be protected based on the characteristic value carried by the message to be protected, and then obtains the transmission rate of the message to be protected with different characteristic values ​​through feature matching. When the transmission rate is greater than or equal to the preset rate threshold, the network protection device performs protection processing on the packets to be protected. [0003] In the existing technical solutions, when the network protection device performs feature matching on the packets to be protected with normal transmission rate and no attack, the process of feature matching is unnecessary and takes up a lot of system ...
