Abstract

The embodiment of the invention discloses a message matching method comprising the following steps: receiving message, determining access control list (ACL) rules which match with message attribute information, and acquiring a message processing strategies which correspond to the ACL rules, wherein the message processing strategies which correspond to the ACL rules comprises the matching of the transmission layer or application layer of the message; and matching the transmission layer rules of the transmission layer data of the message or the application layer rules of the application layer data of the message according to the message processing strategies which correspond to the ACL rules. The embodiment of the invention further discloses a message matching device. The message matching method and the message matching device can be used for deeply identifying the message.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message matching method and device. Background technique [0002] Before the current network security detection device distributes the received message to other devices, it usually needs to match the received message with a preset rule to decide whether to forward the message. Specifically, when the message is currently matched, when the message is a TCP (Transmission Control Protocol, Transmission Control Protocol) message or a UDP (User Datagram Protocol, User Datagram Protocol) message, the quintuple of the message is extracted Information, the five-tuple information includes: source IP (Internet Protocol, interconnection protocol between networks) address, destination IP address, protocol number, source port number and destination port number; and combine the five-tuple information with ACL (Access Control List, access control list) rules, if the ACL rule is not mat...
