Problems solved by technology

However, the ACL resources of the BRAS equipment are limited. When the attacking user scale is huge and the ACL resources of the BRAS equipment are exhausted, the attack packets are sent to the CPU (Central Processing Unit, central processing unit) for processing, causing an impact on the CPU.

Abstract

The invention provides an attack prevention processing method and device. The attack prevention processing method comprises the steps of locally sending ACL (Access Control List) by a superior device based on an obtained MAC (Media Access Control) address of an attacking terminal; when the number of the ACL used by the superior device per se reaches a preset ACL threshold value and a subordinate device exists at the interface where an attack message is received, sending the MAC address of the attacking terminal to the subordinate device; and after the subordinate device receives the MAC address of the attacking terminal, sending the ACL at the interface where the MAC address of the attacking terminal is learned, and filtering the attack message sent by the attacking terminal. The attack prevention processing method and device can enhance the attack prevention capability of the network and can reduce resource consumption of a BRAS (Broadband Remote Access) device.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to an attack prevention processing method and device. Background technique [0002] PPPoE (Point-to-Point Protocol over Ethernet, point-to-point protocol based on Ethernet) is a technology for rebroadcasting PPP (Point-to-Point Protocol, point-to-point protocol) frames in Ethernet. With the increasingly widespread application of PPPoE, attacks against PPPoE networks are also becoming more frequent. [0003] At present, the anti-attack technology mainly utilizes BRAS (Broadband Remote Access Server, Broadband Remote Access Server) equipment in the PPPoE network for defense. The BRAS device is responsible for attack message detection, and sends the attack user information of the attack message to the hardware ACL (Access Control List, access control list), and filters the attack message through ACL matching. However, the ACL resources of the BRAS equipment are ...
