Abstract

The invention provides an anti-attack method, device and equipment, and a machine readable storage medium. The method comprises the steps of receiving a release message; monitoring the IPOE user tableentry as a corresponding IPOE user table entry according to the information carried by the release message; and if the service message corresponding to the IPOE user table entry is received within the preset time, discarding the release message. Through the technical scheme, after a release message is received, a hit IPOE user table entry is monitored, and if the normal service message corresponding to the IPOE user table entry can still be received within a certain time, the received release message is considered to be an attack behavior, and the release message is discarded and offline processing is not performed on the corresponding IPOE user, so that the possibility of abnormal offline of the normal user caused by the attack of the release message is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to an attack defense method, device, equipment, and machine-readable storage medium. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol, which refers to a segment of lP (Internet Protocol, Internet Protocol) address range controlled by the server. When the client logs in to the server, it can automatically obtain the server allocation. lP address and subnet mask. [0003] BRAS (Broadband Remote Access Server, Broadband Access Server) is a new type of access gateway for broadband network applications. It is located at the edge layer of the backbone network and can complete IP / ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode) network data transfer of user bandwidth. Access to achieve broadband Internet access for terminals, IP VPN (Virtual Private Network, virtual priv...
