Abstract

The invention provides a processing method for network attacks and a device. The method comprises steps of by obtaining related information of received access requests in a to-be-monitored period, judging whether the network has been attacked in the to-be-monitored period; if the network has been attacked, obtaining times of the access requests corresponding to identifications of client ends and / or size of access data packages in the access requests in the to-be-monitored period; and obtaining client ends which are suspected to be attacked and abandoning the access requests sent by the client ends according to the times of the access requests corresponding to identifications of client ends and / or size of access data packages in the access requests in the to-be-monitored period. Thus, whether the network has been attacked can be determined by combining the received access requests of all client ends in the to-be-monitored period; the attacks can be precisely identified and defense can be performed; detection precision degree of DDOS attacks is improved; and detection efficiency and defense effects are improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a processing method and device for network attacks. Background technique [0002] Flooding distributed denial of service attack (Distributed Denial of Service, DDOS) is the most common attack method among the network attacks against the Internet Data Center (IDC) of operators, especially the DDOS attack against the application layer, such as HTTP flooding attack or hypertext Transmission protocol (HyperTextTransferProtocol, HTTP) host resource exhaustion attack. HTTP flooding attack refers to that the attack side sends a large number of requests to the attacked side, including normal requests, redirected pages, header information and other content to attack. The HTTP host resource exhaustion attack refers to that the attacking side sends a response packet requesting a large amount of data or a request requesting a high-complexity computing capability to the attack...
