Abstract

The invention provides a communication interception method and device, and a server. The method comprises the steps of: determining whether a data message of the network flow is a data message sent to a pre-set main control server or not; when the data message of the network flow is the data message sent to the pre-set main control server, determining the source IP address of the data message, and constructing a response message corresponding to the data message; and sending the response message to a cloud server, the IP address of which in a cloud computer room is the source IP address. By means of the technical scheme in the invention, communication between a puppet machine and the pre-set main control server can be rapidly blocked; and thus, attack from the puppet machine to the server can be avoided at source.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a communication interception method and device, and a server. Background technique [0002] When the server in the cloud is invaded into a puppet machine, the attacker sends instructions to the puppet machine through the master control server (Command&Control Server, referred to as C&C server), and the puppet machine initiates a large number of requests to the attacked server to perform distributed denial of service ( Distributed Denial of Service, referred to as DDoS) attack. When an attacker uses a botnet of a certain scale to carry out a DDoS attack, the attacked server can be paralyzed. Contents of the invention [0003] In view of this, the present application provides a new technical solution, which can effectively intercept the communication from the puppet machine to the main control server. [0004] In order to achieve the above object, the application pro...
