Abstract: The present application provides data processing methods and apparatuses. A data processing apparatus can include: a communication interface; a memory storing a set of instructions; and at least one processor configured to execute the set of instructions to cause the apparatus to perform: receiving a target data packet sent by a network device; cleaning the target data packet; and sending the cleaned target data packet to a target website server.

Abstract: A method including parsing an attack packet when a network attack is detected, wherein the attack packet includes address information; locating a first gateway device according to the address information; and sending a first instruction to the first gateway device, wherein the first instruction is used for instructing the first gateway device to perform security control on a terminal to which the attack packet belongs. The present disclosure solves the technical problem of low defense efficiency when a target server under attack defends passively due to the lack of techniques of monitoring and countering network attacks in conventional techniques.
