Abstract

The invention discloses a network attack detection method, device, system, electronic equipment and storage medium. The method includes: receiving a heartbeat message transmitted in a local area network based on a multicast protocol; Extract the device data corresponding to the device ID from the message; estimate the current time of the second device according to the device data corresponding to the device ID, obtain the estimated time stamp of the second device, and request the second device according to the estimated time stamp of the second device The device returns a response message; when receiving the response message returned by the second device, check the identity validity of the second device according to the estimated time stamp of the first device in the response message; if the second device fails the identity verification , it is confirmed that the first device is under a network attack. The invention solves the problem of poor security of network-based data transmission in the prior art.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a network attack detection method, device, system, electronic equipment and storage medium. Background technique [0002] With the development of Internet technology, data transmission is more and more inclined to rely on the Internet, followed by network-based data transmission is vulnerable to network attacks, resulting in poor security. [0003] Currently, types of network attacks include: UDP (User Datagram Protocol, User Datagram Protocol) reflection attack, TCP (Transmission Control Protocol) reflection attack, replay attack, and the like. [0004] Among them, the replay attack means that the attacker intercepts the data packet received by the attack target (such as a server), does not make any modification, and then sends it to the attack target intact, so as to realize certain functions, so that the attack target is attacked by the network. attack. [0005] It...
