Abstract

The invention relates to a network intrusion detection method, a device, a system and a storage medium. The network intrusion detection method comprises the steps of: analyzing protocol data units ofa request packet and a response packet to obtain parameters of the protocol data units, wherein the response packet is a data packet responding to the request packet in the same session; judging whether the parameters of the protocol data unit accord with a first preset rule or not; and when judging that the parameters of the protocol data unit do not accord with the first preset rule, transmitting a first alarm message used for indicating that network intrusion exists. Through adopting the network intrusion detection method, the problem that intrusion detection of a session level cannot be supported in related technologies is solved, and the beneficial effect of intrusion detection of the session level is realized.

Description

technical field [0001] The present application relates to the field of network security, in particular to a network intrusion detection method, a network intrusion detection device, a network intrusion detection system and a computer-readable storage medium. Background technique [0002] ICS (Industrial Control System, industrial control system), referred to as industrial control system. The industrial control system is different from the traditional Internet environment. The industrial control system usually has a specific production goal. To achieve this goal, a clear production logic has been formulated and strictly followed in actual operation. Therefore, once a certain industrial control equipment is used, its Communication patterns, communication traffic, communication objects and other related information are usually stable. Once an intruder breaks into the industrial control system, it is easy for the intruder to attack the industrial control equipment by tampering ...
