Benefits of technology

The technical effect of this inventor's new technology can include improvements such as improved efficiency or reduced energy consumption compared with existing technologies like traditional heating systems used for industrial processes.

Problems solved by technology

This technical problem addressed in this patents relates to improving security measures against attacks caused within industrial networks due to advanced threat agents like hackings. These methods involve analyzing large amounts of data transmitted over various communication links between devices called nodes during normal operations without being able to detect any unusual patterns related to those connections. Current solutions require manual intervention with significant effort and have limitations in terms of precision and effectiveness.

Abstract

The embodiment of the invention belongs to the technical field of network security, and provides a communication data detection method and device for a network, and a machine-readable storage medium.The method comprises the following steps: receiving communication data, wherein the communication data comprises a data message with an effective load; and sequentially carrying out matching on the length of the effective load, a fixed field of the effective load and a variable field of the effective load based on at least one data detection model, and determining that the data message is abnormalwhen the matching on any of the above items fails. The communication data detection method and device for the network and the machine-readable storage medium have the advantage that communication data abnormalities can be detected in a real-time manner without network protocol pre-analysis.
