Industrial robot system security threat evaluation method based on time-sharing frequency

Abstract

The invention discloses an industrial robot system security threat evaluation method based on time-sharing frequency. The method comprises the following steps of: S1, recognizing potential threats of an industrial robot system according to system logs, historical behaviors and other information, classifying the threats according to a threat expression form, and determining a threat subject and a threat approach; S2, aiming at a threat behavior selected by the industrial robot system, counting occurrence frequency of the threat behavior in a historical period, and forming a threat frequency sequence diagram of the industrial robot system; S3, performing segmentation processing on the total statistical time of the occurrence frequency of the threat behavior, selecting multiple experts to evaluate the threat frequency, and sequentially evaluating the threat frequency in different time periods by each expert; and S4, calculating a threat frequency evaluation result trust weight of each expert, forming a threat frequency vector, and realizing threat assignment of the industrial robot system. According to the method, security threat evaluation can be carried out on the industrial robot system with a relatively long historical security threat behavior record.

Description

technical field [0001] The invention belongs to the field of information security risk assessment and relates to a time-sharing frequency-based security threat assessment method for an industrial robot system. Background technique [0002] With the gradual acceleration of the intelligent construction of factories, industrial robots integrate advanced technologies such as machinery, electronics, sensing, and control. They have not only become important automation equipment in modern manufacturing, but also become flexible manufacturing systems, automated factories, and computer integrated manufacturing systems. Indispensable automation tool. However, while the informatization and networking of the manufacturing industry improves the overall work efficiency of factories, it also inevitably increases the possibility of information security incidents. Malicious attackers take advantage of the potential vulnerabilities of industrial robot systems to launch threats to The manufac...
