Method for Analyzing and Detecting Security Threat of Operational Technology Data

摘要

The security threat analysis and detection method of operational technology data according to the present invention includes an operational technology data collection unit that collects operational technology data, a data storage unit, and analyzes the operational technology data collected by the operational technology data collection unit and detects threats A first step is performed by an analysis detection framework system including an analysis detection unit to detect, the operation description data collection unit receiving a building network packet; a second step of extracting, by the operation description data collection unit, data included in the network packet received in the first step and storing it in a data storage; and a third step in which the analysis detection unit analyzes the data stored in the data storage in the second step and detects a threat.
