NTT Communications (NTT Com) announced the launch of a new cloud-based security service, the “OsecT” wide-angle professional service, to visualize and detect security risks in control systems supporting factory production lines, etc., mainly for SMEs.
NTT Com aims to capture a 10% share of the SME market for control-system security services by the end of the current fiscal year in March 2023.
OsecT's visualization function clarifies device connection configurations while the detection function recognizes any abnormality, enabling detected problems to be addressed immediately. By collecting, storing and analyzing control-system data in the cloud, the service is able to visualize device operating systems and connection configurations, and then detect anomalies such as unknown device connections or unnatural communication data rates. A dedicated portal site can be used to view visualization and detection status remotely.
Service subscription costs just 60,000 yen per month (66,000 yen with tax) for all necessary functions, including simplified reports adjusted to each customer’s needs based on preliminary discussion. Application is possible through an NTT Com sales representative or via the ICT Business Mall e-commerce site for corporate customers (Japanese only; see below). System sensors are provided preconfigured, so clients do not require special know-how or expertise and the system can be introduced easily. Deployment does not interfere with production-line operations
Since the client’s existing control system does not require reconfiguration, OsecT can be introduced without affecting production-line operations. Moreover, data collection, storage and analysis is not sourced from the control system but instead from existing data in system communication paths, so the control system CPU is not burdened with extra processing. Reviews effectiveness of security measures and enables prompt responses to anomalies
Visualization enables devices or communication paths that require more robust security to be identified for consideration of more effective measures. The detection function alerts clients to abnormalities in real time, enabling rapid responses. Safe visualization and detection of confidential data without fear of leakage or eavesdropping
Sensitive data, such as production-line control information, is excluded by sensors. The configuration1 of the communication network for uploading data to the cloud incorporates both IoT Connect Mobile Type S,2 a mobile data-communication service for IoT, and the Flexible InterConnect3 service for data transmission within a closed network. Confidential data is encrypted for safe visualization and detection without fear of leaks to outside parties or eavesdropping.
