Tokyo, November 30, 2016 EMitsubishi Heavy Industries, Ltd. (MHI) and Nippon Telegraph and Telephone Corporation (NTT) have completed the joint development of a prototype of “InteRSePT®”*1, a cyber security technology for critical infrastructure control systems. InteRSePT® offers safe and secure system operations using real-time anomaly detection and response for unknown attacks. MHI and NTT aim to apply the newly developed technology in commercial fields such as thermal power generation facilities and chemical plants where continuous availability*2 is of high importance.
Until now, security countermeasures such as IDS / IPS*3 and firewalls*4 have been developed to prevent cyber-attacks caused by malware*5 and DDoS*6. However, in recent years, advanced malware can monitor the operating characteristics and control commands of the target device and change the timing of transmission or parts of commands, causing the target device to fail. MHI and NTT have been working on cyber security research and development since March this year to respond to such threats. The InteRSePT® prototype is a result of this work, combining the high-reliability and safe control technology developed by MHI for the fields of defense and space, and security orchestration technology*7 developed by NTT.
InteRSePT® consists of a network monitoring appliance (NMA) and an advanced security management appliance (ASMA), and monitors real-time data flows in networks in an integrated manner. The system delivers real-time security measures that place importance on availability by changing the security remediation rules on each operating state of the target device. This enables protection against cyber-attacks that exploit control commands, which are difficult to detect and respond to with conventional technology.
Specifically, the system (1) collects and analyzes packets of sensor information flows in the control system network to gain an overall understanding of the operating state; (2) changes the communication control rules of the NMA according to the actual operating state and other factors; (3) analyzes and blocks the packet based on those rules; and (4) aggregates multiple sensor information with the ASMA and monitors the behavior of the entire control system in an integrated manner for early detection. Consequently, it can respond quickly even to unknown cyber-attacks and minimize the damage of such attacks.
Going forward, at MHI’s Cyber Lab, a security development and verification hub located in Tokyo, MHI and NTT will evaluate the technology prototype and verify its adaptability to control systems, to further advance InteRSePT® and expand its application to O&M (operation and maintenance) business.
