MHI and NTT Group Begin Sales of "InteRSePT" Cyber Security Technology Providing Safe and Secure Operation of Control Systemse

- Advanced Security at All Operating States with Low Cost and Space Savings -

TOKYO, Apr 25, 2018 - (JCN Newswire) - Mitsubishi Heavy Industries, Ltd. (MHI), Nippon Telegraph and Telephone Corporation (NTT), NTT DATA Corporation (NTT DATA), and NTT Communications Corporation (NTT Com) have commercialized "InteRSePT(R)"(1), a jointly developed cyber security technology for critical infrastructure control systems. InteRSePTInteRSePT(R) provides real-time anomaly detection and response for unknown cyber-attacks, contributing to safe and secure system operations. Sales of the system will begin in May. MHI and NTT are actively developing markets for the technology in commercial fields where continuous availability(2) is critical, such as thermal power generation facilities and chemical plants.

1. Background to the Development

In addition to the existing security countermeasures, such as IDS / IPS(3) and firewalls(4) to prevent cyber-attacks from malware(5) and DDoS(6), in recent years measures have become necessary to counter advanced cyber-attacks that monitor the operating characteristics and control commands of the target device, and change the timing of network communication or contents of commands to cause the target device to fail.

MHI and NTT, in response to growing needs, began research and development on security technologies in March 2016. The InteRSePT prototype was completed in November that year, combining the highly reliable and safe control technologies developed by MHI for the fields of defense and space, with security control technology(7) developed by NTT.

Evaluation of the prototype and conformance testing for control systems was then conducted at Cyber Lab, MHI's facility in Tokyo for security development and testing. The functionality of InteRSePT was further improved and the range of applications broadened to include the operations and maintenance (O&M) businesses. This led to commercialization and the launch of sales.

2. Features of InteRSePT

InteRSePT comprises a real-time network monitoring system (RNMS) and a security management system (SMS). The system monitors sensor information and other data flows in networks in an integrated manner, and detects cyber-attacks that exploit control commands, which are difficult to detect and respond to with conventional technology. By changing the security remediation rules on each operating state of the target device, the system provides early detection of anomalies, and allows for a rapid response to even unknown cyber-attacks while maintaining availability. (Joint patent pending)

InteRSePT is able to provide detailed confirmation of control system networks, and offers exceptional compatibility with a wide range of industrial facilities and devices.

1) The system collects and analyzes packets of sensor information flows in the control system network to determine the operating state.
2) The communication control rules of the RNMS are changed according to the actual operating state and other factors.
3) Packets are analyzed, and blocked or passed based on the rules.
4) Multiple sensor information is aggregated in the SMS, and the behavior of the entire control system monitored in an integrated manner to allow for early detection (behavior detection processing(8)), and a rapid response to even unknown cyber-attacks.

3. Productization

For the productization, RNMS utilizing commercial-off-the-shelf hardware and integrated with network switch provides low cost, space savings and easier system installability. In addition, the SMS improved its behavior detection processing speed by adopting distributed processing.

4. Role of each company

Sales of InteRSePT
Development of data analysis, operational status estimates, and anomaly detection methods according to the control system, as well as handling and recovery methods, and design optimization

Provide security control technology and RNMS developed by the NTT,

Support market development for security solutions based on the InteRSePT system developed by MHI and the NTT Group

Development of technologies related to data accumulation and anomaly detection necessary for market application of the NTT's core technologies, and productization of security solutions

5. Future plans

Going forward, MHI NTT, NTT DATA, and NTT Com will cooperate to promote InteRSePT' low cost, advanced functionality, fast processing capabilities, and easy installability to a wide range of industries, as well as propose individual security solutions, and develop markets.

Further, we will effectively utilize the aggregated and analyzed sensor data from InteRSePT to not only security countermeasures but also operational parameters optimization and preventive maintenance to reduce time required for maintenance. We will develop an O&M total solutions business to help enhance operational efficiency for customers.
