英文要約Development item: R&D for operation monitoring and analysis technologies of control and communication devices and networks

R&D Overview, results
Research and development on log/traffic analyzing technologies that enable to, in an effective and an efficient manner, confirm soundness of machines/devices which are involved in information and control network (INF-NW), IoT network (IoT-NW) and control network (CTL-NW) are carried out. These technologies consist of results of the following three development items, and in 2015, a requirement document for system and technology prototyping was developed.

1. R&D for soundness confirmation technologies of INF-NW
This R&D studied an analysis function within a target machine/device and within an aggregated facility, which monitors operations of INF-NW and associated control and communication devices and identifies an existence of backdoors. A real time log collection function following network traffic variation and an innovative monitoring function and control function following a new capability were studied.
Study key aspect:
・Definition of basic functions of collection part, storage part, soundness analyzing part and control part as function blocks of soundness confirmation technology.

2. R&D for soundness confirmation technology of IoT-NW
2 -1. R&D for soundness confirmation technology using log/traffic from/to IoT devices
The following issues which relate to soundness confirmation technology of IoT devices which compose IoT-NW connecting to INF-NW.
(1) Consideration for various IoT devices without corresponding detection logic
(2) Consideration for feature amount of various attacks caused by new attack type generations
Anomaly detection technologies for the IoT devices in IoT-NW connected with single INF-NW and also with multiple INF-NW were studied. Study key aspect:
・Studies on business logic for soundness confirmations of IoT-NW connecting to both a single INF-NW and multiple INF-NWs.

2-2. R&D of soundness confirmation technology by IoT-GW
The following studies were carried out to realize operation monitoring and analyzing functions of IoT devices.
(1)Effective collection, management and statistical processing functions of traffic information needed for monitoring and analyzing
(2) Implementation of soundness degradation detection function on IoT-GW
Study key aspect:
・Description of functional requirements of soundness confirmation technology which is used for development of IoT-GW prototype.

3. R&D for soundness confirmation technology of CTL-NW
Developing innovative analysis model which enable to integrate area specific knowledge and common knowledge spanning multiple areas of control systems for a critical infrastructure, continuously evolving operation monitoring and analysis technologies were studied.
In detail, the following issues are studied to confirm soundness of a system which spans to CTL-NW:
・Difficulty of anomaly detection caused by a targeted attack which uses normal tools in INF-NW;
・Difficulty of soundness model creation for anomaly detection in CTL-NW.
Study key aspect:
・Research on communication specifications of INF-NW and CTL-NW in critical infrastructure was performed.
