Outline of Final Research Achievements

We proposed a new structure for Level 2 networks as "fog", which is to prevent external access to the controllers, which would cause a physical accident if manipulated by a cyber attacker, and to virtualize the network in the plant site and securely connect it to a Level 3 or higher network that has been moved to "cloud".
We developed the technologies to realize "fog". One is SDN technology that, when it detects a possible attack, does not simply block it, but isolates the controller and leads it to a sandbox to ensure safety and acquire information on the attacker. Second is a risk assessment system to evaluate the risk of observed abnormality considering vulnerabilities in "fog". We propose to apply encrypted OPC-UA communication in "fog". Encryption makes communication secure, but it does not prevent the transmission of dangerous commands to the controller, so we developed a system to monitor the communication contents in encrypted communication.

Academic Significance and Societal Importance of the Research Achievements

サイバー攻撃は、工場設備にも及んでおり、甚大な事故が発生する可能性もある。サイバー攻撃の高度化は著しく、各社、各事業所で、セキュリティ対策の人員体制の確保はますます困難になっている。オフィス環境もクラウドに移行しているが、操業現場もクラウド、仮想環境などを駆使した新たな操業体制が望まれる。そこでの事業所のネットワークの構造のあるべき姿と防御方法について提案した。
ここでの提案は、現在世界で進行しているIndustrie4.0やOpen Process Automationにも適合する概念であるとともに、ネットワーク構造や監視、対応に対する具体的で新規な技術を示すものである。
