18In the Internet of Things (IoT) era, many sensors and other devices will be deployed in our surroundings and connect-ed to networks. They will allow us to lead more convenient and ‘smart’ lives. However, security measures for guarantee-ing the safety of such devices are becoming a pressing issue behind the scenes. The scope that cybersecurity should cover is expanding daily; in particular, it must be able to protect people from information leaks and privacy violations when big data collected from such IoT devices is utilized. The Cybersecurity Research Institute conducts research and development (R&D) on how to deal with the latest pressing concerns and emergent issues in our information society. The Cybersecurity Research Institute consists of the Cybersecurity Laboratory and Security Fundamentals Laboratory. The Cybersecurity Laboratory conducts R&D on advanced cybersecurity technol-ogies and security testbed development and operations technology, while the Se-curity Fundamentals Laboratory conducts R&D on cryptographic technologies.Advanced cybersecurity tech-nologiesWe conduct R&D on monitoring cyber-attacks and analyzing the increasingly so-phisticated and evolved cyberattacks against government and other important infrastructure. We also engage in research that involves collecting and analyzing huge amounts of data from these diverse attacks in order to develop automatic countermeasures. We strive for the quick deployment of our R&D outcomes by verifying them on NICT’s own cyber inci-dent response system. In order to rein-force the capability of responding to cy-berattacks against governments or critical infrastructure, we carry out R&D on visualization-driven security operation techniques and machine-learning-based Fig.1 : NIRVANA-KAIVisualization of defensive actuation in NIRVANA-KAI to isolate an infected class C address.CybersecurityCybersecurity Research Institute Research and Development
