Hitachi Review

Highlight

By connecting various devices to a network and enabling data gathering and analysis, the IoT is expected to contribute to the creation of new customer value. Critical infrastructure that affects people’s lives and economic activities will also become an area in which the IoT is used, so security measures for IoT systems are very important. On the other hand, a dramatic increase in the number of connected devices will create technical problems such as attacks with a broader scope of influence and attacks that last longer. So, a shortage of security operations administrators will also be a problem. This article focuses on availability, which is one of the key requirements for IoT security for critical infrastructure. The article presents approaches for proceeding quickly from problem detection to provisional measures to ensure availability, and detection technology developed by Hitachi that has high sensitivity and a low rate of false positives.
