This session will focus on the importance of OT security and the latest threats. As the industry continues to digitalize, cyber-attacks on OT environments are on the rise, requiring the entire supply chain to respond. In order to increase the security and safely operate OT environments such as factories, it is necessary to visualize all devices and communications within the OT environment, understand the overall situation, and detect suspicious activities and attacks. It is important to detect in real time so that we can respond quickly when an abnormality occurs. This session will provide an overview of the security solutions that make these possible, as well as introduce NTT Communications' efforts to securely provide security solutions.
