Designing a Robust Defense for Operational Technology Using Azure Defender for IoT
Operational Technology presents many special challenges from a security perspective. The most effective way to improve security is to monitor and analyze network traffic. Since this can be done non-intrusively in most circumstances, it flies 'below the radar' of the OT traffic and can provide valuable insights into network design, assets, machine configuration and potential threats. As a control system engineer, I designed, commissioned and refined complex Distributed Control and Programmable Logic control systems used in power production for many years. Gradually my role transitioned to one of securing these systems from cyber attack. In a large public utility, I developed the strategy and implemented the changes necessary to make this possible. I hope you find my insights valuable and actionable. I would love to hear from you, e-mail me at v-henrysierk@microsoft.comAzure Defender for IoT is now in public preview
Azure Defender for IoT is now available in public preview for on-premises deployments, with the option of connecting securely to Azure Sentinel to eliminate IT/OT silos and provide a unified view of threats across both IT and OT environments. It also integrates out-of-the box with third-party tools like Splunk, IBM QRadar, and ServiceNow.
