What is the role of security information and event management (SIEM) in OT security?

Security Information and Event Management (SIEM) plays a crucial role in enhancing Operational Technology (OT) security monitoring by providing a centralized platform for collecting, analyzing, and monitoring security events and data from various sources within an OT environment. SIEM systems help in detecting and responding to security incidents in real-time, enabling organizations to have better visibility into their OT systems and networks. By correlating data from different sources, SIEM can identify potential security threats, anomalous activities, and vulnerabilities within OT infrastructure. Furthermore, SIEM can aid in compliance management by generating reports and alerts that help organizations adhere to regulatory requirements and security best practices in their OT operations.
