D. Passive Traffic Monitoring:

Passive traffic monitoring involves observing network traffic without actively scanning or disrupting devices. This approach aligns with Zero Trust principles by allowing you to gain insights into the behavior of devices without introducing potential risks associated with active scanning. It helps in understanding the normal traffic patterns and identifying anomalies or suspicious activities without impacting the operation of OT and IoT devices.
A. Threat Monitoring:

Threat monitoring is essential for actively monitoring and analyzing security events to detect and respond to potential threats. Implementing threat monitoring aligns with Zero Trust principles by continuously assessing the security posture of OT and IoT devices. This proactive approach enables the identification of security incidents and allows for timely responses to mitigate risks, all while minimizing disruptions to business operations.
