 # Tutorial: Monitor your OT networks with Zero Trust principles
 
-[Zero Trust](/security/zero-trust/zero-trust-overview) is a security strategy for designing and implementing the following sets of security principles:
-
-|Verify explicitly  |Use least privilege access  |Assume breach  |
-|---------|---------|---------|
-|Always authenticate and authorize based on all available data points.     | Limit user access with Just-In-Time and Just-Enough-Access (JIT/JEA), risk-based adaptive policies, and data protection.        | Minimize blast radius and segment access. Verify end-to-end encryption and use analytics to get visibility, drive threat detection, and improve defenses.

 Defender for IoT uses site and zone definitions across your OT network to ensure that you're maintaining network hygiene and keeping each subsystem separate and secure.
