What Does "Always Verify" Mean?
"Always Verify" is a Zero Trust principle requiring continuous verification of every resource access request, regardless of where it originates or who makes it. Unlike traditional security models where verification occurs only at initial login, Always Verify requires verification at every interaction.
This principle includes verification of user identity, device state, request context, and security policy compliance. Verification should occur not only at initial access but also at every subsequent request, context change, or suspicious activity.
Always Verify works in tandem with the "Never Trust" principle, providing multi-layered protection. Even if a user was previously authenticated, the system must continue to verify their access rights and context with every new request.

Principle Implementation
Multi-Factor Authentication
Using multiple authentication factors (password, token, biometrics) for every access request to critical resources.
Contextual Verification
Verifying request context: location, time, device, network, and user behavioral patterns.
Continuous Monitoring
Continuous tracking of user and device activity to detect anomalies and potential threats in real-time.
Adaptive Authentication
Dynamically adjusting verification level based on request risk and access context.
