Zero trust conceptual architecture views security controls as an identity- and policy-driven model rather than a network perimeter model.

• Users
• Devices
• Infrastructure
• Applications
• Identity services
• Policy enforcement points
• Access decision engines
• Security monitoring

The architecture ensures that access decisions are based on user identity, device posture, context, and application-level policy rather than location alone.

The slide references the Microsoft Zero Trust model and modern security architecture patterns.
