Zero Trust Security Model

TL; DR

Zero Trust is a security framework that assumes no implicit trust and requires verification for every transaction.

Modern identity platforms like Microsoft Entra ID provide key building blocks for Zero Trust implementation.

Core Principles

1. Never trust, always verify - Every access request must be authenticated
2. Least privilege access - Users get minimum required permissions
3. Assume breach - Design systems expecting they will be compromised

Identity & Access Management

• Strong authentication mechanisms
• Conditional access policies
• Privileged access management (PAM)

Device Security

• Device compliance validation
• Mobile device management (MDM)
• Endpoint detection and response (EDR)

Network Security

• Micro-segmentation
• Software-defined perimeters
• Encrypted communications

Data Protection

• Data classification and labeling
• Rights management
• Data loss prevention (DLP)

Benefits

• Reduced attack surface
• Better visibility and control
• Improved compliance posture
• Enhanced data protection
