WPT 01What is Zero Trust?
Zero Trust is a security model based on the principle of "never trust, always verify." Unlike traditional perimeter-based security, Zero Trust assumes that threats can come from anywhere—inside or outside the network.
WPT 02Core Principles
1. Verify Explicitly
Always authenticate and authorize based on all available data points:
- User identity
- Location
- Device health
- Service or workload
- Data classification
2. Use Least Privilege Access
Limit user access with just-in-time and just-enough-access (JIT/JEA):
- Implement role-based access control (RBAC)
- Use time-limited access
- Implement attribute-based access control for fine-grained permissions
3. Assume Breach
Minimize blast radius and segment access:
- Implement microsegmentation
- Use end-to-end encryption
- Use analytics for threat detection
WPT 03Implementation Steps
Phase 1: Identity
Start with strong identity management:
- Implement multi-factor authentication (MFA)
- Use single sign-on (SSO)
- Deploy identity governance
Phase 2: Devices
Ensure device compliance:
- Implement device health checks
- Use endpoint detection and response (EDR)
- Enforce device encryption
Phase 3: Network
Segment your network:
- Implement microsegmentation
- Use software-defined perimeter
- Deploy network access control
WPT 04Conclusion
Zero Trust is not a product but a strategy. Implementation is an ongoing journey that requires commitment from all levels of the organization.
