Zero Trust is a security paradigm that assumes breach and verifies every access request, regardless of origin.
Core Principles
- Never trust by default: Even internal traffic requires authentication
- Always verify: Every user, device, and connection must be authenticated and authorized
- Minimize blast radius: Microsegmentation limits lateral movement
- Protect data: Encryption and monitoring at every layer
Implementation Components
- Identity and access management (IAM)
- Device health verification
- Network microsegmentation
- Data encryption and classification
- Continuous monitoring and logging
Benefits
- Reduced breach surface area
- Better visibility into user behavior
- Faster detection of anomalies
- Compliance with modern frameworks
