Zero Trust is a security model that assumes no implicit trust, regardless of whether the request comes from inside or outside the network. Every access request must be verified.
Core Principles
- Verify explicitly - Always authenticate and authorize based on all available data points
- Least privilege access - Limit user access with just-in-time and just-enough-access
- Assume breach - Minimize blast radius and segment access to verify end-to-end encryption
Implementation Steps
Start with identity verification, implement micro-segmentation, deploy continuous monitoring, and ensure strong encryption for all data in transit and at rest.
