Zero Trust is a security framework that eliminates implicit trust and requires continuous verification of every user, device, and application attempting to access resources.
Core Principles
- Verify explicitly - authenticate and authorize every access request
- Least privilege access - limit user access with just-in-time permissions
- Assume breach - design for the worst case, segment and minimize blast radius
- Micro-segmentation - isolate workloads and restrict lateral movement
Implementation Steps
Start with identity and access management (IAM), implement multi-factor authentication (MFA), then apply network segmentation. Zero Trust is a journey, not a single project - prioritize high-value assets first.
