Zero Trust

A security model that continuously verifies identity, device, context, and authorization rather than trusting network location.

Zero Trust is a security model built around explicit verification and least-privilege access. A request is not trusted merely because it originates from an internal network or a previously authenticated device.

Main ideas

Verify user, workload, and device identity.
Evaluate context such as device posture, location, risk, and requested resource.
Grant the minimum access needed for the current task.
Segment resources to limit lateral movement.
Re-evaluate access as context changes.
Log and monitor access decisions.

Zero Trust is not a single product. It is an architecture and operating model that coordinates identity, endpoint security, network controls, policy enforcement, and observability. Poor implementations can create brittle access paths or excessive friction, so policy design and recovery procedures matter as much as enforcement technology.
