Zero Trust is not a single product. It is a staged approach to verifying every request, every action, every identity. The Mosh model breaks this journey into clear, measurable phases, each with explicit requirements and outcomes.
Phase 0: Implicit Trust
Legacy networks often assume everything inside is safe. Access controls are coarse. Monitoring is thin. Attackers exploit this blind spot.
Phase 1: Identity Verification
Every user, device, and service must prove who they are before getting access. This means strong authentication, strict key management, and centralized identity handling.
Phase 2: Contextual Access Control
Authorization is based on context—location, device compliance, risk signals. Policies adapt in real time. Unauthorized behavior is blocked immediately.
Phase 3: Continuous Monitoring
Traffic, logs, and behavior are inspected at every stage. Alerts are not optional. Data flows are mapped. Security becomes an active, always-on system.
