Zero Trust
Zero Trust is a security model that removes implicit trust from networks: every access request is authenticated, authorized, and continuously validated based on identity, device posture, and context — never on network location.
Core principles
Three rules define the model: verify explicitly (authenticate and authorize every request using all available signals), use least-privilege access (just-in-time, just-enough permission), and assume breach (segment aggressively, encrypt everything, monitor continuously). Perimeter defenses and VPN-style broad network access give way to per-resource, identity-bound decisions.
In cloud environments this lands concretely in IAM design: scoped-down policies, no wildcard actions, conditions on source and principal, and short-lived credentials — the same failure patterns our IAM Policy Validator flags automatically.
Where it fits with standards
Zero Trust is an architecture, not a certifiable standard — but its controls map cleanly onto ISO/IEC 27001 Annex A access-control, logging, and network-security controls, and onto NIST SP 800-207, the reference architecture most implementations follow.
