Zero Trust Applied to AI Systems: The Per-Request Identity, Policy, and Audit Boundary
Zero-trust architecture replaces the perimeter assumption with per-request verification of identity, device, and policy. Applied to AI systems, the same principle moves the verification to the AI request boundary: who is making the call, what classification the request carries, what policy version evaluates the call, and what audit record the layer commits. This piece walks through the four zero-trust principles and how each one maps to a concrete decision the AI request path has to commit on every call.
