Is OAuth consent authorization?

OAuth consent is a delegation of access to a client. It is one authorization pattern, not a full transaction-approval model.

Does Zero Trust replace authorization design?

Zero Trust emphasizes continuous verification. You still need explicit policies for actions, especially irreversible ones.

Authorization

Definition

Authorization evaluates a policy against a principal, an action, a resource, and context. It happens after authentication, or continuously as context changes.

Authorization

Why it matters

Most damaging incidents involve a valid identity doing something it should not: over-privileged APIs, standing admin roles, or agents inheriting user tokens.

Authorization

How it works

RBAC assigns permissions to roles. ABAC evaluates attributes. Policy-based systems (PBAC) express decisions as rules. Fine-grained authorization scopes actions, not just applications.

Transaction authorization is a special case: the resource is a specific operation with an amount, beneficiary, or irreversible effect.

Authorization

Human authorization

When an AI agent or workload can initiate an action, the unanswered question is: who authorized it? That is not solved by role membership alone. See Human Authorization.

Authorization

Limitations

A correct allow decision can still be wrong if identity was stolen. Authorization cannot replace authentication, device integrity, or fraud analytics.

Authorization

Where this meets Keyra

Keyra's published language around Human Authorized Intelligence™ is specifically about binding actions to human approval. Do not infer a general-purpose policy engine from that positioning.
