security-rbac-auth

JWT authentication with RS256 signing and RBAC enables role-based access control by issuing scoped tokens and enforcing resource-level permissions. Define roles, assign policies to resources, validate token signatures, and check permissions at service and data-store boundaries to restrict access by user role.

OAuth handles third-party integrations and delegated access flows; API keys provide simple service-to-service authentication; JWT tokens carry claims and roles for stateless authentication. Choose OAuth for user delegation, API keys for internal services, and JWT for scalable, policy-driven access within your stack.

Enforce org and project boundaries using RBAC policies tied to JWT claims, implement least-privilege roles, isolate data at the service and storage layer, and validate tenant context on every request. Add encryption at rest, secret management, and audit logging to track access across tenants.

Deploy TLS 1.3 for encryption in transit, WAF and rate limiting at the perimeter, CORS policies for cross-origin requests, PII masking in logs, data encryption at rest, and secret management for credentials. Enable audit logging to track all authentication and authorization events.

Yes. Use API keys for service-to-service or development access, JWT tokens for user and delegated access, and OAuth for third-party integrations. Validate each credential type at appropriate layers—API keys at the gateway, JWT at service entry points—and enforce RBAC policies uniformly.

Without RBAC policies, all authenticated users gain the same access level, violating least-privilege principles and creating security risks in multi-tenant or complex permission scenarios. Policy-driven access ensures users access only resources their role permits, reducing blast radius if credentials are compromised.
