SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PowerX STS provides tenant-scoped authentication through a token-exchange mechanism for plugins. It supports gRPC/HTTP transport, a shared KeyRing, and per-tenant credentials with rotation. It enforces TTL/aud/scope validations and integrates with auditing for secure plugin interactions.

Core Features & Use Cases

  • STS Exchange: issues short-lived JWTs from client_id, client_secret, aud, scope, ttl for per-tenant plugins.
  • KeyRing & Interceptors: share HS256 keys across STS and gRPC interceptors for consistent validation.
  • Auditing & Rotation: per-tenant credential rotation, audit logs, and strict access control for plugin operations.
  • Use cases include onboarding new plugins, cross-plugin auth, and secure tenant isolation in multi-tenant deployments.

Quick Start

Deploy the STS service and configure a tenant plugin to perform token exchanges and validate tokens through the gRPC metadata authentication.

FAQPage Schema
How does token-exchange authentication work for multi-tenant plugins?

Token-exchange for multi-tenant plugins issues short-lived JWTs from client credentials. It enforces TTL, audience, and scope validations to ensure secure tenant isolation. Per-tenant credentials are rotated and tracked through audit logs for plugin interactions.

How do I issue short-lived JWTs for gRPC plugin authentication?

To issue short-lived JWTs for gRPC plugin authentication, deploy an STS service to exchange client_id, client_secret, aud, scope, and ttl. The service shares HS256 keys via a KeyRing with gRPC interceptors for consistent metadata validation.

Can I use HTTP transport instead of gRPC for tenant-scoped token exchange?

Yes, tenant-scoped token exchange supports both gRPC and HTTP transport. This flexibility allows plugins to authenticate via short-lived JWTs and validate access credentials across different communication protocols in multi-tenant deployments.

What is the best way to handle credential rotation and auditing for plugins?

The best way to handle credential rotation and auditing for plugins is using a tenant-aware STS. It enforces strict access control, logs operations for auditing, and rotates per-tenant credentials automatically to maintain secure cross-plugin authentication.

Do I need a shared KeyRing to validate tokens across gRPC interceptors?

Yes, a shared KeyRing is required to validate tokens across gRPC interceptors. Sharing HS256 keys between the STS and interceptors ensures consistent validation of short-lived JWTs and enforces strict access control for tenant plugins.
