Tenant Scoped Api Authorization — Air gapped
Reference architecture for implementing tenant scoped api authorization in a air gapped deployment context. Includes trust boundaries, authorization flow, evidence flow, and deployment-specific considerations.
Architecture Overview
- Architecture ID
- tenant-scoped-api-authorization-air-gapped
- Status
- SUPPORTED
- Deployment Context
- air-gapped
- Intended Use
- Implement tenant scoped api authorization as part of an enterprise trust infrastructure, providing authorization, evidence, and verification capabilities for AI system operations
Components
Titan Handshake (authentication), Titan Verify (evidence validation), Titan Sign (cryptographic signing), Titan Forge (inventory attestation), offline verification module, local signing authority, manual certificate distribution
Trust Boundaries
Tenant isolation boundary, authorization-scope boundary, evidence-integrity boundary, and signing-authority boundary
Operational Flows
Authorization Flow
Client authenticates via Titan Handshake, receives scoped authorization token, presents token for each operation, authorization verified at each component boundary
Evidence Flow
Operations generate receipts, receipts collected into evidence packages, packages verified by Titan Verify, verified packages eligible for certification via Titan Sign
Signature Flow
Evidence packages submitted to Titan Sign, signature applied with tenant-scoped signing key, signed packages stored with verification metadata, public verification endpoint exposes certificate status
Tenant Boundary Behavior
Strict tenant isolation enforced at authorization layer. Each tenant operates within a scoped boundary. Cross-tenant operations are denied by default. Evidence packages are tenant-scoped and cannot reference cross-tenant data.
Vallum Responsibilities
Maintain authorization infrastructure, enforce tenant isolation at the authorization layer, generate and store evidence packages, provide verification endpoints, and maintain signing-key security
Failure Modes
Authentication failure (denied access), authorization scope violation (operation blocked), evidence integrity failure (package rejected), signature failure (certification denied), and verification endpoint unavailability (status unknown)
Deployment Limitations
No real-time verification possible. Certificate status requires manual synchronization. Evidence packages must be transported physically. No automated revocation propagation.
Evidence Produced
Authorization receipts, operation evidence packages, and signed records specific to the tenant scoped api authorization pattern in a air gapped context
Evidence NOT Produced
Infrastructure provisioning records, network configuration evidence, physical security documentation, and air gapped-specific platform logs
Your Responsibilities
Implement complete infrastructure stack, manage air-gap boundaries, handle offline certificate distribution, and maintain all operational and security responsibilities independently
