A security blueprint for multi-tenant AI operations

Resolve the tenant from an authenticated server session or validated public channel mapping, never an untrusted browser field. Apply scope to database queries, cache keys, queues, storage, retrieval, analytics, and provider credentials.

Tests should attempt reads and writes across two tenants in both directions. For mutations, verify the foreign record remains unchanged.

Navigation and disabled buttons improve usability, but they are not security controls. Every endpoint must authorize platform administrators, tenant administrators, and staff according to its real impact.

Test hidden routes, guessed identifiers, nested resources, exports, signed URLs, provider tests, deletes, and configuration mutations. Return a consistent forbidden response without revealing foreign resources.

Encrypt API keys, tokens, SMTP passwords, webhook secrets, and signing material at rest. Mask secrets in responses and logs, restrict decryption to the integration runtime, and maintain rotation metadata.

Use short-lived credentials where supported. A connection test should prove the expected account and scopes without returning the secret to the interface.

Tag knowledge chunks with tenant, source, visibility, lifecycle, and version metadata. Apply authorization before retrieval and again before presenting citations or taking action.

Document which providers receive prompts, attachments, and tool results, with retention and regional settings. Give tenants explicit controls over approved models and sensitive data.

Platform support should default to metadata-only diagnostics. Time-bound elevated access needs a reason, approval where appropriate, strong authentication, a visible tenant indicator, and complete audit events.

Avoid shared credentials and silent impersonation. Tenants should review who accessed configuration, what changed, and when access expired.

Retain authentication events, authorization denials, configuration changes, secret rotations, provider health, AI tool actions, approvals, and exports according to policy. Protect audit records from ordinary mutation.

Practice credential compromise, cross-tenant access attempts, provider outages, webhook replay, deletion requests, and suspicious automation. Readiness includes detecting, containing, explaining, and recovering.
