Answer
Multi-tenant API security includes:
- Tenant ID in claims or headers
- Middleware-based access validation
- Database filtering by tenant context
Quick Answer
Multi-tenant security: include tenant ID in JWT claims. Validate tenant claim on every request. Filter all DB queries by tenant ID (row-level security or query filters in EF Core). Use separate schemas or databases per tenant for stronger isolation. Prevent tenant data leakage in error messages. Audit cross-tenant access attempts. Use EF Core global query filters to automatically apply tenant filtering.
