## Data Isolation & Security Architecture

### Complete Multi-Tenant Isolation

TIKSIG implements defense-in-depth isolation to ensure no cross-tenant data leakage:

#### Database Layer
- PostgreSQL row-level security (RLS) policies on all tenant-scoped tables
- Every query is automatically filtered by `tenant_id`
- No shared tables for sensitive data — each tenant's data is logically partitioned
- Foreign key constraints enforce referential integrity within tenant boundaries

#### Application Layer
- Middleware extracts and validates tenant context from authenticated sessions
- All service methods receive tenant context as a required parameter
- Cross-tenant access attempts are logged and blocked at the service level

#### Cache Layer
- Redis key namespacing: `tenant:{tenantId}:resource:{resourceId}`
- TTL policies prevent stale cross-tenant cache entries
- Cache invalidation is scoped to individual tenants

#### File Storage Layer
- Tenant-scoped MinIO/S3 bucket prefixes
- Pre-signed URLs are generated with tenant-scoped access policies
- No shared file paths between tenants

#### API Layer
- API keys are scoped to a single tenant
- Rate limiting is applied per-tenant to prevent resource monopolization
- IP whitelisting can be configured per API key

### Audit & Compliance
- Every administrative action is logged with: actor, action, resource, timestamp, IP address
- Audit logs are immutable and tenant-scoped
- Data retention policies are configurable per tenant
- GDPR data export and deletion workflows are built in
