## 1. Security Architecture
- Identity-first model with authenticated, scoped access.
- Server-side authorization checks for protected operations.
- Least-privilege access pattern across user and admin functions.

## 2. Cloud Platform Security
- Google Cloud managed security for physical infrastructure and baseline service hardening.
- Regional deployment controls and managed service boundaries.

## 3. Application Security
- Protected API routes require verified bearer tokens.
- User isolation via collection path scoping and authorization checks.
- Defensive error handling to prevent unsafe data leakage.

## 4. Data Security
- Encryption at rest and in transit provided by Google Cloud services.
- Controlled data flows for uploads, notes, and matter operations.

## 5. Storage and Document Security
- Matter-linked document storage with scoped retrieval and upload access.
- Server-validated operations before read/write actions.

## 6. Audit and Traceability
- Cloud audit logging for administrative, read, and write activity on configured services.
- Application-level events and logs for operational observability.

## 7. Reliability and Safety
- Input validation on key routes and controlled fallback behavior.
- Cached read patterns where appropriate to reduce unnecessary exposure and load.

## 8. User Security Features
- Role-aware UI and admin-only controls for privileged paths.
- Workspace indicator and compliance documentation access in-app.

## 9. Recommended Organizational Controls
- Security awareness training, incident response procedures, and periodic access reviews.
- Regular policy updates and legal/compliance review cycles.

## 10. Summary
LegalAI combines cloud-native security controls, scoped authorization, and auditable procedures to support secure legal operations.
