# Security Review

Your integration must meet FinHub's security requirements before production access.

## Security Checklist

### Authentication & Authorization

| Requirement           | Description                                  |
| --------------------- | -------------------------------------------- |
| Token Storage         | Tokens stored securely (not in localStorage) |
| Token Refresh         | Proper token refresh implementation          |
| Session Management    | Secure session handling                      |
| Credential Protection | Client secrets not exposed                   |

### Data Protection

| Requirement       | Description                      |
| ----------------- | -------------------------------- |
| TLS/HTTPS         | All communications over HTTPS    |
| Data Encryption   | Sensitive data encrypted at rest |
| PII Handling      | Personal data handled per GDPR   |
| Data Minimization | Only necessary data collected    |

### API Security

| Requirement      | Description                        |
| ---------------- | ---------------------------------- |
| Input Validation | All inputs validated               |
| Rate Limiting    | Client-side rate limiting          |
| Error Handling   | Errors don't expose sensitive info |

## Common Security Issues

1. **Storing tokens in localStorage** - Use secure HTTP-only cookies
2. **Exposing client secrets** - Keep secrets server-side only
3. **Logging sensitive data** - Never log passwords, tokens, or PII
4. **Hardcoding credentials** - Use environment variables

## Security Assessment Process

1. **Self-Assessment** - Complete the security checklist
2. **Submit Documentation** - Provide security architecture docs
3. **FinHub Review** - Security team reviews submission
4. **Remediation** - Address any findings
5. **Approval** - Receive security clearance
