# Security Considerations

Security is central to the Verifier’s design, ensuring trust and privacy throughout the verification process:

1. **Transport Security**:\
   All communication occurs over HTTPS, safeguarding data in transit.
2. **Nonce and State Parameters**:\
   Verification requests incorporate unique, time-bound values to prevent replay attacks.
3. **Client Authentication**:\
   The `clientSecret` authenticates the relying party to the Verifier Service. Store it securely and never expose it client-side.
4. **Credential Integrity**:\
   The Verifier checks cryptographic signatures and DID Documents, rejecting credentials that fail authenticity or integrity checks.
5. **Minimal Data Exposure**:\
   The Verifier only processes essential data. It does not store unnecessary information, preserving privacy.
6. **Monitoring and Logging**:\
   Maintain logs and monitor for suspicious activities, such as repeated failed verifications.
7. **Error Handling**:\
   Avoid exposing sensitive details in error responses. Provide generic user-facing messages and log technical details internally.

By following these security practices and integrating them into your application’s operations, you maintain a robust, trusted environment for all stakeholders.
