# 6. Security Considerations

**6.1 Data Privacy**

* **Encryption**: Data in transit and at rest is encrypted to protect sensitive information.
* **Access Control**: Use role-based access control to enforce permissions on chaincode.

**6.2 Network Security**

* **Identity Management**: Leverage certificate authorities (CAs) to issue digital certificates for users and nodes.
* **Audit Logging**: Maintain logs of all transactions for compliance and monitoring.
