Data security is solely the responsibility of the network security team and does not require any specific features within Delta Lake.

Implementing role-based access control (RBAC) and encryption for data at rest and in transit within Delta Lake ensures that only authorized personnel can access sensitive financial data, thereby protecting against unauthorized access and meeting compliance requirements.

Data security in Delta Lake is automatically handled by the cloud provider, requiring no additional configuration or management by the organization.

The primary focus of data security in Delta Lake is on performance optimization, with security features being secondary and not critical for financial data.
