Correct arrangement
- Secure Socket Layer (SSL)
- Transparent Data Encryption (TDE)
Explanation
SSL (Secure Socket Layer) encrypts data in transit between clients and the SQL Server database engine, preventing interception of T-SQL statements over the network with minimal processor overhead compared to application-level encryption. Transparent Data Encryption (TDE) encrypts the physical database and log files at rest at the page level, meaning that if the files are physically moved to another disk or server, they remain encrypted and unreadable without the proper certificates - this directly satisfies the second requirement. TDE is preferred over EFS or BitLocker for database file encryption because it is SQL Server-native, operates transparently, and is specifically designed to protect data files and log files with minimal administrative and processor overhead.
