How can the MedicalHistory data in the ClaimsDetail table be secured?

Transparent Data Encryption (TDE) is an effective method for securing sensitive data like MedicalHistory in the ClaimsDetail table because it encrypts the entire database, including the data files, log files, and backups, while they are stored on disk. This encryption helps protect the data from unauthorized access at the storage level without requiring any changes to the applications accessing the data. TDE provides a layer of security against potential breaches where someone could gain access to the physical storage media.

On the other hand, data masking modifies data to protect sensitive information while maintaining its usability in non-production environments, but it does not secure data at rest. Access control lists (ACLs) manage permissions to files or objects but do not encrypt data to protect it from unauthorized access. Backup encryption is vital for securing backup copies of data but does not directly secure the data in the live database. Therefore, using TDE is the most comprehensive and effective approach to securing MedicalHistory data in the ClaimsDetail table.
