Ensure Databases are Encrypted with TDE

SedangLevel 2Otomatismssql

Deskripsi

Ensure user databases are encrypted using Transparent Data Encryption (TDE). Backups of databases encrypted with TDE are automatically encrypted as well. A malicious party who steals physical media like drives or backup tapes can restore or attach the database and browse its data. One solution is to encrypt sensitive data in a database and use a certificate to protect the keys that encrypt the data. This solution prevents anyone without the keys from using the data.
