Transparent Data Encryption / TDE in SQL Server: enable, keys & certificates, backups, restore

However, in a scenario where the physical media (such as drives or backup tapes) are stolen, a malicious party can just restore or attach the database and browse the data. One solution is to encrypt the sensitive data in the database and protect the keys that are used to encrypt the data with a certificate.
