Data encryption is very important because it’s a way to protect the current and the archived data in order to ensure its confidentiality. This prevents an unauthorized access and usage. In this article, I will briefly present some important aspects of data encryption and decryption.
If you need to store confidential data in your database, you can use data encryption. SQL Server supports encryption with symmetric keys, asymmetric keys, certificates, and password phrases. I assume that you, the reader, are already familiar with these terms. In this article, I will focus on two out of many encryption options provided by SQL Server:
- Transparent Data Encryption (TDE)
- Always Encrypted (AE)
To manage the data security that has been backed up by the file system as a database backup files, SQL Server provides the backup encryption feature. In this article, we will talk about encryption options available in SQL Server for database backups. We will have a closer look at the usage details, benefits, and recommended practices for encrypting SQL Server database backup during the backup process. (more…)
