Protecting your database using Transparent Data Encryption in SQL Server 2008

Encryption:
Encryption is the process of transforming information in plain text using a cipher, or algorithm, to make it unreadable to everyone other than the person who has the key. There are two types of keys; symmetric and asymmetric. When the same value is used to encrypt and decrypt, then it is known as a symmetric key. An asymmetric key has two parts: one is a private key and the other is a public key. The private key is used to encrypt the data and the public key is used to decrypt the data.

TDE: is a full database level encryption that protects the data files and log files.
As per Microsoft documentation for TDE

SQL Server RPO and RTO

Recovery Point Objective(RPO) describes a point in time that data can be restored from. For instance, if there is data corruption, Data loss or unavailability, at what point in time can a valid copy of the data be restored from? RPO is usually measured as minutes, hours, days, weeks, etc… for Business Continuity.

If a database is corrupted then can we restore it back to what it was 15 minutes ago? This would be an RPO of 15 minutes for Business Continuity..

Recovery Time Objective (RTO) is the amount of time which data or hardware is desired to be restored after a data corruption or hardware failure.

If a Database server just died. Time needed to bring it up and … Read the rest
