[Instructor] Database encryption is an extremely important aspect of database security. Let's understand the concepts of why encryption is important and what type of encryption exists in the Oracle database. There are two major types of encryption that are relevant to us. The first one is called data-at-rest encryption and the second one is called network encryption. Let's start by explaining the first: data-at-rest encryption and how it relates to the Oracle database. All of your database data is stored on disk. Disk could be a local disk, physically installed inside the database server itself, or an enterprise-grade storage machine to which the Oracle database is connected via fiber channel or ethernet network. Without encryption, your data, stored on that disk or disks in plural, is written in visible format. This means that if someone gets a hold of the disks storing your database data, they will get access to the actual data itself from your database tables. So it's a major…
