Protecting data on Amazon S3

In this section, you will learn how to record every version of an object. Along with durability, Amazon provides several techniques to secure the data in S3. Some of those techniques involve enabling versioning and encrypting the objects.

Versioning helps you to roll back to a previous version if any problem occurs with the current object during update, delete, or put operations.

Through encryption, you can control the access of an object. You need the appropriate key to read and write an object. You will also learn Multi-Factor Authentication (MFA) for delete operations. Amazon also allows Cross-Region Replication (CRR) to maintain a copy of an object in another Region, which can be used for data backup during any disaster, for further redundancy, or for the enhancement of data access speed in different Regions.
