Data protection in key AWS services

In this section, we will delve into the various mechanisms and strategies for data protection across key AWS services, showing how encryption and key management are just pieces of a larger puzzle that also includes backups and access control.

S3 buckets

While S3’s ease of use and scalability make it popular, securing data stored in buckets is essential. Let’s dive into data protection features in S3, focusing on versioning, encryption, and access control.

When versioning is enabled on an S3 bucket, any overwrite or delete operation on an object doesn’t remove the previous versions. This allows for easy recovery and provides an additional layer of security.

For those who are already quite familiar with S3 versioning, you might be aware that...
