How to Secure AWS S3 Data with Encryption At Rest

AWS S3 provides multiple tools for securing data with things like access control lists and policy restrictions. Another one of the mechanisms AWS offers to secure data is the ability to encrypt data before sending it to S3. Encrypting data before storing it in S3 is easy, too.

The AWS SDK offers encryption out of the box. Developers don't need to use other encryption methods to secure data before transporting it to S3. Instead, they can use the AWS SDK to encrypt data with either AES or RSA encryption schemes. This allows a way for developers to access native encryption functions without risking using libraries maintained by developers with whom they don't know.

To use AWS encryption functions, developers will need to create master keys, or private keys, stored with AWS's Key Management System. KMS is a service provided by AWS to secure and manage private API and encryption keys. It works similarly to IAM and can also be controlled through IAM policies as well.

For more information and examples on how to use encryption methods through the AWS SDK, visit the AWS knowledge base article titled Protecting data using client-side encryption.
