Amazon S3 now automatically encrypts all data using AES256.

Amazon Simple Storage Service will automatically encrypt any new objects that are added to buckets from the server, by default using AES256.

Although the server-side encryption system was available via AWS for the tech giant enabled it automatically to increase security.

The new encryption system will not affect administrators’ buckets. Amazon also promises that it won’t cause any performance issues.

“This change automatically puts another security best-practice into effect–with minimal impact on performance, and without any action required from your side,” reads .

S3 buckets which do not currently use default encryption will automatically set SSE-S3 to the default setting. S3 default encryption is not being used by existing buckets.

Administrators can choose to leave the system encrypted at the default level of 256 bits AES, or opt for one of the other methods, such as SSE C or SSE KMS.

SSE-C gives bucket owners the ability to manage the keys. SSE-KMS allows Amazon to do key management. To maintain greater control of the asset access system, bucket owners have the option to grant different permissions to each KMS key.

Administrators may to confirm the updates have been made to buckets. Next, perform a test object download and then look at the logs for “Default_SSE_S3”. The log will contain the file that was uploaded.

This will help you retroactively encode objects that are already stored in S3 buckets.

How to solve a major security issue

Security problems have plagued us for years. Poor practices and mistakes in configuration often expose the private details of millions.

There are two notable instances of Amazon S3 Storage Buckets data leakage: the December 2017 leak of data from and April 2019 leakage of by Facebook users.

The data would not have been as disastrous if it had been encrypted. However, because of overhead costs and operational complexity and the need to make performance sacrifices, encryption is often avoided.

Amazon’s decision to make server-side encryption “zero click” is an important step in improving security. It will also help to reduce the likelihood of data breaches that are bound to occur.

The encryption algorithms is considered to be the most powerful available. . It is also resistant to attacks.
