Default Encryption for new S3 Objects
Default Encryption for new S3 Objects

Amazon Web Services (AWS) recently announced a new feature for its Simple Storage Service (S3). This feature encrypts all new objects by default. S3 automatically applies server-side encryption (SSE-S3) for each new object. S3 buckets that do not use default encryption will use SSE-S3 as the default encryption option. Existing buckets currently using S3 default encryption will not change. You can always opt-in for different encryption options (SSE-KMS, SSE-C).
Before default encryption, users had to manually verify that encryption was enabled for the S3 bucket and make sure that it stayed that way. This could be time-consuming and prone to mistakes, as many security issues were related to S3 public access.
There are several benefits to using default encryption for S3. First and foremost, it ensures that all objects stored in an S3 bucket are encrypted, which is important for data security and compliance with regulatory standards such as the EU’s General Data Protection Regulation (GDPR) and the Payment Card Industry Data Security Standard (PCI DSS).
AWS offers several options for default encryption, including Amazon S3-Managed Keys (SSE-S3), AWS Key Management Service (SSE-KMS), and customer-provided keys (SSE-C). SSE-S3 uses keys managed by AWS to encrypt objects, while SSE-KMS allows users to manage their own keys and gives them the ability to audit and control access to their keys. SSE-C allows users to provide their own keys for encryption, which can be useful for organizations with strict key management policies.
Overall, the new default encryption feature for AWS S3 is a welcome addition that makes it easier for users to ensure the security of their data. It can save time and reduce the risk of mistakes, while also improving the security of data in transit and at rest.
