AWS - S3 Encryption

Enterprise design
Project Overview
DSSE-KMS (Dual-Layered Server-Side Encryption with AWS Key Management Service) in Amazon S3 is an encryption method that provides double encryption for added security. With DSSE-KMS, data stored in S3 is encrypted using two independent layers of encryption, both managed by AWS KMS, each with a distinct encryption key.

Without DSSE, data stored in S3 has only a single layer of encryption, which could leave it more vulnerable if the encryption key is compromised. This may also impact industries with strict data security requirements—like finance, healthcare, or government—where dual-layered encryption is often necessary to ensure data integrity and mitigate risk. As a result, the absence of DSSE might make it difficult to meet specific regulatory obligations, potentially leading to compliance issues.


With DSSE, you can securely upload, copy, and replicate data in S3, ensuring that compliance requirements are consistently met without added complexity. This dual-layered encryption feature provides enhanced data protection, allowing you to manage sensitive information confidently and focus on your core operations. This update extends across nine features in S3, further strengthening security and compliance capabilities within the platform.
