AWS S3 Encryption
AWS S3 Encryption is a security feature within Amazon Simple Storage Service (S3) that protects data at rest by encrypting objects stored in S3 buckets. It supports multiple encryption methods, including server-side encryption with keys managed by AWS (SSE-S3, SSE-KMS) or customer-provided keys (SSE-C), and client-side encryption where data is encrypted before upload. This ensures data confidentiality and compliance with security standards like GDPR or HIPAA.
Developers should use AWS S3 Encryption when storing sensitive data such as personal information, financial records, or intellectual property in S3 to prevent unauthorized access and meet regulatory requirements. It is essential for applications handling healthcare, e-commerce, or any scenario where data privacy is critical, as it mitigates risks from data breaches and simplifies compliance audits.
