AWS AmazonS3 documentation change
Summary
Clarified DSSE-KMS documentation by removing redundant cost explanations, adding pricing links, and reformatting comparison bullets (italic to bold). Enhanced emphasis on dual-layer encryption security benefits.
Security assessment
The changes focus on improving documentation structure and emphasizing existing security benefits of DSSE-KMS (dual-layer encryption). No evidence of addressing a specific vulnerability or incident. Updates reinforce security feature documentation but don't disclose new vulnerabilities or fixes.
