AWS CodeCommit公式のofficial product user guide / documentation page ('What is AWS CodeCommit?' overview)(https://docs.aws.amazon.com/codecommit/latest/userguide/welcome.html)は、AWS CodeCommitのセキュリティ体制に関する一次情報である。The existing References focus almost entirely on the onboarding-pause/reopening timeline and AWS-ecosystem integration; none mention CodeCommit's data-protection/encryption posture, which is a genuinely new and commonly relevant security-architecture fact.具体的には「AWS CodeCommit repositories are encrypted both at rest and in transit, as stated in AWS's own official documentation for the service.」といった記載がある。ただし、認証・準拠・体制の状況は更新されうるため、この内容は取得時点のものです。適用範囲がどこまでかは、このSourceだけでは確認できない場合があります。 The documentation states encryption at rest and in transit as a general fact but does not specify the exact encryption algorithm, key management scheme (e.g. whether AWS-managed KMS keys or customer-managed keys are used by default), or key rotation details on this particular page; those specifics would require checking a dedicated security/encryption reference page.2026年08月23日に同Sourceを取得し、この内容を確認した。検証待ちAWS CodeCommitセキュリティ体制に関する公開情報
