AWS CodeCommit supports file-level encryption through AWS Key Management Service (KMS). When creating a repository, you can choose to enable encryption by selecting a KMS key. This ensures that all files and metadata within the repository are encrypted at rest using the specified key.
File-level encryption is crucial for maintaining data security and compliance. It protects sensitive information from unauthorized access, even if an attacker gains access to the underlying storage infrastructure. Additionally, it helps organizations meet regulatory requirements such as GDPR, HIPAA, and PCI DSS by safeguarding confidential data.
