# Data protection in AWS CodeCommit
<a name="data-protection"></a>

As a managed service, is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see [AWS Cloud Security](https://aws.amazon.com/security/). To design your AWS environment using the best practices for infrastructure security, see [Infrastructure Protection](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/infrastructure-protection.html) in *Security Pillar AWS Well‐Architected Framework*.

You use AWS published API calls to access through the network. Clients must support the following:
+ Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.
+ Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.

CodeCommit repositories are automatically encrypted at rest. No customer action is required. CodeCommit also encrypts repository data in transit. You can use either the HTTPS protocol, the SSH protocol, or both with CodeCommit repositories. For more information, see [Setting up for AWS CodeCommit](setting-up.md). You can also configure [cross-account access](cross-account.md) to CodeCommit repositories.
