1. Introduction¶
AWS CodeCommit is a fully managed source control service that hosts secure and scalable private Git repositories. With the introduction of Customer Managed Key (CMK) support, AWS CodeCommit allows customers to have granular control over the encryption of their data at rest. This guide will walk you through the steps required to utilize the CMK support in AWS CodeCommit effectively.
2. Understanding Customer Managed Keys¶
Customer Managed Keys provide customers with complete control and ownership of their encryption keys. In the context of AWS CodeCommit, this means that customers can define and manage their own CMKs, allowing them to enforce fine-grained access controls and encryption policies. We will explore the various aspects of CMKs such as policy management, granting access, using tags, and creating aliases.
2.1 Policy Management¶
With CMK support in AWS CodeCommit, customers can define policies to control access to their keys. These policies enable customers to specify who can manage, use, and delete the CMKs, adding an extra layer of security to their CodeCommit repositories.
2.2 Grants and Access Control¶
One of the significant benefits of customer managed keys is the ability to grant granular access to different IAM users, groups, or roles. We will explain how to create grants and define access controls for CMKs to provide the right level of access to the relevant entities.
2.3 Tags and Aliases¶
Tags and aliases are essential aspects of managing CMKs as they provide a logical grouping mechanism and simplify key management. We will guide you through the process of creating tags and aliases for CMKs and demonstrate how they can be utilized effectively in CodeCommit.
3. Benefits of Customer Managed Keys¶
The support for CMKs in AWS CodeCommit offers several benefits to customers. We will explore these benefits in detail and highlight how they contribute to enhanced security, compliance, and fine-grained control over data encryption at rest.
3.1 Enhanced Security and Compliance¶
Customer Managed Keys provide an additional layer of security by allowing customers to manage their keys securely and vertically control their usage and access. We will discuss how CMKs strengthen the security posture of CodeCommit repositories and help customers meet their compliance requirements.
3.2 Fine-Grained Control¶
With CMK support, customers can enforce fine-grained access controls on CodeCommit repositories. This ensures that only authorized users and applications can access the repositories, further enhancing the security and privacy of the source code.
4. Managing CMKs with the AWS KMS Management Console¶
The AWS Key Management Service (KMS) Management Console allows customers to create, manage, and monitor their CMKs. In this section, we will provide a detailed walkthrough of the KMS Management Console, explaining how to create CMKs, manage key policies, create grants, and configure key rotation.
4.1 Creating Customer Managed Keys¶
We will guide you step-by-step on creating customer managed keys using the AWS KMS Management Console. This process involves specifying key metadata, defining key policies, and enabling key rotation for enhanced security.
4.2 Managing Key Policies¶
Key policies define who can manage, use, and delete the CMKs. We will explain the syntax and structure of key policies, and provide examples of common key policy configurations to help you get started.
4.3 Granting Access to CMKs¶
Creating grants is a critical aspect of CMK management, as it determines who can access and use the keys. We will walk you through the process of creating grants for different IAM entities and demonstrate how to enforce granular access controls for CMKs.
4.4 Configuring Key Rotation¶
Key rotation is an essential security practice that ensures keys are regularly updated to safeguard against vulnerabilities. We will discuss the benefits of key rotation and guide you through the process of configuring automatic key rotation for CMKs in the AWS KMS Management Console.
5. Defining Customer Managed Keys in CodeCommit¶
In this section, we will explore how to define customer managed keys for AWS CodeCommit repositories. We will provide detailed instructions on configuring repository-level encryption settings, associating CMKs with repositories, and enforcing encryption for data at rest.
5.1 Configuring Repository-Level Encryption Settings¶
We will explain the repository-level encryption settings available in CodeCommit and discuss how these settings can be utilized to enforce encryption requirements using customer managed keys.
5.2 Associating CMKs with Repositories¶
Learn how to associate CMKs with specific CodeCommit repositories and ensure that encryption is consistently enforced for all the data at rest in the repositories.
5.3 Enforcing Encryption for Data at Rest¶
We will demonstrate how to enforce encryption for data at rest in CodeCommit repositories by utilizing the CMKs defined earlier. This ensures that all data stored in CodeCommit is encrypted and provides an additional layer of security.
6. Utilizing Existing CMKs for CodeCommit¶
Customers who already have existing CMKs in use for other AWS services can now leverage them for AWS CodeCommit as well. In this section, we will guide you on how to integrate your existing CMKs with CodeCommit repositories.
6.1 Importing Existing CMKs to CodeCommit¶
We will discuss the steps required to import existing CMKs to CodeCommit and explain any additional configuration or considerations you should be aware of when utilizing these keys.
6.2 Best Practices for Utilizing Existing CMKs¶
We will share some best practices for leveraging existing CMKs in CodeCommit, including considerations for key rotation, updating key policies, and maintaining compliance while using pre-existing keys.
7. Best Practices for CMKs in AWS CodeCommit¶
