1. What is AWS Directory Service?

Overview of AWS Directory Service

AWS Directory Service is a managed service that allows you to connect your AWS resources with an existing on-premises Active Directory or to create a new, standalone directory. It offers multiple directory types, including AWS Managed Microsoft AD, AD Connector, and Simple AD.

AWS Managed Microsoft AD enables you to use Active Directory features such as user and group management, domain join, and Group Policy. AD Connector, on the other hand, allows you to connect your self-managed Active Directory to AWS without the need to replicate directory data. Simple AD is a directory service based on Samba, offering compatibility with Microsoft Active Directory tools.

Key features and benefits

  • Seamless integration with existing on-premises infrastructure.
  • Reduces the complexity of managing Active Directory services.
  • Provides high availability, scalability, and fault tolerance.
  • Supports common Active Directory features like single sign-on (SSO) and Group Policies.
  • Simplified administration through the AWS Management Console.

2. What is AWS Private CA?

Understanding AWS Private CA

AWS Private CA, also known as AWS Certificate Manager (ACM) Private Certificate Authority, allows you to create and manage a private certificate authority (CA) that issues and revokes certificates. It offers a scalable and highly available solution for issuing certificates within your organization, eliminating the need for third-party CAs.

With AWS Private CA, you maintain full control over the CA hierarchy, certificate lifecycle, and key management. This ensures the security and integrity of your certificates, enabling you to meet compliance requirements and protect sensitive data.

Use cases for AWS Private CA

  • Secure Web Applications: Use AWS Private CA to issue SSL/TLS certificates for secure communication between clients and your web applications.
  • Secure IoT Communication: Utilize AWS Private CA to issue certificates for IoT devices, ensuring secure and authenticated communication.
  • Internal Application Authentication: Use Private CA certificates to authenticate internal applications and services within your organization.
  • Code Signing: Generate code signing certificates with AWS Private CA to ensure the authenticity and integrity of your software releases.
  • Secure Email Communication: Employ AWS Private CA to issue S/MIME certificates for encrypting and digitally signing email messages.

3. Setting up AWS Private CA Connector for AD

Configuring AWS Managed Microsoft AD

To set up AWS Private CA integration with AWS Managed Microsoft AD, you first need to configure and provision your managed AD directory. Follow these steps to get started:

  1. Create a new AWS Managed Microsoft AD directory or choose an existing one.
  2. Configure the directory details such as domain name, VPC settings, and directory size.
  3. Select the desired edition (Standard or Enterprise) based on your requirements.
  4. Specify the administrative credentials and directory prefix.
  5. Confirm the settings and create the directory.

Connecting AWS Private CA to AWS Managed Microsoft AD

Now that you have your AWS Managed Microsoft AD directory in place, it’s time to connect AWS Private CA to it. This connection allows AWS Private CA to issue and manage certificates for your directory objects, such as users, groups, and machines. Follow these steps to complete the integration:

  1. In the AWS Management Console, navigate to the AWS Private CA service.
  2. Create a new Private CA, specifying the desired configuration options and CA hierarchy.
  3. Select the AWS Managed Microsoft AD directory as the certificate authority.
  4. Configure the certificate revocation settings and key algorithms.
  5. Configure the certificate subject properties based on your organization’s requirements.
  6. Review the settings and create the Private CA.

4. Setting up AWS Private CA Connector for AD Connector

Managing your self-managed AD environment with AD Connector

If you have a self-managed AD environment and wish to leverage the capabilities of AWS Private CA, you can do so by using AD Connector. AD Connector enables you to connect your self-managed AD to AWS without the need to replicate directory data.

AD Connector provides the benefits of seamless integration with other AWS services while ensuring your directory data remains on-premises. This allows you to maintain control over your AD environment while utilizing the certificate management features of AWS Private CA.

Configuring AWS Private CA for AD Connector integration

To set up AWS Private CA integration with AD Connector, follow these steps:

  1. Install and configure AD Connector in your on-premises environment.
  2. Establish a network connection between your self-managed AD and your AWS VPC.
  3. Create a new AWS Private CA and select AD Connector as the certificate authority.
  4. Configure the certificate revocation settings and specify the key algorithm.
  5. Define the certificate subject properties, including SANs and restrictions.
  6. Review the configuration settings and create the Private CA.

Best practices for integration

  • Ensure that your AD Connector and self-managed AD are operating on the latest versions and security patches.
  • Establish secure network connectivity between your on-premises environment and AWS, using VPN or Direct Connect.
  • Regularly monitor the health and performance of your AD Connector to ensure seamless integration.
  • Implement a robust certificate lifecycle management strategy, including regular certificate rotation, renewal, and revocation.
