2. Understanding AWS Control Tower’s Account Factory for Terraform

AWS Control Tower’s Account Factory for Terraform (AFT) is a service provided by AWS that allows organizations to programmatically create and manage AWS accounts at scale. AFT leverages the power of Terraform, an open-source infrastructure as code software tool, to automate the account creation and management process.

By using AFT, organizations can achieve consistent and standardized account creation, provisioning, and configuration across their AWS environment. AFT allows you to define reusable templates and apply them to create AWS accounts with preconfigured resources such as VPCs, security groups, IAM roles, and more.

3. Customizing AFT Resources

One of the key features of AFT is the ability to customize the resources that are deployed and recorded by AFT. This allows organizations to tailor their AWS accounts to meet their specific requirements and preferences.

3.1 Customizing VPC Configuration

With AFT, you have the option to choose whether or not to deploy using a VPC. By default, AFT creates a VPC for each account, providing a network isolation boundary for resources within that account. However, in some cases, you may want to deploy AFT without a VPC, especially if you already have an existing VPC setup that you want to use.

To customize the VPC configuration for AFT, you can modify the Terraform templates provided by AWS. This allows you to define your own VPC settings, such as IP ranges, subnets, route tables, and security groups. By customizing the VPC configuration, you can align the AFT deployment with your organization’s networking strategy and security requirements.

3.2 Customizing Resource Retention Periods

AFT also allows you to customize the retention periods for AWS Backup recovery points, Amazon CloudWatch log groups, and Amazon S3 log archive buckets. These retention periods define how long the data will be retained in these services before it is automatically deleted.

By default, AFT sets the retention periods to a predefined value. However, different organizations may have different regulatory or compliance requirements that demand longer or shorter retention periods. With AFT, you can easily modify these retention periods to meet your organization’s unique data retention needs.

4. Deployment with Virtual Private Cloud (VPC)

AFT provides seamless integration with AWS VPC, allowing you to deploy new accounts within a VPC infrastructure. This integration enables organizations to maintain a consistent networking strategy and security posture across their AWS environment.

When deploying AFT with VPC, you can take advantage of the following benefits:

  1. Network isolation: Each account created by AFT will be provisioned with its own VPC, allowing for complete network isolation from other accounts and resources within the organization.
  2. Traffic control: With VPC, you can define network access control lists (ACLs) and security group rules to control inbound and outbound traffic to your accounts, ensuring that only authorized communication is allowed.
  3. Enhanced security: By deploying AFT within a VPC, you can leverage AWS security features such as VPC flow logs, VPC peering, and AWS Network Firewall to enhance the security of your organization’s AWS environment.

5. Retention Period Customization

AFT allows you to customize the retention periods for various AWS services, including AWS Backup, Amazon CloudWatch, and Amazon S3. Customizing these retention periods enables organizations to comply with regulatory requirements, meet data retention policies, and optimize storage costs.

5.1 Customizing AWS Backup Retention Periods

With AFT, you can modify the retention periods for AWS Backup recovery points. AWS Backup is a fully managed backup service that simplifies the process of backing up and restoring your AWS resources, such as Amazon EBS volumes, Amazon RDS databases, and Amazon DynamoDB tables.

By default, AFT sets the retention period for AWS Backup recovery points to a predefined value. However, your organization may have specific backup and recovery requirements that demand longer or shorter retention periods. By customizing the retention periods, you can ensure that your backup data is retained for the desired duration.

5.2 Customizing Amazon CloudWatch Log Retention Periods

Amazon CloudWatch is a monitoring and observability service provided by AWS. It allows organizations to collect and analyze log files, set alarms, visualize metrics, and gain insights into the performance and health of their applications and infrastructure.

AFT allows you to customize the retention periods for Amazon CloudWatch log groups. By default, AFT sets the retention period to a predefined value. However, depending on your organization’s compliance and auditing requirements, you may need to retain log data for a longer duration. By customizing the retention periods, you can ensure that your log data is retained for the desired duration.

5.3 Customizing Amazon S3 Log Archive Bucket Retention Periods

AFT also provides the ability to customize the retention periods for Amazon S3 log archive buckets. Amazon S3 is a highly scalable and durable object storage service offered by AWS. It allows organizations to store and retrieve any amount of data from anywhere on the web.

AFT automatically creates an S3 log archive bucket for each AWS account. This bucket is used to store log files generated by various AWS services, such as CloudTrail, AWS Config, and AWS Firewall Manager. By default, AFT sets the retention period for the log archive bucket to a predefined value. However, you can customize this retention period to meet your organization’s specific requirements.

6. Enhancements to AFT VPC Default Security Group

AFT VPC default security group is a preconfigured security group that is automatically created for each AWS account provisioned by AFT. This security group controls inbound and outbound traffic to resources within the account.

The recent release of AFT includes enhancements to the default security group to align with AWS Foundational Security Best Practices. These enhancements further strengthen the security posture of your AWS environment and help prevent unauthorized access and data breaches.

The key enhancements to the AFT VPC default security group include:

  1. Restricting inbound and outbound traffic: The default security group now has stricter inbound and outbound rules to ensure that only necessary traffic is allowed.
  2. Defending against common network-based attacks: The default security group now includes rules to block common network-based attacks, such as port scanning, denial-of-service (DoS) attacks, and IP spoofing.
  3. Simplified management: The default security group is automatically managed by AFT, reducing the administrative burden of managing security group rules manually.
