  7. 7. Service Overview
  8. 8. AWS Organizations • New management capability for centrally managing multiple AWS accounts - Simplified creation of new AWS accounts - Logically group AWS accounts for management convenience - Apply organizational control policies (OCP) - Simplified billing • Console, SDK, and CLI support for all management tasks
  9. 9. AWS Organizations A1 A2 A4 M Master Account / Administrative root Organizational Unit (OU) AWS Account Organization Control policy (OCP) AWS Resources A3 Dev Test Prod
  10. 10. Apply Organizational Control Policies (OCP) • Describes controls to be applied • Different use cases have different types of OCPs • OCPs can be attached to - Organization - OUs - AWS account • OCPs are inherited up the hierarchy - AWS Account OU Organization
  11. 11. AWS Organizations A1 A2 A4 A Dev Test Prod A3
  12. 12. OCP V1: Service Control Policies (SCPs) • Enables you to control which AWS service APIs are accessible - Define the list of APIs that are allowed – Whitelisting - Define the list of APIs that must be blocked – Blacklisting • Cannot be overridden by local administrator • Resultant permission on IAM user/role is the intersection between the SCP and assigned IAM permissions • Necessary but not sufficient • IAM policy simulator is SCP aware
  13. 13. SCPs are necessary but not sufficient SCP IAM Allow: S3:* Allow: SQS:* Allow: EC2:*Allow: EC2:*
  14. 14. Simplified Billing • Single payer for all AWS accounts • All AWS usage across AWS accounts in your organization rolled up for volume pricing and billing • All existing Consolidated Billing families will be migrated to an organization in billing mode
  15. 15. Different Management Levels You select the management level when creating a new organization Billing mode • Backward-compatible with current Consolidated Billing (CB) • Organization created from Consolidated Billing family automatically in Billing mode Full-control mode • Everything included in Billing mode • Enables management of ALL types of OCPs • Changing from Billing mode to Full control mode requires consent from all AWS accounts in your organization
  16. 16. Least Privilege for Management • IAM permissions for all AWS Organizations actions • You can also specify AWS Organizations resources (organization, OU, AWS account) as resources in an IAM policy • You can delegate permissions to manage your organization to an IAM user in another AWS account by using IAM roles • All organization management activity is logged in AWS CloudTrail
  17. 17. Best practices
  18. 18. Best practices – AWS Organizations • Monitor activity of the master account using CloudTrail • Do not manage resources in the master account • Manage your organization using the principle of “Least Privilege” • Use OUs to assign controls • Test controls on single AWS account first • Only assign controls to root of organization if necessary • Avoid mixing “whitelisting” and “blacklisting” SCPs in organization • Create new AWS accounts for the right reasons
  19. 19. • Reduce or remove use of root • Create Individual IAM Users • Configure a strong password policy • Enable MFA for privileged users • Grant least privilege • Manage permissions with groups • Restrict privileged access further with conditions • Rotate security credentials regularly • Use IAM roles to share access • Use IAM roles for Amazon EC2 instances • Monitor activity Best practices – AWS IAM
  20. 20. • AWS Organizations • IAM Policies for AWS Organizations • Logging AWS Organizations events with AWS Cloudtrail • Troubleshooting AWS Organization Policies • IAM Policy Simulator Resources
