Question

Difficulty: MediumMulti-Account Governance and Organizational Structure

A solutions architect is establishing a multi-account governance structure using AWS Organizations. The security architecture requires that corporate permission guardrails are active and applied to all member accounts immediately upon their inclusion in the organization, preventing any temporary window of non-compliance. What is the correct sequence of steps to configure this organizational structure?

  1. 1Enable AWS Organizations from the designated management account with all features enabled.
  2. 2Design and create the Organizational Unit (OU) hierarchy to align with the enterprise's governance needs.
  3. 3Author the Service Control Policies (SCPs) in the management account to define maximum allowable permissions.
  4. 4Attach the Service Control Policies (SCPs) to the appropriate target Organizational Units (OUs).
  5. 5Provision new member accounts or invite existing accounts, placing them directly into the configured Organizational Units (OUs).

Answer

The correct sequence is to first enable AWS Organizations, design and create the Organizational Unit hierarchy, author the Service Control Policies, attach these policies to the target Organizational Units, and finally provision or move member accounts into their respective Organizational Units.
The correct order establishes the management boundary (AWS Organizations), creates the logical containment structure (OUs), authors the policy guardrails (SCPs), applies the policies to the containers (OUs), and finally populates the containers with member accounts. This workflow ensures that no account exists in an OU without the governance policy already active and inherited, eliminating any window of vulnerability.

Step-by-Step Solution

1
Enable AWS Organizations.
The multi-account organization is initialized and the management account is established.
An organization must exist to act as the boundary for OUs, accounts, and policies.
2
Create Organizational Units (OUs).
Logical grouping containers are established within the organization.
OUs act as the logical target for policy application and account segregation.
3
Author Service Control Policies (SCPs).
SCPs are saved as policy documents in the management account.
SCPs must be defined in the organization before they can be attached to containers.
4
Attach SCPs to OUs.
Guardrails are active on the OUs.
Attaching SCPs to OUs before moving accounts ensures that security guardrails are applied immediately on account entry, avoiding any security gaps.
5
Move or provision accounts into OUs.
Accounts are active and governed by the inherited SCPs.
Member accounts inherit the policies attached to their parent OUs instantly, ensuring compliance from day one.

Key Concept

Enforcing immediate policy inheritance in AWS Organizations by attaching Service Control Policies (SCPs) to Organizational Units (OUs) prior to moving or provisioning member accounts.
