AWS Organization

AWS Organizations provides centralized management for multiple AWS accounts, enabling policy enforcement, account structure organization, and security best practices across an enterprise.

Why SecureCart Uses AWS Organizations & OUs for Multi-Account Security

• Centralized management of multiple AWS accounts.

• Granular access control using Service Control Policies (SCPs).

• Secure authentication & authorization with IAM Identity Center (AWS SSO).

• Isolation of workloads with Organizational Units (OUs).

• Cost and billing optimization via consolidated billing.

AWS Organizations and OUs Overview

AWS Organizations

AWS Organizations is a service that allows SecureCart to

• Manage multiple AWS accounts centrally.

• Define access policies (SCPs) across accounts.

• Use Organizational Units (OUs) to group accounts logically.

• Enable IAM Identity Center (AWS SSO) for federated access across accounts.

Organizational Units (OUs)

• OUs help SecureCart organize AWS accounts into hierarchical groups.

• Policies (SCPs) are applied at the OU level to enforce security best practices.
