What is the default Service Control Policy (SCP) that allows all actions in AWS Organizations?

The default Service Control Policy (SCP) that permits all actions in AWS Organizations is essentially designed to give wide-ranging access to the resources and actions available in the AWS environment. The reference to FullAWSAccess indicates a policy that includes permissions to allow all available actions without restrictions, which aligns with how AWS structures its SCPs to grant full functionality to accounts or organizational units under an organization.

In AWS Organizations, SCPs are crucial for managing permissions across accounts. The FullAWSAccess policy effectively serves as a comprehensive access policy, ensuring that no actions are denied unless explicitly restricted by another policy. This aids administrators in managing and ensuring that all necessary functionalities are accessible by default, fostering a streamlined operational environment for resource engagement and management.

By having policies like FullAWSAccess, organizations can confidently explore the capabilities of AWS services without the immediate constraint of permissions overhead, assuming that there are no other conflicting policies that would restrict access. Thus, selecting FullAWSAccess as the appropriate SCP reflects an understanding of the inherent flexibility AWS provides in managing permissions across multiple accounts.
