What is required after creating a new compartment for users to gain access to it?

Creating a new compartment in Oracle Cloud Infrastructure (OCI) does not automatically provide access to any users or groups. To manage access effectively, it is necessary to define policies that explicitly grant permissions for users to operate within that compartment. This is governed by OCI's Identity and Access Management (IAM) system, which uses policies to control access to resources based on user roles.

In this context, writing a policy that grants access to the group associated with the users is vital. By doing so, you can ensure that all members of the group have the necessary permissions to interact with resources in the new compartment. This approach aligns with the principle of least privilege and makes management more efficient, as policies can be created at the group level rather than having to deal with individual permissions for every user.

This process highlights the need to actively manage permissions in OCI rather than relying on default settings or predefined policies, which might not exist for newly created compartments. Therefore, establishing an IAM policy that grants the appropriate access to the user group allows for controlled and secure access as intended within OCI's architecture.
