What is the recommended approach for defining security for an upcoming proof of concept (POC) when existing resources are in the root compartment?

Creating a new compartment for the proof of concept (POC) and granting appropriate permissions is the recommended approach for defining security, particularly when dealing with existing resources in the root compartment. This approach allows for better management and isolation of resources dedicated to the POC, ensuring that the POC operates independently from other resources within the root compartment.

Using a separate compartment provides a clear boundary for resource access and management. It is easier to implement granular access control with specific policies that pertain only to the resources utilized in the POC. This setup reduces the risk of accidental access or modifications to essential resources that exist in the root compartment, thereby enhancing the overall security posture.

Additionally, by granting appropriate permissions tailored to the requirements of the POC, you can ensure that the right individuals have the level of access they need without over-permissioning, which could expose resources to potential security risks.

In contrast, creating a new tenancy complicates the setup and management process; it might require unnecessary overhead and complexity for a single POC. Provisioning resources directly into the root compartment with limited permissions offers minimal isolation and security enhancements. Lastly, using defined tags for separation does not provide the same level of access control and compartmentalization as creating a new compartment, leading to
