OCI IAM policies control who can access which resources, how, and under what conditions. All resources have an implicit deny by default — access must be explicitly granted via policy statements. Policies are collections of one or more statements written in a human-readable language.
Permissions are the atomic units of authorization in OCI IAM. Instead of using a verb like use or manage, you can list exact permissions inside {} for surgical least-privilege access.
