Oracle Cloud OCI Identity and Access Management (IAM) Security

Oracle Cloud OCI Identity and Access Management(IAM) Security

This blog refers to the Oracle Cloud Infrastructure (OCI) console to implement users, groups, policies, and other components basic security needs. For large organizations or data center Oracle suggests that the security be addressed and maintained by a Security Analyst or Solutions Architect role. As you will soon see as you explore OCI that there are many ways to add and manage components. See Documentation to Use for Cloud Identity for detailed information from Oracle.

Order of Component Creation

Compartments, users, groups, and policies can be created in a variety of orders. However, the security components do depend on each other. For instance, all users, groups, and policies must be created in a compartment. Therefore, if the compartment does not exist then it must be created. When you create other components, you must select a compartment. Do this by clicking on compartment dropdown located mid-way down on the left side of the page and then clicking the compartment name from the list. Once the compartment exists, then a group needs to be created, unless it already exists. Policies are dependent on a compartment and a group. Once the group exists, then a new policy may need to be created, unless it already exists and attach the policy to corresponding group. Lastly, a user is dependent on a compartment and must be assigned to a group with an attached policy.

Permission Level

The permission level is specified by the verb in the statement. To give another user access to interact with your environments in the Oracle Cloud Console, use one of the following verbs in your policy statements:

• manage – allows the user to perform all management tasks for an environment, including create and delete (when supported).
• use – allows the user to update an existing environment; user can’t create or delete an environment.
• read – allows the user to view all information about the environment.
• inspect – allows the user to list the environments only; user can’t view the details pages.

For more information on the operations permitted by each of these verbs, see Policy Syntax.
