Test case for RBAC

Question

My admin team has created roles and permissions to be assigned to users of different functional groups by using RBAC in Azure. My task is to create test cases to ensure that the assigned roles and permissions are in accordance with what has been agreed. I am relatively new to Azure and not sure on how to produce these test cases for the multiple roles. It would be great to have some recommendations on tools that I can start off with or some documentations for me to refer to. Thanks in advance.

Answer 1

I would start by looking at Resource Groups for testing the assignments and effects in. You can create a Service Principal in Azure Active Directory to be your "test user", which is then granted increasing role assignments.

You'll need to orchestrate two scripts (bash/powershell)

1. Authenticated as a Resource Group owner, which will be responsible for adding/removing roles for your test user
2. Authenticated as your test user, which will try to perform a series of operations.

When creating test cases for Azure Role-Based Access Control (RBAC) role assignments, you should consider various scenarios to ensure proper testing coverage. Here are some steps you can follow to create test cases for Azure RBAC role assignments:

Identify the role assignments: Start by identifying the specific role assignments you want to test. Understand the roles involved, the resources they apply to, and the expected permissions and access levels.

Define test objectives: Determine the objectives of your test cases. For example, you might want to verify that role assignments are correctly applied, that users have the expected level of access, or that specific permission scenarios are handled correctly.

Create test scenarios: Based on the identified role assignments and objectives, create various test scenarios that cover different aspects of RBAC role assignments. Consider the following scenarios:

a. Positive scenarios: Test cases where the role assignments are expected to work correctly, and users have the appropriate access and permissions.

b. Negative scenarios: Test cases where the role assignments should not grant access or permissions. This includes scenarios where users are not assigned any roles or are assigned incorrect or unauthorized roles.

c. Edge cases: Test cases that cover special conditions, such as testing maximum role assignments, testing combinations of roles, or scenarios where users have overlapping role assignments.

d. Error scenarios: Test cases that check how the RBAC system handles errors, such as assigning roles to non-existent users or resources, or exceeding RBAC limits.

Design test data: Prepare the necessary test data for your scenarios. This includes creating users, resources, and defining the role assignments you want to test. You can use Azure Portal, Azure CLI, Azure PowerShell, or Azure Resource Manager templates to create and manage these test resources.

Execute test cases: Execute each test case by performing the necessary actions to validate the RBAC role assignments. This may involve assigning and removing roles, checking access levels, verifying permissions, and observing the expected behavior.

Validate results: Compare the actual results against the expected outcomes defined in your test objectives. Determine whether the RBAC role assignments function as intended and whether users have the correct access and permissions.

Document and report: Document the test cases, test results, and any issues encountered during testing. Provide a clear and concise report summarizing the test coverage, test results, and any identified issues or improvements.

By following these steps, you can create comprehensive test cases for Azure RBAC role assignments, ensuring the proper functioning of access control and permissions within your Azure environment.

Hi Alfi,

One good approach is using the Check Access tool from Access Control (IAM).

You have the IAM and the Check Access available on each resource.

You can follow the steps on the following link: https://learn.microsoft.com/en-us/azure/role-based-access-control/check-access

Another good approach is to check the role assignments with scripts. In this case, you must create a Powershell script or use other options such as Azure CLI and REST API. Based on that, your script can receive arguments to validate the assignments for a specific user, subscription, resource, or resource group. With this Script, you're able to validate it using an automated approach.
