Implementing appropriate access control is a fundamental component in securing your Azure environment. One way to achieve this is through the use of Azure’s delegated access feature. This article will guide you through the process and understanding of configuring delegated access, especially pertaining to the Azure Security Technologies, AZ-500 exam.
Azure delegated access allows administrators to grant specific permissions to users, groups, and applications, providing them the authority to perform specific tasks within a particular scope. This practice bolsters security protocols and ensures that your organization remains within compliance.
Steps for achieving Delegated Access Control
Here is a representative overview of the step-by-step process:
1. Establish a Role:
A “role” is essentially a set of permissions that dictate what actions a user or application can perform. Azure provides several built-in roles that you can assign, like “Contributor,” “Reader,” or “User Access Administrator.” However, you can create custom roles if your organization has unique needs.
Azure uses the Role-Based Access Control (RBAC) model, where permissions are grouped into roles, and these roles can then be assigned to users, groups, service principals, or managed identities.
Basic steps to create a custom role:
- In the Azure portal, browse to Azure Active Directory > Roles and administrators > New custom role.
- Provide a name and description for the custom role.
- Select the permissions to assign to the role and click “Next.”
- Review and then click “Create.”
2. Delegating Access:
Once you have defined roles, you can proceed to assign these roles to users, groups, or applications. You can do this on a subscription, resource group, or individual resource basis.
Steps to delegate access:
- In the Azure portal, navigate to the scope where you wish to assign the role (e.g., a subscription, resource group, or resource).
- Select “Access control (IAM)” > “Add role assignment.”
- Choose the role you want to assign from the “Role” dropdown.
- From the “Assign access to” dropdown, choose “User, group, or service principal.”
- In the “Select” box, search for the user, group, or service principal you want to assign the role to. Click on the name, then click “Save.”
Please note: Azure Active Directory (Azure AD) premium P1 or P2 is required for group-based assignment.
3. Monitor and Govern Delegated Access:
After roles and role assignments are in place, it is crucial to periodically review and modify these assignments as per the needs of your organization.
In the Azure portal, you can view the effective permissions of a user by choosing “Access control (IAM)” > “Check access.” Here, you can select a user, group, or service principal to find which roles they’ve been assigned at that scope.
Conclusion
In conclusion, understanding and effectively implementing delegated access is a crucial aspect of securing your Azure environment. Studying and practicing these steps will prepare you for questions in the AZ-500 Microsoft Azure Security Technologies exam, enabling you to achieve a high score and obtain a thorough comprehension of Azure security management.
