Pipeline: 2.24 Ensure a Custom Role is Assigned Permissions for Administering Resource Locks

Description

Resource locking is a powerful protection mechanism that can prevent inadvertent modification/deletion of resources within Azure subscriptions/Resource Groups and is a recommended NIST configuration.

Given the resource lock functionality is outside of standard Role Based Access Control(RBAC), it would be prudent to create a resource lock administrator role to prevent inadvertent unlocking of resources.

Remediation

From Azure Portal

  1. In the Azure portal, open a subscription or resource group where you want the custom role to be assigned.
  2. Select Access control (IAM).
  3. Click Add.
  4. Select Add custom role.
  5. In the Custom role name field enter Resource Lock Administrator.
  6. In the Description field enter Can Administer Resource Locks.
  7. For Baseline permissions select Start from scratch.
  8. Select Next.
  9. In the Permissions tab select Add permissions.
  10. In the Search for a permission box, type in Microsoft.Authorization/locks to search for permissions.
  11. Click on the result.
  12. Check the box next to Permission.
  13. Select Add.
  14. Select Review + create.
  15. Select Create.
  16. Assign the newly created role to the appropriate user.

From PowerShell:

Below is a power shell definition for a resource lock administrator role created at an Azure Management group level

Import-Module Az.Accounts
Connect-AzAccount
$role = Get-AzRoleDefinition "User Access Administrator"
$role.Id = $null
$role.Name = "Resource Lock Administrator"
$role.Description = "Can Administer Resource Locks"
$role.Actions.Clear()
$role.Actions.Add("Microsoft.Authorization/locks/*")
$role.AssignableScopes.Clear()
* Scope at the Management group level Management group
