  • Understanding Azure Deny Assignments

Return to AZ-104 Tutorial

The purpose of a deny assignment is to attach a set of deny actions to a user, group, or service principal at a particular scope similar to a role assignment, for denying access. The Azure Deny assignments are used to prevent users from doing particular Azure resource operations, even if a role assignment permits them access.

Overview of Azure Deny Assignments

In Azure, “deny assignments” are a type of access control feature that allows you to restrict access to certain resources in your Azure environment. Deny assignments are used to prevent specific users or groups from accessing a particular resource or resource group, even if they have been granted permission to do so through other means, such as an allow assignment.

Deny assignments work by specifying a set of deny rules that apply to a particular resource or resource group. These rules can be based on a variety of criteria, including user or group membership, IP address, or other attributes. When a user or group attempts to access a resource that is covered by a deny rule, the access request is automatically denied, regardless of any other permissions they may have.

Deny assignments can be useful in a variety of scenarios, such as when you need to restrict access to sensitive data or resources, or when you want to enforce compliance with regulatory requirements or company policies. They can also be used in conjunction with allow assignments to create a more fine-grained access control strategy.

One important thing to keep in mind when working with deny assignments is that they can be complex to manage and troubleshoot, particularly when you are dealing with multiple rules or overlapping permissions. It is therefore important to carefully plan your access control strategy and regularly review your deny assignments to ensure that they are still meeting your needs.

Steps to Create Deny Assignments

Here are the steps to create deny assignments in Azure:

  • Identify the resource or resource group that you want to restrict access to.
  • Navigate to the Access Control (IAM) tab for that resource or resource group in the Azure portal.
  • Click the “Add” button to add a new role assignment.
  • Select the role that you want to assign. This can be a built-in Azure role or a custom role that you have created.
  • In the “Assign access to” section, select the user or group that you want to assign the role to. This can be a specific user or group, or you can use a service principal.
  • In the “Add a condition” section, click “Add” to add a new deny assignment.
  • Select the type of condition that you want to add. This can include things like IP address range, user or group membership, or specific tags.
  • Specify the details of the condition, such as the IP address range or the name of the user or group.
  • Click “Add” to add the deny assignment to the role assignment.
  • Review the details of the role assignment and click “Create” to save the changes.

Once you have created the deny assignment, it will take effect immediately and users or groups that match the conditions of the deny rule will be prevented from accessing the specified resource or resource group. You can modify or remove the deny assignment at any time by navigating to the Access Control (IAM) tab for the resource or resource group and editing the role assignment.

All Principals

All Principals is a system-defined principal introduced to support deny assignments. The All Principal represents all users, groups, service principals, and managed identities in an Azure AD directory. Therefore, if the principal ID is a zero GUID 00000000-0000-0000-0000-000000000000 and the principal type is SystemDefined, then the principal represents all principals. Note, we can combine All Principals with ExcludePrincipals to deny all principals except some users.

Limitation of All Principals –

  • Can be used only in Principals and cannot be used in ExcludePrincipals.
  • Principals[i].Type must be set to SystemDefined.

AZ-104 Exam Practice Questions

Question: You are a cloud administrator for a company and want to ensure that a specific group of users cannot create new resources in a specific resource group in Azure. Which Azure feature can you use to achieve this?

A) Azure Resource Locks

B) Azure Policy

C) Azure Role-Based Access Control (RBAC) with Deny Assignments

D) Azure Blueprint

Answer: C) Azure Role-Based Access Control (RBAC) with Deny Assignments. Deny Assignments allow you to block specific actions on a specific scope, such as a resource group, which is what is needed in this scenario.

Question: You have an Azure subscription that is used by multiple departments in your organization. You want to ensure that one particular department cannot deploy resources with a specific tag. Which Azure feature can you use to achieve this?

B) Azure Policy with Deny Assignments

C) Azure Role-Based Access Control (RBAC)

Answer: B) Azure Policy with Deny Assignments. Azure Policy allows you to define and enforce policies that can help you meet organizational or regulatory compliance goals. Deny Assignments can be used in conjunction with policies to prevent certain actions, such as deploying resources with a specific tag.

Question: You are a security analyst for a company and need to ensure that all virtual machines in your Azure environment are encrypted using Azure Disk Encryption. However, you want to make sure that the owner of a virtual machine can still access the disk if necessary. Which Azure feature can you use to achieve this?

D) Azure Deny Assignments

Answer: D) Azure Deny Assignments. Deny Assignments can be used to prevent unauthorized access to virtual machine disks while still allowing the owner to access them. By creating a Deny Assignment that denies the “Microsoft.Compute/virtualMachines/encrypt/action” action for everyone except the owner of the virtual machine, only the owner can encrypt or decrypt the virtual machine disk, but others are denied access.

Question: You are a cloud administrator for a company and need to ensure that certain users cannot access a particular Azure resource. Which Azure feature can you use to achieve this?

Answer: C) Azure Role-Based Access Control (RBAC) with Deny Assignments. Deny Assignments can be used in conjunction with RBAC to prevent certain users from accessing a particular Azure resource by denying the “Microsoft.Authorization/*/read” action for the group of users.

Question: You have a critical Azure resource that should never be deleted accidentally. Which Azure feature can you use to prevent deletion of this resource?

Answer: A) Azure Resource Locks. Resource Locks allow you to lock a resource to prevent accidental deletion or modification. By applying a lock to the critical Azure resource, it cannot be deleted accidentally, even by authorized users.

How to lock down a single confidential Resource Group in Azure

This is a short one, but something I couldn’t figure out without testing it first.

Let’s assume a scenario where a company has a single Azure subscription. They also then have a single Azure tenant (meaning, a single Azure AD). Within this Azure subscription, they’ve built services for years and now have more than 100 resource groups.

They’ve now built another service that requires 10 resource groups – for testing, production, QA, and all sorts of things. As this service is very different and will store confidential data, they have to lock down access to the service within the Azure subscription. Not even admins can peek at the databases or any of the services within the resource groups – unless granted access.

How do we configure this?

Let’s start by taking a look at one of those resource groups we need to lockdown. I have one resource group named azuresentinel , and it’s hosting my Azure Sentinel and relevant services for that. Checking under Access control (IAM) on Azure Portal, we can see the default permissions:

create deny assignment azure

A few inherited permissions from the Azure Subscription level. One from a Management Group and a few settings at the root level.

I want to remove the legacy Cloudyn account, which is no longer a useful service for me (the third from the bottom in the list). I select the Reader-level permissions and click on Remove in the top toolbar. Only to get this message:

create deny assignment azure

Because the permission is inherited (from the Azure subscription, we only have one), the inheritance cannot be broken at a lower level, like a Resource Group.

Let’s see on the Subscription level if I can tweak this permission higher up in the chain. By selecting the same account and access, I can remove it – at the subscription level:

create deny assignment azure

But this takes away ALL access for said account, everywhere! I only want to remove access for one Resource Group.

Going back to the Resource Group > IAM view, I see there is another tab called Deny assignments . Perhaps I can create a classic Deny setting within a Resource Group to remove access for specific accounts.

create deny assignment azure

The description implies this would work. But it also cleverly states “ at this time “, as if some sort of an update is impending for this feature. Thus, the only option is to create a new Azure Blueprint, and assign that to the Resource Group.

Seems awfully clumsy – I just want to remove permissions for 10 users, but not for 2 other users within one Resource Group. And creating a Blueprint just for this feels overkill.

Taking a look at creating a Blueprint, it clearly states that I need to select a lock assignment . The guidance, which is found here , then lists the lock levels: don’t lock, read only (for RG), read only (non-RG) and do not delete. None of these remove permissions – they just allocate locks, via assignments, that users don’t accidentally remove something important.

Back to the drawing board

So, it seems impossible to remove permissions for users who have inherited access from the Subscription level. Removing their permissions at the Subscription level would mean they lose all access – and re-adding that might be tricky and time-consuming, especially for admins.

We can, of course, audit access to our confidential and protected RGs. But even then, it would be time-consuming to monitor whether or not someone lists all the resources in an RG, either by accident or on purpose.

Using Azure Blueprints seems to be the preferred Microsoft approach, but it isn’t tackling the issue – it’s simply adding another method for protecting for accidental deletions mostly. It seems impossible to lock down a single Resource Group unless locking down a whole Subscription by removing all accessible for everyone (and granting those permissions later at resource levels).

The solution? Provision a new Azure Subscription, and move your confidential Resource Groups there. Lockdown access at the Subscription level.

I found a few feedback items ( here , here ) on this very same challenge from recent years. But no other fix than to deploy Blueprints for locks.

List Azure deny assignments

Similar to a role assignment, a deny assignment attaches a set of deny actions to a user, group, or service principal at a particular scope for the purpose of denying access. Deny assignments block users from performing specific Azure resource actions even if a role assignment grants them access.

This article describes how to list deny assignments.

You can't directly create your own deny assignments. Deny assignments are created and managed by Azure.

How deny assignments are created

Deny assignments are created and managed by Azure to protect resources. You can't directly create your own deny assignments. However, you can specify deny settings when creating a deployment stack, which creates a deny assignment that is owned by the deployment stack resources. Deployment stacks is currently in preview. For more information, see Protect managed resources against deletion .

Compare role assignments and deny assignments

Deny assignments follow a similar pattern as role assignments, but also have some differences.

Capability Role assignment Deny assignment
Grant access
Deny access
Can be directly created
Apply at a scope
Exclude principals
Prevent inheritance to child scopes
Apply to assignments

Deny assignment properties

A deny assignment has the following properties:

[!div class="mx-tableFixed"] Property Required Type Description DenyAssignmentName Yes String The display name of the deny assignment. Names must be unique for a given scope. Description No String The description of the deny assignment. Permissions.Actions At least one Actions or one DataActions String[] An array of strings that specify the control plane actions to which the deny assignment blocks access. Permissions.NotActions No String[] An array of strings that specify the control plane action to exclude from the deny assignment. Permissions.DataActions At least one Actions or one DataActions String[] An array of strings that specify the data plane actions to which the deny assignment blocks access. Permissions.NotDataActions No String[] An array of strings that specify the data plane actions to exclude from the deny assignment. Scope No String A string that specifies the scope that the deny assignment applies to. DoNotApplyToChildScopes No Boolean Specifies whether the deny assignment applies to child scopes. Default value is false. Principals[i].Id Yes String[] An array of Microsoft Entra principal object IDs (user, group, service principal, or managed identity) to which the deny assignment applies. Set to an empty GUID 00000000-0000-0000-0000-000000000000 to represent all principals. Principals[i].Type No String[] An array of object types represented by Principals[i].Id. Set to SystemDefined to represent all principals. ExcludePrincipals[i].Id No String[] An array of Microsoft Entra principal object IDs (user, group, service principal, or managed identity) to which the deny assignment does not apply. ExcludePrincipals[i].Type No String[] An array of object types represented by ExcludePrincipals[i].Id. IsSystemProtected No Boolean Specifies whether this deny assignment was created by Azure and cannot be edited or deleted. Currently, all deny assignments are system protected.

The All Principals principal

To support deny assignments, a system-defined principal named All Principals has been introduced. This principal represents all users, groups, service principals, and managed identities in a Microsoft Entra directory. If the principal ID is a zero GUID 00000000-0000-0000-0000-000000000000 and the principal type is SystemDefined , the principal represents all principals. In Azure PowerShell output, All Principals looks like the following:

All Principals can be combined with ExcludePrincipals to deny all principals except some users. All Principals has the following constraints:

  • Can be used only in Principals and cannot be used in ExcludePrincipals .
  • Principals[i].Type must be set to SystemDefined .

Deny Assignments ? or Resource Lock?

Hello! If I'm a global admin for all subscriptions in a tenant, what's the best way to quickly make a resource (virtual Machine) read only? eg. if I stop it, it remains stopped or it cannot be altered (unless someone is a global admin) so no deletions, etc...? Was thinking of resource lock but would the better way be a deny assignment? If so, what would I set it to if I want it to be a Role instead of a specific member/person?

Understand resource locking in Azure Blueprints

  • 4 contributors

On July 11, 2026, Blueprints (Preview) will be deprecated. Migrate your existing blueprint definitions and assignments to Template Specs and Deployment Stacks . Blueprint artifacts are to be converted to ARM JSON templates or Bicep files used to define deployment stacks. To learn how to author an artifact as an ARM resource, see:

  • Deployments

The creation of consistent environments at scale is only truly valuable if there's a mechanism to maintain that consistency. This article explains how resource locking works in Azure Blueprints. To see an example of resource locking and application of deny assignments , see the protecting new resources tutorial.

Resource locks deployed by Azure Blueprints are only applied to non-extension resources deployed by the blueprint assignment. Existing resources, such as those in resource groups that already exist, don't have locks added to them.

Locking modes and states

Locking Mode applies to the blueprint assignment and it has three options: Don't Lock , Read Only , or Do Not Delete . The locking mode is configured during artifact deployment during a blueprint assignment. A different locking mode can be set by updating the blueprint assignment. Locking modes, however, can't be changed outside of Azure Blueprints.

Resources created by artifacts in a blueprint assignment have four states: Not Locked , Read Only , Cannot Edit / Delete , or Cannot Delete . Each artifact type can be in the Not Locked state. The following table can be used to determine the state of a resource:

Mode Artifact Resource Type State Description
Don't Lock * Not Locked Resources aren't protected by Azure Blueprints. This state is also used for resources added to a or resource group artifact from outside a blueprint assignment.
Read Only Resource group Cannot Edit / Delete The resource group is read only and all its properties, except for tags, can't be modified. resources can be added, moved, changed, or deleted from this resource group.
Read Only Non-resource group Read Only Except for tags, the resource remains unalterable and cannot be deleted or modified.
Do Not Delete * Cannot Delete The resources can be altered, but can't be deleted. resources can be added, moved, changed, or deleted from this resource group.

Overriding locking states

It's typically possible for someone with appropriate Azure role-based access control (Azure RBAC) on the subscription, such as the 'Owner' role, to be allowed to alter or delete any resource. This access isn't the case when Azure Blueprints applies locking as part of a deployed assignment. If the assignment was set with the Read Only or Do Not Delete option, not even the subscription owner can perform the blocked action on the protected resource.

This security measure protects the consistency of the defined blueprint and the environment it was designed to create from accidental or programmatic deletion or alteration.

Assign at management group

The only option to prevent subscription owners from removing a blueprint assignment is to assign the blueprint to a management group. In this scenario, only Owners of the management group have the permissions needed to remove the blueprint assignment.

To assign the blueprint to a management group instead of a subscription, the REST API call changes to look like this:

The management group defined by {assignmentMG} must be either within the management group hierarchy or be the same management group where the blueprint definition is saved.

The request body of the blueprint assignment looks like this:

The key difference in this request body and one being assigned to a subscription is the properties.scope property. This required property must be set to the subscription that the blueprint assignment applies to. The subscription must be a direct child of the management group hierarchy where the blueprint assignment is stored.

A blueprint assigned to management group scope still operates as a subscription level blueprint assignment. The only difference is where the blueprint assignment is stored to prevent subscription owners from removing the assignment and associated locks.

Removing locking states

If it becomes necessary to modify or delete a resource protected by an assignment, there are two ways to do so.

  • Updating the blueprint assignment to a locking mode of Don't Lock
  • Delete the blueprint assignment

When the assignment is removed, the locks created by Azure Blueprints are removed. However, the resource is left behind and would need to be deleted through normal means.

How blueprint locks work

An Azure RBAC deny assignments deny action is applied to artifact resources during assignment of a blueprint if the assignment selected the Read Only or Do Not Delete option. The deny action is added by the managed identity of the blueprint assignment and can only be removed from the artifact resources by the same managed identity. This security measure enforces the locking mechanism and prevents removing the blueprint lock outside Azure Blueprints.

Screenshot of the Access control (I A M) page and the Deny assignments tab for a resource group.

The deny assignment properties of each mode are as follows:

Mode Permissions.Actions Permissions.NotActions Principals[i].Type ExcludePrincipals[i].Id DoNotApplyToChildScopes
Read Only

SystemDefined (Everyone) blueprint assignment and user-defined in Resource group - ; Resource -
Do Not Delete
SystemDefined (Everyone) blueprint assignment and user-defined in Resource group - ; Resource -

Azure Resource Manager caches role assignment details for up to 30 minutes. As a result, deny assignments deny action's on blueprint resources may not immediately be in full effect. During this period of time, it might be possible to delete a resource intended to be protected by blueprint locks.

Exclude a principal from a deny assignment

In some design or security scenarios, it may be necessary to exclude a principal from the deny assignment the blueprint assignment creates. This step is done in REST API by adding up to five values to the excludedPrincipals array in the locks property when creating the assignment . The following assignment definition is an example of a request body that includes excludedPrincipals :

Exclude an action from a deny assignment

Similar to excluding a principal on a deny assignment in a blueprint assignment, you can exclude specific Azure resource provider operations . Within the properties.locks block, in the same place that excludedPrincipals is, an excludedActions can be added:

While excludedPrincipals must be explicit, excludedActions entries can make use of * for wildcard matching of resource provider operations.

Deny Assignment in Azure Databricks - how do I get around this to access storage container?

The client """ has permission to perform action 'Microsoft.Storage/storageAccounts/listKeys/action' on scope '/my/storage/account'; however, the access is denied because of the deny assignment with name 'System deny assignment created by Azure Databricks .....'

What do I need to do to resolve this issue. I successfully loaded a file to the storage container but cannot access it from a python notebook. Here's the error from the notebook.

"shaded.databricks.org.apache.hadoop.fs.azure.AzureException: hadoop_azure_shaded.com.microsoft.azure.storage.StorageException: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature."

It appears the "Deny assignment" issue above is the cause? How can I resolve it. Appreciate your help.

I was expecting to be able to access file from a python notebook with "%fs ls /mnt/...." but the command failed.
