A Beginner's Guide To Role-Based Access Control on Azure.
When creating access to systems, applications and environments it's important to keep security top of mind. Even working at a rapid pace it's important to consider what credentials and access we give to a resource. Examples of this kind of administration of roles could be access to a Windows Server or providing pull access to a Docker image from an Azure Kubernetes Cluster. These types of actions require some form of authentication and authorization in order to provide access. This guide provides you some information on getting started on understanding Azure RBAC with many of the articles you can find on Microsoft Docs and Microsoft Learn. Defining the difference Authorization and Authentication are the cornerstones of security for computing. Before we dig into examples, let's just define the words from Webster's dictionary. Authentication: an act, process, or method of showing something (such as an identity, a piece of art, or a financial transaction) to be real, true, or genuine : the act or process of authenticating something Authorization: The granting of power to perform various acts or duties To think about this in a practical sense, consider the hierarcy of a Wordpress CMS set of user roles. From Wordpress Docs, Summary of Roles Super Admin – somebody with access to the site network administration features and all other features. See the Create a Network article. Administrator – somebody who has access to all the administration features within a single site. Editor – somebody who can publish and manage posts including the posts of other users. Author – somebody who can publish and manage their own posts. Contributor – somebody who can write and manage their own posts but cannot publish them. Subscriber – somebody who can only manage their profile. When a user authenticates into Wordpress, the SQL database where user roles are stored then determines what rights the user will have when logged in. The Administrator user may be responsible for maintenance of plug-ins for the website. The admin would like to avoid users who are not part of the website maintenance plan to be able to install, delete or modify any of the plug-ins. By ensuring all of these users have a role that does not permit these rights, our website remains more reliable due to unplanned maintenance. The contributor role appears to be what's right: Contributor #Contributor delete_posts edit_posts read read Reusable Blocks In this case, the contributor role for someone who may be just posting new content update may make sense due to the specific set of roles the user is authorized to do. RBAC for Azure Role-Based Authentication (RBAC) is an authorization system built on Azure Resource Manager that provides fine-grained access management of Azure resources. Access management via RBAC on Azure allows you to better control the scope of what your users and applications can access along with what they authorized to do. What can I do with RBAC? Here are some examples of what you can do with RBAC: Allow one user to manage virtual machines in a subscription and another user to manage virtual networks Allow a DBA group to manage SQL databases in a subscription Allow a user to manage all resources in a resource group, such as virtual machines, websites, and subnets Allow an application to access all resources in a resource group Fundamentals The way you control access to resources using RBAC is to create role assignments. This is a key concept to understand – it's how permissions are enforced. A role assignment consists of three elements: security principal, role definition, and scope. User - An individual who has a profile in Azure Active Directory. You can also assign roles to users in other tenants. For information about users in other organizations, see Azure Active Directory B2B. Group - A set of users created in Azure Active Directory. When you assign a role to a group, all users within that group have that role. Service principal - A security identity used by applications or services to access specific Azure resources. You can think of it as a user identity (username and password or certificate) for an application. Managed identity - An identity in Azure Active Directory that is automatically managed by Azure. You typically use managed identities when developing cloud applications to manage the credentials for authenticating to Azure services. Azure RBAC roles Azure includes several built-in roles that you can use. The following lists four fundamental built-in roles. The first three apply to all resource types. Owner - Has full access to all resources including the right to delegate access to others. Contributor - Can create and manage all types of Azure resources but can't grant access to others. Reader - Can view existing Azure resources. User Access Administrator - Lets you manage user access to Azure resources. Different Azure resources also have built in roles to ensure secure access. By using RBAC we can ensure our DBA can log just into the development and UAT of our Azure SQL Database managed instances. We can assign them them with a the built in SQL Managed Instance Contributor role. This role permits users to manage SQL servers and databases, but not access to them, and not their security-related policies. How RBAC determines if a user has access to a resource The following are the high-level steps that RBAC uses to determine if you have access to a resource on the management plane. This is helpful to understand if you are trying to troubleshoot an access issue. A user (or service principal) acquires a token for Azure Resource Manager. The token includes the user's group memberships (including transitive group memberships). The user makes a REST API call to Azure Resource Manager with the token attached. Azure Resource Manager retrieves all the role assignments and deny assignments that apply to the resource upon which the action is being taken. Azure Resource Manager narrows the role assignments that apply to this user or their group and determines what roles the user has for this resource. Azure Resource Manager determines if the action in the API call is included in the roles the user has for this resource. If the user doesn't have a role with the action at the requested scope, access is not granted. Otherwise, Azure Resource Manager checks if a deny assignment applies. If a deny assignment applies, access is blocked. Otherwise access is granted. Next Steps You may want to learn more and get started you've got so many resources.

Microsoft Azure Hub-Spoke model by Enterprise Design 1 of 4
Microsoft Virtual Datacenter Transition to Azure (Hybrid Cloud) Microsoft Azure Hub-Spoke Architecture This Enterprise reference architecture shows how to implement a hub-spoke topology in Azure. The hub is a virtual network (VNet) in Azure that acts as a central point of connectivity to your on-premises network. The spokes are VNets that peer with the hub, and can be used to isolate workloads. Traffic flows between the on-premises datacenter and the hub through an ExpressRoute or VPN gateway connection.

Unable to select size while creating a virtual machine
Hi, Kindly assist, I'm trying to create a sql virtual machine but it's not letting me select the size. I've just started with the Azure and have free subscription. Before this I was able to create 2 windows virtual machines successfully. Thanks and Regards LipikaAzure Key Vault RBAC (Role Based Access Control) versus Access Policies!
Dear Microsoft Azure Friends, With an Azure Key Vault, RBAC (Role Based Access Control) and Access Policies always leads to confusion. Let me take this opportunity to explain this with a small example. First of all, let me show you with which account I logged into the Azure Portal. You can see this in the graphic on the top right. Now let's examine the subscription named "MSDN Platforms" by navigating to (Access Control IAM). In "Check Access" we are looking for a specific person. It is the Jane Ford, we see that Jane has the Contributor right on this subscription. So she can do (almost) everything except change or assign permissions. This is in short the Contributor right. Now we search for the Azure Kay Vault in "All resources", for this it is good to work with a filter. As you can see, Azure Key Vault (twkv77) is part of the "MSDN Platforms" subscription. We check again that Jane Ford has the Contributor Role (Inherited) by navigating to "Access Control IAM) in the Azure Kay Vault and clicking on "Role assignment". Now we navigate to "Access Policies" in the Azure Key Vault. As you can see there is a policy for the user "Tom" but none for Jane Ford. With an Access Policy you determine who has access to the key, passwords and certificates. This means that if there is no access policy for Jane, she will not have access to keys, passwords, etc. That's exactly what we're about to check. As you can see in the upper right corner I registered as "Jane Ford" (she gave me the authorization ;-)). If I now navigate to the keys we see immediately that the Jane has no right to look at the keys. There is no access policy for Jane where for example the right "List" is included, so she can't access the keys. With RBAC you control the so-called Management Plane and with the Access Policies the Data Plane. Now you know the difference between RBAC and an Access Policy in an Azure Key Vault! Sure this wasn't super exciting, but I still wanted to share this information with you. I hope this article was helpful for you? Thank you for taking the time to read this article.

Microsoft is taking another step toward bringing together its Azure Active Directory (AD) and Microsoft Account (MSA) identity services http://www.zdnet.com/article/microsofts-new-unified-log-in-experience-is-now-in-public-preview/?lipi=urn%3Ali%3Apage%3Ad_flagship3_feed%3BlsbeUu95Qy%2BN7mOlEDWuog%3D%3DList ALL ARM and ASM/Classic resources with AzureRM PowerShell?
I've noticed that the PowerShell cmdlet Get-AzureRMResource (from AzureRM module v6.12.0) returns some classic resources types, which is great and helps for what I need to do (get an inventory of all resources across all of our subscriptions). However, I'm hoping to find out if this is a dependable and complete listing of all classic resources in the subscription? or are there still classic resources that are not exposed to the ARM cmdlets/API? Some of the resource types returned are Microsoft.ClassicCompute/domainNames Microsoft.ClassicCompute/virtualMachines Microsoft.ClassicStorage/storageAccounts Note: I'm running the commands under as an ARM "Reader" RBAC role holder at the subscription level, but I do not have ASM 'administrator' or 'co-administrator' rights.
