Project BICEP! I am with you on this one. stronger passwords with Specops Password Policy. Azure has a notion of a Service Principal which, in simple terms, is a service account. My recommendation would be to remove the contributor role assignment and add the correct level. However, they are two representations of applications in Azure AD. Once done hit Add Permissions. Select App registrations and + New registration. This means that you can use it to connect to Azure without using a password.

Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Each of these types of credentials has its advantage and applicable usage scenarios. Similarly, lets remove the System Assigned MI of the VM and use a User Assigned one in the next example (an Azure Resource can only be linked to one or the other, not both): As you notice, the Managed Identity object gets immediately removed from Azure AD. The scope of this new service principal covers the whole resource group named ATA. This as we first need to generate a certificate. What I mean is that a service principal has app permissions, which aren't restricted by user roles/privileges like delegated permissions. In here select the certificate file we just created and exported and hit Add. We are now able to connect with PowerShell and the service principal to this log analytics workspace. Which is the Application ID and Tenant ID. These accounts are frequently used to run a specific scheduled task, web application pool or even SQL Server service. The official Microsoft docs strongly discourage the practice of user accounts employed as service accounts. It's the identity of the application instance. Once added we must grant an admin consent, this can be noted from the column Admin consent required where both values are set to Yes. If random users are logging in as service accounts, you have bigger problems. The code below uses the New-AzRoleAssignment cmdlet to assign the scope and role of the Azure service principal. Labels: Access Management Azure Active Directory (AAD) Identity Management More information about the difference between Service Principals and App Registrations can be found here. An Azure Service Principal can be created using any traditional way like the Azure Portal, Azure PowerShell, Rest API or Azure CLI. Let's wrap up January with some great community posts about pipelines and organization moves! And most admins probably use a fully privileged user account (called a service account) to set up the credential requirements for scripts. The Request API permissions screen on the right will open, in here we can select the Microsoft Graph API. In the application context, no one is signed in. Azure AD is the trusted Identity Object store, in which you can create different Identity Object types. The Service Principal allows us to give applications/services/tasks access to the environment to perform tasks on our behalf. A service principal, on the other hand, is treated more like a domain user within Azure. These include using the Azure Portal, Azure Active Directory Admin Center, Azure AD PowerShell, Azure CLI, and Azure PowerShell. Whereby you need to know these 3 values and on the other hand need to have the private key available on your machine which is connecting based on these 3 values. To create a managed identity, go the Azure portal and navigate to the managed identity blade. Also, you can use the Get-AzRoleAssignment -ObjectID $sp.id command to get the role assignments of the Azure service principal. A Service Principal is the identity object in Azure Active Directory that allows roles to be assigned to various objects (resources). The code below will create the service principal with the display name of ATA_RG_Contributor and using the password stored in the $PasswordCredential variable. Consider the alternative of a service principal: Both require some kind of secret to authenticate, whether a user password or client secret. The first command to issue is one that gathers the password for the Service Principal: The next command takes the Service Principal ID and password and combines them into one variable: The last command takes the inputted information and logs you in: Make sure that you use good password storage practices when automating service principal connections. Instead, they recommend using service principals or managed identities. Most software-as-a-service (SaaS) applications accommodate multi-tenancy. Which specific conditional auth policy do you have in mind? Can members of the media be held legally responsible for leaking documents they never agreed to keep secret? the Windows Hello for Business authentication methods as you can see below via the command: Get-MgUserAuthenticationWindowsHello -UserID johny.bravo@identity-man.eu. An Azure service principle is like an application, whose tokens can be used by other azure resources to authenticate and grant access to azure resources. Ensure the permission type for application is supported. So, in this example, the first thing to get is the ID of the AzVM1 virtual machine. A multi-tenant application is homed in a tenant and has instances in other tenants. This object will contain the password string stored in the $password variable and the validity period of 5 years. Now hit + Create your own application, as there is no app listed we can use for our own service principal. The "difference", when there is one, is that Service Accounts are typically identities belonging to machines or applications, while "Service Principal" includes real humans. This is especially useful if the password must meet a complexity requirement. Below screenshot shows what it looks like for an Azure Web App Resource: To complete the sample scenario, lets go back to Azure Key Vault, and specify another Access Policy for this User Assigned Managed Identity: After saving the changes, the result is that now both the Azure Virtual Machine as well as the Web App having the User Assigned Managed Identity assigned to them can read our keys and secrets from Azure Key Vault. Sometimes you want to take action based on that, but not usually. Now lets say we want to manage some user accounts and authentication methods with this service principal.

A Service Principal could be looked at as similar to a service account-alike in a more traditional on-premises application or service scenario. The biggest difference between a service account and a service principal is that it cant be used for regular web based sign-ins. Typical use cases where you would rely on a Service Principal is for example when running Terraform IAC (Infrastructure as Code) deployments, or when using Azure DevOps for example, where you define a Service Connection from DevOps Pipelines to Azure; or basically any other 3rd party application requiring an authentication token to connect to Azure resources. If you can't use a managed identity, grant a service principal enough permissions and scope to run the required tasks. Not really anything special. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Lets add the permissions for that on the Service Principal we created. And in a somehow similar way, you would use the same concept from about any other third party solution, keeping in mind that the technical parameter field names might differ a bit from what the Azure CLI command provides as output. Then, assign a role to the identity. to configure some permissions I cant limit it down to very specific permissions via MS Graph.
