Azure Active Directory (Azure AD) Conditional Access is an intelligent policy enforcement tool that helps ensure your network’s safety. With Azure AD Conditional Access, you establish rules that automatically enforce defined access controls when certain conditions are met.
When integrating Azure AD Conditional Access with Azure Virtual Desktop, the goal is to create and implement policies that protect the connections to your Azure Virtual Desktop instances. This particular aspect is crucial when preparing for the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam.
Setting up Azure AD Conditional Access policies
Before you begin, make sure you have an active Azure license that includes Azure AD Premium, which is required for Conditional Access.
Follow these steps to set up Azure AD Conditional Access policies:
- Navigate to the Azure portal: Open the Azure portal (portal.azure.com) and sign in with an account with administrative rights.
- Go to Azure Active Directory: From the left navigation pane, select Azure Active Directory.
- Create a new policy: In the Azure Active Directory pane, under Security, select Conditional Access. Click “+ New policy” to create a new policy.
- Name your policy: Under Assignments, select Users and groups. Here you can define the specific users and/or groups that this policy will apply to.
- Set conditions: You can set conditions based on factors such as users or groups, cloud apps, devices, locations, and risks detected by Azure AD Identity Protection.
- Define access controls: Under Access Controls, configure what is required to grant or block access. You can set Grant or Block access and configure the requirements.
- Enable policy: Select “On” under Enable policy, then click “Save.” Your policy is now active.
Examples of Azure AD Conditional Access Policies
For better understanding, here’s an example scenario:
Let’s say we want to create a policy where users must verify their identity through multi-factor authentication (MFA) when accessing Azure Virtual Desktop outside of the corporate network.
First, we define under Assignments the users and/or groups this policy should apply to. Then, we set the conditions – for Cloud apps, we will include Azure Virtual Desktop, and for Locations, we’ll configure All Networks excluding Trusted Locations. Lastly, under Access Controls, we’ll define our requirement as ‘Require MFA’ and enable the policy.
Configuring Azure AD Conditional Access policies for Azure Virtual Desktop
Also, when configuring Azure AD Conditional Access for Azure Virtual Desktop, there are certain things to consider:
- Session mode: You can either apply the Conditional Access policy at the start of a user’s session (the default mode) or have it continuously enforce the policy throughout the user’s session.
- Interference with user experience: Always ensure that your policies are not too restrictive in a way that can interfere with user productivity. Use the ‘Report-Only’ mode to test your policies before enforcing them.
- Risk-based Conditional Access policies: Leveraging risk signals from Azure AD Identity Protection can help in defining more dynamic and adaptive policies.
Azure AD Conditional Access is a powerful tool for securing connections to Azure Virtual Desktop. As you work towards passing the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam, understand how to plan and implement Azure AD Conditional Access policies effectively.
Remember, Azure AD Conditional Access is just one part of a larger security strategy. Together with other features like Azure AD Identity Protection and Azure AD Privileged Identity Management, you can build a robust security framework for your Azure Virtual Desktop environment.
