Document Entra ID Conditional Access Policies with the IdPowerToys App

Manual and Automatic Documentation of Conditional Access Policy Settings as PowerPoint Presentation

Windows has its Power Toys and now Microsoft’s identity management team is getting into the act with Identity Power Toys (idPowerToys), an app to help Azure Active Directory power users get work done. The initial release of the app is limited to a Conditional Access Documentator, a useful tool to read the configuration of conditional access policies fromEntra ID and generate documentation in the form of a PowerPoint presentation (using components from Syncfusion). The IdPowerToys GitHub repository is available for all to browse and contribute to.

Conditional access policies set conditions and criteria for Entra ID to examine inbound connections to decide if a connection should be accepted or rejected. A typical conditional access policy is one that requires accounts to use multi-factor authentication (MFA). The policy could even define that the authentication method used for the MFA response should be a certain strength. For instance, an SMS response is unacceptable but a response from the Microsoft Authenticator app is OK.

Only its creators love the GUI used to manage conditional access policies in the Microsoft Entra (Azure AD) admin center. It’s easy to make mistakes and people have been known to lock themselves out by implementing conditions that they can’t meet. It’s also easy to create conditions that make the daily interaction between people and apps miserable, such as cranking up the sign-in frequency for connections. Many different policies might exist in large enterprise tenants, and it can be hard to understand the flow that a connection traverses as Entra ID applies conditions from the set of policies. Examination of records in the sign-in log throws some light onto the situation but can be a drag.

The Conditional Access Documentator

Enter the Conditional Access Documentator, the first IdPowerToys app. The app is available online and supports two modes:

• Automatic generation: IdPowerToys retrieves of conditional access policies using an enterprise app created in the tenant’s Entra ID and generates a PowerPoint presentation. You can opt to mask different elements of the output. For instance, if you choose to mask policy names, IdPowerToys generates its own version of the policy name based on what it does. If you choose to mask user names, IdPowerToys outputs their account identifier instead of their display name.
• Manual generation: A tenant administrator runs a PowerShell command or uses the Graph Explorer to retrieve the JSON-formatted information about conditional access policies and pastes the results into a text box. IdPowerToys uses the information to create the PowerPoint file. Masking isn’t supported for manual generation.

An enterprise app is a registered Entra ID app owned by another tenant that creates an instance of the app in other tenants. Alongside the app instance, Entra ID creates a service principal to hold the permissions needed by the app. An administrator must grant consent before the app can use the permissions to access Entra ID to fetch the information about conditional access policies.

Some will be uneasy about granting an app permissions like Directory.Read.All (read information about accounts, groups, and other objects) and Policy.Read.All (read all policy information for the organization). However, as shown in Figure 1, the permissions are delegated, not application, which means that an account holding an administrator role must sign-into the app to use the permissions.

If you’re uneasy about creating an enterprise app with permissions, use the manual generation method and run the Invoke-GraphRequest cmdlet to fetch the data and output it to the clipboard. This command only works when run by an administrator:

Invoke-GraphRequest -Uri 'https://graph.microsoft.com/beta/policies/conditionalAccessPolicies' -OutputType Json | Set-Clipboard

Figure 2 shows the results retrieved from the Graph pasted into the IdPowerToys app.

In either case, the PowerPoint presentation generated to document conditional access policies is the same. For my tenant, which has 12 conditional access policies (not all in use), the app generated a 609 KB file with 13 slides (one title slide and one for each policy), divided into sets of enabled and disabled policies. Within a set, policies are sorted by last modified date, so the policy with the most recent modification appears first.

Figure 3 shows a presentation generated by IdPowerToys with details of a conditional access policy in the slide. This is a common policy to require MFA for guest access, with tweaks to require a certain authentication strength and to set the sign-in frequency to 90 days. You can see that the policy is enabled.

Visualize Conditional Access Policies Differently

Conceptually, generating documentation for conditional access policies isn’t difficult. Graph API requests exist to fetch the information and after that it’s a matter of parsing the conditions, actions, access controls, and session controls to output in your desired format. Some might prefer their documentation in Word. I think PowerPoint is just fine. IdPowerToys delivers documentation that just might help organizations visualize, clarify, and rationalize their conditional access policies, and that’s a good thing.
