I thought it will be a quick Google search to find a PowerShell script that will give a report on applications published via Entra application proxy, but I found only scripts (link1, link2, link3) using the AzureAD PowerShell module – so I decided to write a new version using Graph PowerShell.

I spent ‘some’ time exploring this web sign-in thing and thought to share the results of my research. History Web sign-in is available since Windows 10 1809 (link) as a private preview feature and it was restricted to TAP (temporary access pass) There was a time when Web sign-in was not limited to TAP, so […]

Workload identity (including service principals) security keeps bugging me, especially the password credentials (aka client secret). I’m sure there are scenarios where this is the only option, but I see environments where these are used just because it is easier to implement. And one day I woke up and realized how dangerous it can be […]

When talking about Azure AD security, we tend to put less focus on service principals/app registrations*. But when we take into consideration that these principals can have assigned API permissions and “static” credentials (certificate or password) and that these credentials in the wrong hands can cause serious damage, we may change our attitude.* While “App […]

The story in short: one of my customers asked me if it is possible to generate a report on all content in Office365 shared externally. Doing some searches I found the following solutions:– Run the sharing reports on each site and each OneDrive (link, link)– Run reports based on audit logs (link) While these reports […]

This will be a short post about a recent finding: AzureAD Conditional Access policies created from template may miss from your backups if not using Graph API beta endpoint. TL;DR– When you create a Conditional Access policy using the “New policy from template (Preview)” button, the policy will not show when querying policies using the […]

There are several methods for monitoring Azure AD App registration expiration (like PowerAutomate or Azure Logic Apps) but these methods require extra licences or an Azure subscription. The PowerShell way is free and it only requires a new registration in AzureAD. TL;DR The script:
