One of my previous posts covered a “basic” way to track secure score changes using Graph API with application permissions.

In the November 2023 – What’s New in Microsoft Entra Identity & Security w/ Microsoft Security CxE identity episode, a public preview feature of Entra Workload ID premium license was presented (link) which was actually announced on November 9th (link). I really love the idea of restricting application key credentials to a predefined list of […]

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 […]

Scenario: the business is now convinced that computers should be managed centrally (either with Active Directory or Azure Active Directory) instead of having WORKGROUP computers.Problem: after joining to (Azure)AD, users will have a new profile created. Gone are their settings, wallpaper, pinned icons, etc. You need to note these settings, copy the files to the […]

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:

When there are multiple administrators in an AzureAD tenant, it is inevitable that one may change settings in Conditional Access policies – without notifying everyone involved. To keep track of changes you could regualarly check the AzureAD audit logs, or have an automation for it. I may be a bit old-fashioned, but I prefer to […]

In a large corporate environment, it’s not unusual to have several Azure AD Named Locations (should it be trusted or not). It is even more challenging to keep track of these locations when there are several admins managing the environment. I thought it would be useful to have a script to determine if an IP […]

Update: as the AzureAD PowerShell is being deprecated, I made an updated version which can be found here Backing up AAD Conditional Access policies is relatively straightforward with Get-AzureADMSConditionalAccessPolicy cmdlet (don’t forget to update your AzureAD module if the cmdlet is not recognized). In this post, I want to share my own backup “solution” which […]
