Security

Microsoft recently announced their new FIDO2 provisioning APIs within Microsoft Entra ID. While users can register their FIDO2 keys fairly easily with a Temporary Access Pass, the new API allows admins to register keys on behalf of a user. This can be extremely handy in onboarding scenarios or in case a new key needs to be shipped to a vendor or contract worker. The Microsoft APIs support every vendor of FIDO2 (passkeys), but Yubico has made some extra effort to… 

In case you didn’t get the latest memo, Microsoft is tightening the security around the Azure and Microsoft 365 admin portals by enforcing multifactor authentication for all interactive sign-ins. In this post, I will try to answer all the questions about this change, as there seem to be a lot of questions on social media lately. If you still have questions after reading this post (which I’m sure you have), please reach out so I can add your Q&A to… 

Conditional Access include and exclude groups cannot be messed with. As we have seen in a previous blog post, this will impact your security posture. But what if you need to create a legitimate escape for operational purposes? Take this use case, for example: You’ve enforced phishing-resistant MFA for your admin accounts on all apps (you are a rockstar!). Still, some applications do not support MSAL/WAM, or you have legacy scripts that use Internet Explorer 11 for authentication, so your… 

Bypassing Conditional Access is easy. That’s because most Conditional Access policies rely on Entra ID Security Groups. Since Entra ID is very “flat” by default, every admin with group management permissions can add or remove members to ANY group. That’s why we want to handle our include and exclude groups carefully. This idea does not stand alone and is also mentioned in this marvelous article by Thomas Naunheim. If you’re new to Restricted Management Administrative Units, I suggest reading this… 

It’s here! A long-awaited feature in Microsoft 365 is finally there. Now, in public preview, organizations can add another phishing-resistant credential to their arsenal: device-bound passkeys. DISCLAIMER: This feature is currently in public preview. Everything you read in this blog post is subject to change and may be outdated soon. Always check the current documentation on Microsoft Learn to keep track of changes. Images in this post might be slightly different in reality. What is a device-bound passkey? First, let’s… 

Entra ID protection is an excellent feature amongst the other services in the Entra Premium P2 license SKU. Microsoft Entra ID Protection detects identity-based risks so that admins can mitigate those risks. Users can also self-mitigate risk. To evaluate and asses this feature, you could, of course, simulate a bunch of risky events, as described here. Using a TOR browser and the developer tools in the browser, you can quickly bump up your sign-in risk to trigger the policies in… 

This post is all about the hack on Microsoft by Midnight Blizzard (NOBELIUM, Cozy Bear, APT29)A lot has been said already, and this event has many angles. This post is focused on one part: What can Entra/Microsoft 365 admins do to prevent such an attack? I don’t have all the answers (certainly not!) but I feel the urge to bundle all the resources so that the community can find guidance during this snowstorm. I did not find any time to… 

Microsoft Entra Global Secure Access brings a new control to Conditional Access. By installing the Global Secure Access Client on (hybrid) Entra joined devices and enabling Global Secure Access signaling for Conditional Access, admins can now work with a new condition: All Compliant Network locations (Preview) That means we can add another layer to our tenant to prevent token theft and replay. Let’s have a first look. Prepare the lab The first step is to activate Global Secure Access in…
