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 […]

So recently I was planning on requiring authentication stenghts in a Conditional Access policy – more precisely requiring Windows Hello for Business – when I realized that I’m not 100% sure that every user will meet this requirement. I wanted to make sure everybody has WHfB enrollment and that it is actively in use – […]

Recently, John Savill* uploaded a video on this very cool feature and I thought to give it a try when I realized I have no Log Analytics integration enabled, so no Workbooks for me 🙁[*big fan of John’s videos, pure gold] This is not fair to those who only use Microsoft 365 products or who […]

Disclaimer: the following configurations require Microsoft Entra Workload Identities Premium licence (link) In my previous post, I highlighted the risks of using password credentials for apps and how to spot client secret usage for service principals. This post will focus on limiting password lifetime for apps (scoped to tenant or specific application level) which can […]

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 Edge Drop is a really wonderful feature, but my inner data protection officer was bugging me to investigate if it is safe in an enterprise (or SMB) environment. There are several options to protect corporate data (labels, App Protection Policy, DLP policies, etc.) but not every business is lucky enough to afford the required […]

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 […]
