How do you verify who owns a service principal?
Description
This content discusses a method to verify the true ownership of service principals in Microsoft Entra (Azure AD) environments. It highlights challenges where the listed owner of an application may no longer be the actual responsible party. The author shares a read-only PowerShell tool that aggregates ownership data, RBAC roles, tags, relationships, and activity to provide better evidence of who currently manages the service principal. This is an experimental approach aimed at improving accuracy in ownership verification.
Reddit Discussion
I’ve seen plenty of Entra apps where the Owner field looked fine until someone actually had to touch the app.
Then it turned out the owner created it years ago, only administered it, or had nothing to do with it anymore.
I’m testing a read-only PowerShell approach that combines owners, RBAC, tags, relationships and activity to show who the evidence points to.
No automatic assignment. Just better evidence before someone makes the call.

Technical Analysis
The post introduces an experimental PowerShell-based approach to verify service principal ownership by combining multiple data points such as owners, RBAC roles, tags, relationships, and activity logs. This method addresses the issue where the recorded owner of an Entra app may be outdated or inaccurate, potentially leading to mismanagement. The tool, OwnerLensLite, is shared on GitHub as a read-only solution to provide better evidence for ownership decisions without automatic reassignment.
Potential Impact
No direct vulnerability or exploit is described. The impact relates to operational security and governance, where inaccurate ownership information can lead to mismanagement or delayed incident response. Improving ownership verification can enhance security posture by ensuring responsible parties are correctly identified.
Defensive Guidance
No patch or fix is applicable as this is not a vulnerability. The recommended approach is to use the provided read-only PowerShell tool to gather evidence-based ownership data before making changes to service principals. This helps avoid incorrect assumptions about ownership.
