You have a Microsoft 365 tenant and 500 computers that run Windows 11. The computers are onboarded to Microsoft Purview.
You discover that a third-party application named Tailspin_scanner.exe accessed protected sensitive information on multiple computers. Tailspin_scanner.exe is installed locally on the computers.
You need to block Tailspin_scanner.exe from accessing sensitive documents without preventing the application from accessing other documents.
Solution: From the Microsoft Defender for Cloud Apps, you mark the application as Unsanctioned.
Does this meet the goal?

Correct Answer:
B
Marking Tailspin_scanner.exe as 'Unsanctioned' in Microsoft Defender for Cloud Apps only blocks its usage in cloud-based activities (such as accessing SharePoint, OneDrive, or Exchange Online). However, it does not prevent a locally installed application on Windows 11 devices from accessing sensitive files.
To block Tailspin_scanner.exe from accessing sensitive documents while allowing it to access other files, the correct solution is to use Microsoft Purview Endpoint Data Loss Prevention (Endpoint DLP) and add Tailspin_scanner.exe to the Restricted Apps list.
Endpoint DLP allows you to block specific applications from accessing sensitive files while keeping general access available. Restricted Apps List in Endpoint DLP ensures that Tailspin_scanner.exe cannot open, copy, or process protected documents, but it can still function normally for non-sensitive content.
