A company uses Salesforce and Box as cloud apps. The security team discovers that a third-party OAuth app with excessive permissions was granted access to Salesforce data by a user. They want a solution that can detect such risky OAuth apps and automatically revoke their permissions based on policy. Which Microsoft security solution provides this capability?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Microsoft Defender for Cloud Apps
Correct. Defender for Cloud Apps can discover and assess OAuth apps, and with its OAuth app policies, it can automatically revoke permissions for high-risk apps.
B
Distractor review
Microsoft Defender for Endpoint
Incorrect. Defender for Endpoint protects endpoints from malware and attacks but does not manage OAuth app permissions in cloud apps.
C
Distractor review
Microsoft Defender for Office 365
Incorrect. Defender for Office 365 protects against threats in email, Teams, and SharePoint, but does not cover third-party cloud apps like Salesforce.
D
Distractor review
Microsoft Sentinel
Incorrect. Sentinel is a SIEM that can ingest logs from various sources and create detection rules, but it does not have built-in OAuth app governance policies.
Common exam trap
Common exam trap: answer the scenario, not the keyword
