Which least-privilege role enables the Microsoft Sentinel plugin in Copilot for Security?
You have an Azure subscription that uses Microsoft Copilot for Security. You create a new user named User1 and assign User1 the following roles: • The Security Operator role in Microsoft Entra • The Security Copilot Contributor role You need to ensure that User1 can use the Microsoft Sentinel plug in Copilot for Security. The solution must follow the principle of least privilege. Which role should you assign to User1?
Community Insight
The exam tests separating Copilot authorization from Sentinel workspace RBAC; the trap is assuming Security Copilot Contributor or Security Reader supplies the Sentinel data access the plug-in needs.
Microsoft Copilot for Security's Sentinel plug-in queries Sentinel data, so User1 needs a Sentinel workspace role in addition to Copilot access. Microsoft Sentinel Reader supplies the read-only access required and satisfies least privilege, unlike Sentinel Contributor or Global Administrator.
Choosing Microsoft Sentinel Contributor because the plug-in is used inside Copilot, or Security Reader because of its name; Contributor adds write permissions and Security Reader does not grant Sentinel workspace query rights.

Why the Answer Is Correct
User1 already has the Security Copilot Contributor role, which allows the user to operate Copilot, but the Microsoft Sentinel plug-in still needs access to Sentinel workspace data. Microsoft Sentinel Reader is the read-only Sentinel role that permits viewing and querying Sentinel incidents, alerts, and related data without granting change permissions. The Security Operator role in Microsoft Entra does not replace Sentinel workspace RBAC, so the Sentinel plug-in scenario still requires a Sentinel role. Microsoft Sentinel Reader is therefore the smallest role that satisfies the requirement and follows least privilege.Why the Other Options Are Wrong
Security Reader is an Azure/Defender for Cloud-style role and does not provide the Sentinel workspace read access that the Sentinel plug-in needs. Microsoft Sentinel Contributor would likely work functionally, but it grants create, edit, and management rights that exceed the read/query operations required here, so it violates least privilege. Global Administrator is far too broad, is not a Sentinel data-access role by itself, and would never be the least-privilege choice for using a Sentinel plug-in. None of these options is both sufficient and minimal when compared with Microsoft Sentinel Reader.Community Comment Notes
Mebyxu's comment selects option A and frames the decision around the "principle of least privilege", which matches the role analysis above. The comment reinforces that the Sentinel plug-in for Copilot for Security should be scoped to the minimum access needed rather than given broad administrative rights. There is no detailed counterargument in the comments, so the community note is consistent with the Sentinel Reader conclusion.Official Reference
Exam Strategy
When Copilot for Security and Microsoft Sentinel are combined, separate Copilot access roles from Sentinel workspace RBAC. Pick the smallest Sentinel role that permits the plug-in's read/query operation, and reject Global Administrator or Contributor unless the scenario explicitly requires write actions.
Frequently Asked Questions
Why doesn't Security Copilot Contributor alone allow the Sentinel plugin to work?
Copilot Contributor authorizes Copilot use, but Sentinel data access is controlled by Sentinel workspace RBAC, so User1 still needs a Sentinel role.
Why is Microsoft Sentinel Contributor not the least-privilege choice?
It grants write and management actions, while the plugin scenario only needs read/query access; Microsoft Sentinel Reader is narrower.
