Explanation:

Box 1: When creating a Microsoft Purview Insider Risk Management case, you must first select a risky user to investigate. The case will be built around this specific user's activities, linking alerts and risk signals to the investigation.
Box 2: The Insider Risk Management role groups determine who can access and contribute to cases:
# Admin1 (Insider Risk Management Admins) # Full admin access.
# Admin2 (Insider Risk Management Analysts) # Analysts who review cases.
# Admin3 (Risk Management Investigators) # Investigators who work on cases.
# Admin4 (Insider Risk Management Auditors) # Auditors who oversee cases.
All these roles have default access to insider risk cases in Microsoft Purview, so all four admins are added as contributors.
