Microsoft Purview Insider Risk Management flags high-impact users based on various risk factors, including role, access to confidential data, and influence within an organization. Let's analyze each user:

User1 (Regional Manager, assigned Reader role, manages department managers)

Risk Factors:

● Holds a managerial position (regional manager).

● Manages multiple department managers, indicating organizational influence.

● Access to critical business information.

Flagged? -Yes (Managerial role and access to confidential data).

User2 (HR department manager, no Microsoft Entra roles, manages HR department users)

Risk Factors:

● Manages HR department users, meaning they likely handle sensitive employee data.

● HR roles are often considered high-risk due to access to personal and payroll data.

Flagged? -Yes (HR role and access to sensitive employee data).

User3 (Developer, reports to User2, only user in compliance, assigned Compliance Administrator role)

Risk Factors:

● Compliance Administrator role grants access to sensitive security and regulatory data.

● Only person in the compliance department, meaning they hold a critical role.

● Potentially high impact on compliance and security settings.

Flagged? -Yes (Privileged Compliance Administrator role).

User4 (Assistant to User1, no Entra roles, handles confidential data on behalf of User1)

Risk Factors:

● Handles a high volume of confidential data on behalf of a regional manager.

● Assistants with access to sensitive data are considered insider risk candidates.

Flagged? -Yes (High access to sensitive information).

Since all four users fit high-impact criteria (managerial roles, privileged compliance access, handling sensitive data), Microsoft Purview Insider Risk Management will flag all of them.
