The Service domains setting in Microsoft 365 Endpoint Data Loss Prevention (Endpoint DLP) allows administrators to block or allow specific domains for file uploads. The goal is to prevent users from uploading DLP-protected documents to web1.contoso.com and web2.contoso.com.

Setting the Service domains to 'web1.contoso.com and web2.contoso.com' precisely targets the two specific third-party websites, minimizing administrative effort while ensuring strict control.

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.

To track who accesses User1's mailbox, you need to enable mailbox auditing for User1. By default, Exchange mailbox auditing is not enabled per mailbox (even though it is enabled tenant-wide).

The Set-Mailbox -Identity 'User1' -AuditEnabled $true command enables audit logging for mailbox actions like:

Read emails

Delete emails

Send emails as User1

Access by delegated users

Once enabled, you can search for future sign-ins and actions in the Microsoft Purview audit logs.

To prevent the contents of files stored in Channel1 from being included in Microsoft 365 Copilot responses and ensure unauthorized users cannot access them, you should use Microsoft Purview Sensitivity Labels.

Sensitivity labels allow you to classify, protect, and restrict access to sensitive files. You can configure label-based encryption and access control policies to ensure that only authorized users can access or interact with the files in Channel1. Microsoft 365 Copilot respects sensitivity labels, meaning if a file is labeled with restricted permissions, Copilot will not use it in generated responses for unauthorized users.

To meet the requirements, you need one DLP policy with two separate DLP rules to handle the different conditions:

1. First DLP Rule (For Group1 Members): If the user is a member of Group1 and attempts to copy a file with sensitive data to a USB storage device. Allow the file copy but log the event in the audit log.

2. Second DLP Rule (For All Other Users): If any user who is NOT in Group1 attempts to copy a file with sensitive data to a USB storage device. Block the file transfer.
