Microsoft 365 Endpoint data loss prevention (Endpoint DLP) is supported only on Windows 10 and Windows 11 devices. It does not support macOS or iOS at this time.

From the provided table:

● Device1 (Windows 11) - Supported

● Device2 (Windows 10) - Supported

● Device3 (iOS) - Not supported

● Device4 (macOS) - Not supported

Thus, only Device1 and Device2 support Endpoint DLP.

To customize encrypted email in Microsoft 365, including adding a company logo, you need to modify the Office Message Encryption (OME) branding settings. The Set-OMEConfiguration PowerShell cmdlet allows you to configure branding elements such as:

● Company logo

● Custom text

● Background color

This cmdlet is used to update existing OME branding settings, ensuring that encrypted emails sent from your organization include the required customizations.

To ensure that encrypted email messages sent to external recipients can be revoked or expire within seven days, you need to configure a sensitivity label with encryption settings in Microsoft Purview Information Protection. A sensitivity label allows you to encrypt emails and documents, set expiration policies (e.g., emails expire after 7 days), and enable email revocation

How to configure it?

● Go to Microsoft Purview compliance portal → Information Protection

● Create a sensitivity label

● Enable encryption and configure the content expiration policy

● Publish the label to users

To review a Microsoft 365 Copilot usage report, you need to use Data Security Posture Management for AI (DSPM for AI) in the Microsoft Purview portal. DSPM for AI provides insights into AI-related activities, including Copilot usage, risk assessments, and data security posture related to AI interactions within Microsoft 365.

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.

Marking Tailspin_scanner.exe as "Unsanctioned" in Microsoft Defender for Cloud Apps only blocks its usage in cloud-based activities (such as accessing SharePoint, OneDrive, or Exchange Online). However, it does not prevent a locally installed application on Windows 11 devices from accessing sensitive files.

To block Tailspin_scanner.exe from accessing sensitive documents while allowing it to access other files, the correct solution is to use Microsoft Purview Endpoint Data Loss Prevention (Endpoint DLP) and add Tailspin_scanner.exe to the Restricted Apps list.

Endpoint DLP allows you to block specific applications from accessing sensitive files while keeping general access available. Restricted Apps List in Endpoint DLP ensures that Tailspin_scanner.exe cannot open, copy, or process protected documents, but it can still function normally for non-sensitive content.

The action "SiteRenamed" for SharePoint is covered under the AuditRetention4 policy, which applies to User1 and retains logs for 9 months.

The action "Send" for ExchangeItem is covered under the AuditRetention2 policy, but this policy applies only to User1. Since User2 is not covered under a specific policy, the default retention period for audit logs in Microsoft Purview is 90 days.

AutoApply1 is an auto-labeling policy that applies RLabel1 to Group1. Auto-labeling policies can apply retention labels across group mailboxes, SharePoint Online sites, and Teams channel messages if they are configured for group resources.

Retention1 is a retention policy applied to Group2. Retention policies for Microsoft 365 groups apply to all group resources, including group mailboxes, SharePoint Online teams sites, and Teams channel messages.

Since both AutoApply1 and Retention1 affect entire groups, they apply to all associated resources: group mailbox, SharePoint Online teams site, and Teams channel messages.

Statement 1 - No. User1 is included in JIT protection. File1.docx is on Device1, which is onboarded to Microsoft Defender. However, File1.docx has not been evaluated for file classification, meaning JIT cannot enforce protection on it. If User2 signs in to Device2 and attempts to attach File2.pdf to an email, JIT will block the action.

Statement 2 - No. User2 is not configured for JIT protection (JIT does not apply to them). File2.pdf has been evaluated for classification, but since User2 is not included in JIT protection, no blocking occurs. If User3 attempts to copy File3.xlsx to a network share, JIT will generate an audit event.

Statement 3 - No. User3 is included in JIT protection. However, Device3 is not onboarded to Microsoft Defender, meaning JIT protection cannot enforce actions on it. File3.xlsx has not been evaluated, so even if the device were onboarded, JIT would not have classification data to act upon.

To meet the requirement that all administrative users must be able to create Microsoft 365 sensitivity labels, we need to assign the Sensitivity Label Administrator role to the correct users.

Sensitivity Label Administrator Role Responsibilities

This role allows users to:

● Create and manage sensitivity labels in Microsoft Purview.

● Publish and configure auto-labeling policies.

● Modify label encryption and content marking settings.

Users that must be assigned the Sensitivity Label Administrator role:

● Admin2 (Compliance Data Administrator)

● Admin3 (Compliance Administrator)

● Admin1 (Global Reader) (should be assigned this role to fulfill the requirement that all admins can create labels).

Understanding DLP Policy Impact on File Access

The DLP policy (DLPpolicy1) applies to Site2 and restricts access when:

● Content contains SWIFT Codes.

● Instance count is 2 or more.

Files that remain accessible (not restricted by DLP):

● File1.docx (Contains only 1 SWIFT Code → Below restriction threshold)

User access after DLP policy is applied:

User1 (Site Owner):

● Has higher privileges and can override DLP restrictions (through admin intervention).

● Can access 2 files (File1.docx + override access to another file).

User2 (Site Visitor):

● Has read-only access but DLP blocks access to restricted files.

● Can only access 1 file (File1.docx), since all others are restricted.

To detect and protect confidential documents, we need a custom rule to identify project codes that start with 999 (since they are classified as confidential).

Box 1: A Sensitive Info Type (SIT) allows Microsoft Purview DLP policies to recognize structured data (e.g., project codes). DLP policies require a sensitive info type to detect content based on patterns, keywords, or dictionary terms. A sensitivity label alone does not define detection logic—it is used for classification and protection after content is identified.

Box 2: Since project codes follow a structured 10-digit pattern, we should use a Regular Expression (Regex) to match project codes that start with 999.

Example Regex pattern:

999\d{7}

This pattern detects a 10-digit number starting with "999".

Understanding Site4's Retention Policies:

● Site4RetentionPolicy1 deletes items older than 2 years from creation. If a file was created on January 1, 2021, it would be deleted after January 1, 2023.

● Site4RetentionPolicy2 retains files for 4 years from creation. If a file was created on January 1, 2021, it will be kept until January 1, 2025, but not deleted after that (policy states "Do nothing").

Statement 1 - Yes, because Site4RetentionPolicy2 ensures files are retained for 4 years.

Statement 2 - Yes, because Site4RetentionPolicy2 retains the file for 4 years (until January 1, 2025).

Statement 3 - No, because retention is only for 4 years (until January 1, 2025). After that, the policy does "nothing," meaning the file is no longer recoverable after that period.

The goal is to automatically label documents in Site1 that contain credit card numbers. To achieve this, we need a sensitivity label with an auto-labeling policy based on a sensitive info type that detects credit card numbers.

Step 1: Create a Sensitive Info Type

● A sensitive info type is needed to detect credit card numbers in documents.

● Microsoft Purview includes built-in sensitive info types for credit card numbers, but we can also create a custom one if necessary.

Step 2: Create a Sensitivity Label

● A sensitivity label is required to classify and protect documents containing sensitive information.

● This label can apply encryption, watermarking, or access controls to credit card data.

Step 3: Create an Auto-Labeling Policy

● An auto-labeling policy ensures that the sensitivity label is applied automatically when credit card numbers are detected in Site1.

● This policy is configured to scan files and automatically apply the correct sensitivity label.

The requirement states that all Microsoft 365 data for users must be retained for at least one year. In Microsoft 365, retention policies must be configured for each type of data storage.

Step 1: Identifying Where Data is Stored

From the case study, users store data in the following locations:

● SharePoint Online sites

● OneDrive accounts

● Exchange email

● Exchange public folders

● Teams chats

● Teams channel messages

Since these locations fall under two broad categories:

● Microsoft Exchange data (Emails, Public folders)

● SharePoint, OneDrive, and Teams data

Step 2: Required Retention Policies

1️. A single retention policy can cover:

● SharePoint Online

● OneDrive

● Microsoft Teams

2. A second retention policy is required for:

● Exchange (Emails & Public Folders)

Thus, the minimum number of retention policies required to meet the requirement is 2.

Microsoft 365 retention policies can be applied broadly across multiple services with just two policies:

● One for Exchange & Public Folders

● One for SharePoint, OneDrive, and Teams

There's no need for separate policies for each individual workload unless different retention durations are required, which is not stated in the requirement.
