Discover and manage AI activity by using DSPM for AI (Part 2) (AB-900 Exam Prep)

 
This post is a part of the AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals Exam Prep Hub.
This topic falls under these sections:
Understand data protection and governance tasks for Microsoft 365 and Copilot (35–40%)
   --> Identify data protection and governance risks for Microsoft 365 and Copilot
      --> Discover and manage AI activity by using DSPM for AI

Note that there are 10 practice questions (with answers) at the end of each section to help you solidify your knowledge of the material. Also, there are 4 practice tests with 30 questions each available from the hub's main page below the exam topics section.

Introduction

In Part 1, you learned how Microsoft Purview Data Security Posture Management (DSPM) for AI helps organizations discover AI activity, identify sensitive data exposure, detect oversharing, and provide visibility into how AI interacts with Microsoft 365 data.

This section (Part 2) focuses on how DSPM for AI helps administrators manage AI-related risks, integrates with other Microsoft security and compliance services, and supports secure AI adoption.

Security Recommendations Generated by DSPM for AI

One of DSPM for AI’s most valuable capabilities is providing actionable security recommendations rather than simply identifying problems.

After analyzing an organization’s AI environment, DSPM highlights areas that should be improved to reduce the likelihood of accidental data exposure or compliance violations.

Examples of recommendations include:

  • Reduce excessive SharePoint permissions.
  • Apply sensitivity labels to unclassified confidential files.
  • Configure Data Loss Prevention (DLP) policies.
  • Limit external sharing.
  • Protect highly confidential document libraries.
  • Enable auditing for AI-related activities.
  • Improve data governance before expanding AI deployments.

These recommendations help administrators prioritize improvements based on potential business impact and security risk.

Risk Prioritization

Not every security finding represents the same level of risk.

DSPM helps prioritize remediation efforts by evaluating factors such as:

  • Amount of sensitive data exposed
  • Number of users with access
  • Business importance of the data
  • Existing protection mechanisms
  • AI usage patterns
  • Permission inheritance
  • Regulatory implications

This enables administrators to address the highest-risk issues first.

For example:

RiskPriority
Public access to executive financial reportsHigh
Sensitive HR documents lacking labelsHigh
Marketing presentations shared internallyMedium
Public training documentsLow

Discovering AI-Related Data Exposure

Organizations often ask:

“If we enable Microsoft 365 Copilot today, what sensitive information could users potentially discover?”

DSPM helps answer this question.

It analyzes:

  • Existing permissions
  • Data classifications
  • Sharing configurations
  • Microsoft Graph relationships
  • Collaboration patterns

This provides insight into which sensitive data could become more discoverable through AI-assisted searches and summaries.

Remember:

Copilot does not bypass security permissions. It only accesses information that the signed-in user is already authorized to access. DSPM helps identify situations where those permissions may already be too broad.

Remediation Recommendations

After identifying risks, DSPM recommends remediation steps.

Common recommendations include:

Reduce Oversharing

Examples include:

  • Remove unnecessary SharePoint permissions.
  • Restrict Microsoft Teams membership.
  • Remove Everyone access.
  • Limit guest sharing.

Improve Data Classification

Examples include:

  • Apply sensitivity labels.
  • Enable automatic labeling.
  • Use trainable classifiers.
  • Configure sensitive information types.

Better classification improves downstream protections across Microsoft Purview.

Strengthen Data Protection Policies

DSPM may recommend:

  • Creating DLP policies
  • Encrypting confidential documents
  • Restricting downloads
  • Blocking external sharing
  • Applying retention labels

Review AI Access

Administrators may decide to:

  • Limit AI rollout to selected departments
  • Review permissions before enabling Copilot broadly
  • Reduce access to legacy repositories
  • Remove stale user accounts

Integration with Microsoft Purview

DSPM for AI does not operate as an isolated product.

Instead, it complements several Microsoft Purview solutions.

Understanding these relationships is important for the AB-900 exam.

Microsoft Purview Information Protection

Information Protection classifies and protects data.

DSPM benefits from these classifications.

For example:

A document labeled:

  • Highly Confidential
  • Internal Only
  • Financial
  • Legal

helps DSPM understand the sensitivity of AI-accessible content.

Without labels, DSPM has less context when evaluating risk.

Microsoft Purview Data Loss Prevention (DLP)

DLP prevents sensitive information from being shared inappropriately.

DSPM identifies potential risks.

DLP helps enforce policies to prevent those risks from becoming incidents.

Example workflow:

  1. DSPM discovers sensitive payroll files.
  2. DLP prevents external sharing.
  3. Organization reduces AI-related exposure.

Microsoft Purview Insider Risk Management

DSPM identifies risky data exposure.

Insider Risk Management identifies risky user behavior.

Together they help answer two different questions:

DSPM asks:

“What sensitive data could AI access?”

Insider Risk asks:

“Is someone attempting to misuse sensitive data?”

These products complement one another.

Microsoft Purview Activity Explorer

Activity Explorer provides visibility into user interactions with sensitive information.

DSPM can use Activity Explorer insights to better understand:

  • Sensitive file access
  • Label usage
  • DLP events
  • Data movement

Administrators gain a clearer understanding of how protected information is being used across Microsoft 365.

Microsoft Purview Compliance Manager

Compliance Manager focuses on regulatory compliance.

DSPM focuses on AI data governance.

Together they help organizations:

  • Reduce compliance risk
  • Improve governance
  • Meet regulatory requirements
  • Protect sensitive information used by AI

Microsoft Defender

Microsoft Defender protects identities, endpoints, applications, and cloud resources.

DSPM complements Defender by focusing specifically on AI-related data risks.

Examples:

Microsoft Defender detects:

  • Malware
  • Credential theft
  • Phishing
  • Device compromise

DSPM identifies:

  • Overshared files
  • AI exposure
  • Sensitive data visibility
  • Permission risks

AI Governance Dashboard

DSPM provides dashboards that help administrators understand their organization’s AI posture.

Typical dashboard information includes:

  • AI adoption trends
  • Sensitive data exposure
  • High-risk repositories
  • Oversharing statistics
  • AI application inventory
  • Policy recommendations
  • Governance posture

Rather than investigating individual files, administrators receive a broad organizational view.

Discovering AI Applications

DSPM helps organizations understand:

  • Which AI tools are in use
  • Which departments use them
  • Adoption trends
  • AI usage over time

Examples include:

  • Microsoft 365 Copilot
  • Microsoft Copilot Chat
  • Supported third-party AI services

This visibility helps organizations establish AI governance policies.

Investigating AI Risks

Administrators typically investigate findings by asking questions such as:

  • Which sensitive files are accessible?
  • Who has access?
  • Why do they have access?
  • Is the data properly labeled?
  • Are permissions appropriate?
  • Is the data externally shared?
  • Should additional protection be applied?

DSPM helps surface this information so administrators can make informed decisions.

Typical Investigation Workflow

A simplified investigation might follow these steps:

Step 1

DSPM identifies an overshared SharePoint site.

↓

Step 2

Administrator reviews permissions.

↓

Step 3

Sensitive files are discovered.

↓

Step 4

Sensitivity labels are applied.

↓

Step 5

Permissions are reduced.

↓

Step 6

DLP policies are enabled.

↓

Step 7

Risk is reduced before broader Copilot deployment.

Best Practices

Organizations implementing Microsoft 365 Copilot should follow several best practices.

Review Permissions Before AI Rollout

Avoid enabling Copilot before understanding existing permissions.

Classify Sensitive Data

Use Microsoft Purview Information Protection to classify important documents.

Apply Least Privilege

Users should only have access to information required for their job.

Reduce Oversharing

Review:

  • SharePoint permissions
  • Teams memberships
  • OneDrive sharing
  • External sharing

Enable DLP

Prevent accidental sharing of confidential information.

Monitor AI Adoption

Understand:

  • Who uses AI
  • Which departments use AI
  • What information AI accesses

Regularly Review Recommendations

DSPM continuously evaluates the environment.

Administrators should regularly review new recommendations as data, permissions, and AI usage evolve.

Introduction

As organizations increasingly adopt AI-powered tools such as Microsoft 365 Copilot, administrators face a new challenge: understanding how AI accesses, processes, and exposes organizational data. Traditional security tools focus on protecting users, devices, and data, but AI introduces new considerations. AI assistants can summarize documents, answer questions, generate reports, and analyze data from across an organization’s Microsoft 365 environment. If permissions are overly broad or sensitive information is poorly governed, AI can unintentionally surface information to users who already have access but should not necessarily see it in a summarized or easily discoverable form.

To address these challenges, Microsoft introduced Microsoft Purview Data Security Posture Management (DSPM) for AI, a solution designed to help organizations discover AI usage, identify potential security risks, understand data exposure, and strengthen governance before and during AI adoption.

For the AB-900 exam, you are not expected to configure DSPM for AI. Instead, you should understand:

  • What DSPM for AI is
  • Why organizations use it
  • How it discovers AI activity
  • How it helps identify risks
  • How it integrates with Microsoft Purview
  • The types of recommendations it provides

What Is Microsoft Purview DSPM for AI?

Microsoft Purview DSPM for AI is a governance and security solution that provides visibility into how artificial intelligence applications interact with organizational data.

Rather than preventing AI usage, DSPM for AI helps administrators answer important questions such as:

  • Which AI applications are employees using?
  • What sensitive information is being accessed?
  • Are AI tools exposing confidential content?
  • Are permissions overly broad?
  • Are Microsoft 365 Copilot users accessing highly sensitive data?
  • Where should security controls be strengthened?

Think of DSPM for AI as a risk discovery and governance solution specifically designed for AI workloads.

What Does “Data Security Posture Management” Mean?

The term Data Security Posture Management (DSPM) refers to continuously evaluating an organization’s data environment to identify security weaknesses before they become incidents.

DSPM focuses on questions such as:

  • Where is sensitive data stored?
  • Who has access?
  • Is the data properly classified?
  • Are security policies protecting it?
  • Could AI expose it more easily?

When AI is introduced, DSPM expands these questions to include:

  • Which AI tools are interacting with company data?
  • Which users are using AI?
  • What content is AI accessing?
  • Could AI reveal confidential information?
  • Are there oversharing risks?

Rather than reacting after a breach occurs, DSPM promotes proactive risk management.

Why Organizations Need DSPM for AI

Many organizations begin using AI before fully understanding their existing data environment.

Common issues include:

  • Excessive file permissions
  • Sensitive documents shared too broadly
  • Unlabeled confidential data
  • Legacy SharePoint permissions
  • Public Teams channels
  • Old collaboration sites
  • Inactive security policies

Without visibility into these issues, AI may legally retrieve information based on existing permissions—even though administrators were unaware those permissions existed.

DSPM for AI helps organizations discover these weaknesses before they become security problems.

Core Capabilities of DSPM for AI

Microsoft Purview DSPM for AI provides several major capabilities.

1. Discover AI Usage

DSPM identifies where AI is being used throughout the organization.

Examples include:

  • Microsoft 365 Copilot
  • Microsoft Copilot Chat
  • AI-enabled Microsoft services
  • Supported third-party AI applications

Administrators gain visibility into:

  • AI adoption
  • AI usage trends
  • Departments using AI
  • Types of AI interactions

This helps organizations understand how quickly AI is being adopted.

2. Discover Sensitive Data Exposure

DSPM evaluates whether AI has access to sensitive organizational data.

Examples include:

  • Financial reports
  • HR records
  • Customer information
  • Legal documents
  • Intellectual property
  • Healthcare information
  • Personally identifiable information (PII)

The solution identifies locations where sensitive information may be accessible through AI.

3. Identify Oversharing Risks

One of the most important concepts for the AB-900 exam is oversharing.

Oversharing occurs when users have legitimate permissions to data that administrators did not intend them to have.

For example:

  • A confidential SharePoint library inherits incorrect permissions.
  • Hundreds of employees can read executive documents.
  • Microsoft 365 Copilot can summarize those documents for anyone with existing access.

The problem is not Copilot.

The problem is the underlying permissions.

DSPM helps identify these situations.

4. Inventory AI Applications

Organizations often have many AI applications in use.

DSPM helps administrators discover:

  • Approved AI tools
  • Newly adopted AI tools
  • Shadow AI applications
  • AI usage across departments

This visibility supports governance decisions.

5. Monitor AI Interactions

DSPM can provide insights into how AI interacts with organizational content.

Examples include:

  • Documents accessed
  • Sensitive data locations
  • AI usage frequency
  • Common AI workflows
  • Business units using AI

Administrators gain a better understanding of AI usage patterns without reading users’ private prompts or monitoring employee productivity.

How DSPM for AI Discovers AI Activity

DSPM analyzes signals across Microsoft 365 services to understand AI usage.

These signals may include:

  • User activity
  • Data access
  • File classifications
  • Permissions
  • Labels
  • Microsoft Graph relationships
  • Microsoft Purview metadata

Rather than simply counting AI prompts, DSPM builds a broader picture of how AI interacts with organizational data.

Microsoft Graph’s Role

One important concept for the AB-900 exam is understanding the relationship between Microsoft Graph and DSPM.

Microsoft Graph acts as the intelligence layer connecting Microsoft 365 services.

DSPM uses Microsoft Graph signals to understand:

  • Which files users can access
  • Collaboration relationships
  • SharePoint permissions
  • Teams memberships
  • OneDrive access
  • Email relationships
  • Microsoft 365 activity

This allows DSPM to identify situations where AI could expose sensitive information because users already possess excessive permissions.

Data Sources Evaluated by DSPM

DSPM evaluates multiple Microsoft 365 services.

Examples include:

SharePoint Online

  • Sensitive document libraries
  • Overshared sites
  • Confidential folders
  • File permissions

OneDrive

  • Shared personal files
  • External sharing
  • Sensitive documents
  • Personal work data

Microsoft Teams

  • Shared files
  • Team memberships
  • Collaboration spaces
  • Shared conversations

Exchange Online

  • Email data
  • Mailbox access
  • Shared mailboxes
  • Sensitive communications

Microsoft 365 Copilot

DSPM evaluates how Copilot interacts with organizational data by examining:

  • Available permissions
  • Data sources
  • Sensitive information exposure
  • Governance controls

Types of Risks DSPM Can Identify

DSPM helps identify a variety of AI-related risks.

Overshared Content

Examples include:

  • Everyone can access HR documents.
  • Finance reports are visible to the entire company.
  • Sensitive SharePoint sites inherit incorrect permissions.

Sensitive Information Exposure

Examples include:

  • Credit card numbers
  • Passport numbers
  • Social Security numbers
  • Customer records
  • Healthcare data
  • Intellectual property

Excessive Permissions

Users frequently accumulate permissions over time.

DSPM identifies situations where users have access to more information than necessary.

This supports the principle of least privilege.

Unclassified Sensitive Data

Organizations often possess sensitive information that has never been classified.

DSPM can identify repositories containing:

  • Unlabeled confidential documents
  • Sensitive spreadsheets
  • Legal contracts
  • Financial reports

This allows administrators to apply Microsoft Purview Information Protection labels.

Shadow AI

Shadow AI refers to employees using AI tools that have not been approved by the organization.

Examples might include:

  • Public AI chat services
  • AI writing assistants
  • AI coding assistants
  • AI document summarizers

DSPM helps organizations understand where unmanaged AI usage exists so appropriate governance decisions can be made.

Key Exam Tips

For the AB-900 exam, remember these important points:

  • DSPM for AI is primarily a visibility and governance solution, not an AI blocking solution.
  • It helps organizations discover, understand, and reduce AI-related risks.
  • It identifies oversharing, sensitive data exposure, and permission issues.
  • DSPM works closely with other Microsoft Purview solutions to improve an organization’s overall AI security posture.
  • Microsoft Graph provides much of the contextual information that enables DSPM to evaluate AI data access and potential risks.
  • The goal is not to restrict productive AI use, but to ensure that AI operates within an organization’s existing security, compliance, and governance framework.

Introduction

For the AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals exam, you should understand how Microsoft Purview Communication Compliance helps organizations detect, investigate, and respond to inappropriate communications that may violate corporate policies, legal requirements, or regulatory standards. You should also understand how administrators review policy matches, investigate alerts, and take appropriate remediation actions.

What is Microsoft Purview Communication Compliance?

Microsoft Purview Communication Compliance is a Microsoft Purview solution that helps organizations detect and investigate inappropriate or risky communications across Microsoft 365 services.

Rather than preventing users from communicating, Communication Compliance monitors communications and alerts authorized reviewers when messages match organizational policies.

It helps organizations detect communications involving:

  • Harassment
  • Discrimination
  • Offensive language
  • Threats
  • Confidential information sharing
  • Regulatory violations
  • Inappropriate behavior
  • Insider risks

Communication Compliance is designed to reduce legal, compliance, and reputational risks while helping organizations meet industry regulations.

Why Communication Compliance Is Important

Organizations communicate constantly using:

  • Microsoft Teams chats
  • Teams channel messages
  • Outlook emails
  • Viva Engage (Yammer)
  • Third-party communication platforms (through supported connectors)

Without monitoring, inappropriate communications may:

  • Create hostile work environments
  • Lead to lawsuits
  • Violate government regulations
  • Expose confidential information
  • Damage an organization’s reputation

Communication Compliance provides visibility into these risks.

What Are Policy Violations?

A policy violation occurs when a communication matches conditions defined within a Communication Compliance policy.

Examples include:

  • Use of offensive language
  • Bullying or harassment
  • Sharing confidential customer information
  • Threatening another employee
  • Insider trading discussions
  • Regulatory compliance violations
  • Sharing protected intellectual property

A policy violation does not automatically mean misconduct occurred.

Instead, it means the communication requires human review.

How Communication Compliance Works

The workflow follows several stages.

Step 1: Create a Policy

Administrators create policies that define:

  • Users or groups to monitor
  • Communication locations
  • Types of violations
  • Detection conditions
  • Review workflow

Step 2: Monitor Communications

Communication Compliance continuously analyzes supported communications.

Examples include:

  • Teams messages
  • Emails
  • Viva Engage posts

Content is evaluated against policy conditions.

Step 3: Generate Alerts

If content matches a policy:

  • An alert is generated.
  • The alert appears in the Communication Compliance dashboard.
  • Reviewers receive notification.

Step 4: Human Review

Authorized reviewers investigate:

  • Original message
  • Conversation context
  • Users involved
  • Severity
  • Previous incidents

Reviewers determine whether the communication truly violated policy.

Step 5: Resolution

Reviewers choose an appropriate action, such as:

  • Resolve as compliant
  • Confirm violation
  • Escalate investigation
  • Notify HR
  • Notify legal
  • Train employee
  • Document findings

Common Types of Policy Violations

Harassment

Detects communications containing:

  • Insults
  • Bullying
  • Abusive language
  • Threats

Example:

“You’re completely useless and should quit.”

Discrimination

Detects language involving:

  • Race
  • Gender
  • Religion
  • Disability
  • Age
  • Protected characteristics

Offensive Language

Identifies:

  • Profanity
  • Hate speech
  • Offensive expressions

Sensitive Information Sharing

Detects messages containing:

  • Credit card numbers
  • Social Security numbers
  • Customer information
  • Financial records
  • Medical information

Regulatory Compliance Violations

Organizations in regulated industries monitor communications involving:

  • Insider trading
  • Market manipulation
  • Financial misconduct
  • Unauthorized disclosures

Confidential Information

Detects unauthorized sharing of:

  • Trade secrets
  • Product designs
  • Internal reports
  • Source code
  • Financial forecasts

Policy Alerts

A Communication Compliance alert contains information such as:

  • Policy name
  • Date and time
  • Severity
  • User involved
  • Communication type
  • Matched rule
  • Review status

Alerts help reviewers prioritize investigations.

Alert Severity

Organizations often classify alerts as:

Low

Minor language concerns.

Example:

A mildly inappropriate joke.

Medium

Behavior that may violate company policy.

Example:

Repeated offensive language.

High

Serious compliance concern.

Example:

Threats of violence or disclosure of confidential data.

Reviewing Policy Violations

Authorized reviewers access the Communication Compliance portal.

During review they can examine:

  • Conversation history
  • Message participants
  • Attachments
  • Policy triggered
  • Matching keywords
  • Previous incidents
  • Related alerts

Context is important because individual messages may appear harmless without surrounding conversation.

Investigation Workflow

A typical investigation includes:

  1. Open the alert.
  2. Review message details.
  3. Examine conversation context.
  4. Determine whether policy was actually violated.
  5. Assign a review outcome.
  6. Document findings.
  7. Close or escalate the case.

Possible Review Outcomes

Reviewers may classify alerts as:

  • No violation
  • Violation confirmed
  • Needs escalation
  • False positive
  • Resolved

These outcomes help improve future policy effectiveness.

False Positives

Not every alert represents an actual violation.

Examples include:

  • Educational discussions
  • Medical terminology
  • Technical documentation
  • Quoted material
  • Sarcasm
  • Context misunderstood by automated analysis

Human review remains essential.

Improving Detection Accuracy

Organizations can improve policy effectiveness by:

  • Updating keyword dictionaries
  • Using machine learning classifiers
  • Adjusting policy thresholds
  • Creating separate policies for departments
  • Reviewing false positives
  • Refining monitored user groups

Who Reviews Violations?

Communication Compliance uses role-based access control.

Typical reviewers include:

  • Compliance administrators
  • Compliance officers
  • Human Resources
  • Legal teams
  • Risk investigators

Only authorized personnel can review sensitive communications.

Privacy Considerations

Communication Compliance is designed with privacy controls.

Organizations can:

Introduction

Microsoft Purview Data Loss Prevention (DLP) helps organizations prevent the accidental or intentional exposure of sensitive information. DLP continuously monitors user activities across Microsoft 365 services and generates alerts when users violate data protection policies.

For the AB-900 exam, you should understand:

  • What Microsoft Purview DLP alerts are
  • When DLP alerts are generated
  • How administrators review alerts
  • Alert severity and prioritization
  • Investigation workflows
  • How to respond to DLP alerts
  • Integration with other Microsoft Purview and Microsoft Defender solutions
  • Best practices for managing alerts

What Is Microsoft Purview Data Loss Prevention (DLP)?

Microsoft Purview Data Loss Prevention (DLP) is a Microsoft Purview solution that helps organizations identify, monitor, and protect sensitive information from unauthorized sharing or exposure.

DLP policies monitor data stored in Microsoft 365 services such as:

  • Microsoft Exchange Online
  • Microsoft SharePoint Online
  • Microsoft OneDrive for Business
  • Microsoft Teams
  • Microsoft Defender for Cloud Apps
  • Endpoint devices (with Endpoint DLP)
  • Power BI (supported scenarios)

When a user performs an action that violates a DLP policy, the system can generate an alert.

What Is a DLP Alert?

A DLP alert is a notification generated when a DLP policy detects activity that violates organizational data protection rules.

Alerts help administrators:

  • Detect risky user behavior
  • Investigate policy violations
  • Respond to incidents quickly
  • Reduce data leakage
  • Demonstrate compliance

Alerts are one of the primary tools compliance administrators use to monitor organizational data protection.

When Are DLP Alerts Generated?

Alerts are generated when users perform actions that violate configured DLP policies.

Examples include:

  • Emailing confidential documents externally
  • Uploading sensitive files to unauthorized cloud storage
  • Copying protected files to USB devices
  • Printing highly confidential documents
  • Sharing files publicly
  • Downloading sensitive files from SharePoint
  • Copying confidential information into unmanaged applications

Not every policy generates an alert. Alert generation depends on the configured policy actions.

How DLP Detects Sensitive Information

Before generating alerts, DLP identifies sensitive content using several methods.

Sensitive Information Types (SITs)

Built-in detectors identify information such as:

  • Credit card numbers
  • Social Security numbers
  • Passport numbers
  • Driver’s license numbers
  • Bank account numbers
  • Tax identification numbers
  • Healthcare identifiers

Sensitivity Labels

Microsoft Purview Information Protection labels can identify:

  • Public
  • General
  • Confidential
  • Highly Confidential

Policies can generate alerts whenever protected documents are shared improperly.

Trainable Classifiers

Machine learning can recognize documents such as:

  • Resumes
  • Contracts
  • Source code
  • Financial reports
  • Legal documents

Exact Data Match (EDM)

Organizations can detect exact records such as:

  • Customer databases
  • Employee IDs
  • Payroll records

Components of a DLP Alert

Each alert contains detailed information to help administrators investigate the incident.

Typical alert details include:

  • User involved
  • Date and time
  • Policy name
  • Rule triggered
  • Sensitive information detected
  • File name
  • File location
  • Service involved
  • Severity level
  • User activity
  • Recommended actions

Alert Severity

DLP alerts are assigned severity levels to help prioritize investigations.

Typical levels include:

Low

Examples:

  • Minor policy violations
  • First-time incidents
  • Low-risk data exposure

Medium

Examples:

  • Multiple policy violations
  • Larger quantities of sensitive information
  • Repeated risky behavior

High

Examples:

  • Large-scale data exfiltration
  • Highly confidential information
  • Repeated attempts to bypass policies
  • Executive or privileged account violations

Administrators generally investigate High severity alerts first.

Reviewing DLP Alerts

Administrators review alerts in the Microsoft Purview portal.

The alert dashboard allows administrators to:

  • View all active alerts
  • Filter alerts
  • Search alerts
  • Sort by severity
  • Review alert details
  • Assign alerts
  • Track investigation status

Information Available During Investigation

Selecting an alert provides additional information.

Examples include:

User Information

  • Username
  • Department
  • Device
  • Location

Activity Timeline

Investigators can review:

  • File creation
  • Downloads
  • Sharing
  • Email activity
  • Printing
  • USB transfers

Policy Information

The alert identifies:

  • Which DLP policy triggered
  • Which rule matched
  • Sensitive information detected
  • Confidence level

File Details

Investigators may see:

  • File name
  • Location
  • File owner
  • Label applied
  • Number of sensitive items detected

Responding to DLP Alerts

After reviewing an alert, administrators choose an appropriate response.

Possible actions include:

Close the Alert

If the activity is determined to be legitimate or a false positive.

Investigate Further

Review:

  • User behavior
  • Related alerts
  • Audit logs
  • Endpoint activities

Escalate

Escalate high-risk alerts to:

  • Security teams
  • Compliance officers
  • Legal departments

Adjust Policies

If alerts indicate:

  • Too many false positives
  • Policy gaps
  • Incorrect thresholds

Administrators can modify DLP policies accordingly.

Educate Users

Many violations are accidental.

Organizations often:

  • Notify users
  • Provide training
  • Improve awareness

User Notifications (Policy Tips)

Instead of immediately blocking users, DLP can display Policy Tips.

Policy Tips inform users that:

  • Sensitive information was detected
  • Their action violates policy
  • They should modify their behavior

Examples include:

  • “This email contains confidential information.”
  • “Sharing this document externally violates company policy.”

Policy Tips reduce accidental violations.

Alert Lifecycle

A typical DLP alert progresses through several stages.

  1. Sensitive data is detected.
  2. DLP policy evaluates the activity.
  3. Alert is generated.
  4. Administrator reviews the alert.
  5. Investigation begins.
  6. Response action is taken.
  7. Alert is closed.

Introduction

Microsoft Purview Insider Risk Management (IRM) helps organizations detect, investigate, and respond to insider risks before they result in significant business damage. Unlike external cyberattacks, insider risks originate from individuals who already have authorized access to organizational resources. These individuals may intentionally misuse data or unintentionally expose sensitive information through careless actions.

For the AB-900 exam, you should understand:

  • What Insider Risk Management is
  • The types of risks it helps identify
  • The components used to detect insider risks
  • How risk indicators and policies work
  • How investigations are performed
  • How Insider Risk Management integrates with other Microsoft 365 security solutions
  • Common use cases

What Is Microsoft Purview Insider Risk Management?

Microsoft Purview Insider Risk Management is a Microsoft Purview solution that uses machine learning, analytics, user activity signals, and built-in privacy protections to identify potentially risky user behavior.

Its purpose is not to assume users are malicious. Instead, it identifies behaviors that could indicate:

  • Data theft
  • Intellectual property loss
  • Security violations
  • Compliance violations
  • Accidental data exposure
  • Policy violations

The solution helps security, compliance, HR, and legal teams investigate suspicious activities while respecting employee privacy.

What Is an Insider Risk?

An insider risk is any situation where someone with legitimate access to organizational systems creates risk for the organization.

Examples include:

  • An employee downloading thousands of confidential files before resigning
  • A contractor copying customer information to a USB drive
  • A user emailing sensitive documents to a personal email account
  • An employee sharing confidential information through unauthorized cloud storage
  • A user repeatedly accessing data unrelated to their job responsibilities

Not every insider risk is malicious.

Many incidents are accidental.

Examples include:

  • Sending confidential files to the wrong recipient
  • Uploading sensitive documents to public cloud storage
  • Accidentally sharing confidential Teams files

Types of Insider Risks

Microsoft categorizes insider risks into several common scenarios.

Data Theft

Occurs when users attempt to remove valuable organizational information.

Examples include:

  • Downloading confidential files

Introduction

As organizations increasingly rely on Microsoft 365 and Microsoft 365 Copilot, understanding where sensitive information resides has become a critical governance and security requirement. Sensitive data such as credit card numbers, Social Security numbers, health records, financial information, intellectual property, and confidential business documents can create significant compliance and security risks if not properly managed.

Microsoft Purview Data Explorer helps organizations discover, analyze, and understand sensitive information stored across Microsoft 365 services. It provides visibility into the location, volume, and classification of sensitive data, enabling administrators to make informed decisions about data protection, governance, compliance, and Copilot readiness.

For the AB-900 exam, you should understand the purpose of Data Explorer, how it identifies sensitive information, the types of information it can discover, and how organizations use its insights to reduce compliance and governance risks.

What Is Microsoft Purview Data Explorer?

Microsoft Purview Data Explorer is a reporting and investigation tool within Microsoft Purview that helps administrators visualize and analyze sensitive data across Microsoft 365 environments.

Data Explorer enables organizations to:

  • Discover sensitive information
  • Understand where sensitive data is stored
  • Analyze data classification results
  • Identify compliance risks
  • Support data governance initiatives
  • Validate Microsoft Purview policy effectiveness
  • Improve Microsoft 365 Copilot readiness

Rather than protecting data directly, Data Explorer provides visibility into an organization’s data landscape so administrators can take appropriate actions.

Why Data Discovery Is Important

Organizations often accumulate large amounts of data over time. Without visibility into that data, administrators may not know:

  • What sensitive information exists
  • Where the information is stored
  • Who has access to it
  • Whether it is properly protected
  • Whether regulatory requirements are being met

For example:

  • Customer records may contain personally identifiable information (PII).
  • Financial documents may contain account numbers.
  • Healthcare records may contain protected health information (PHI).
  • Contracts may contain confidential business information.

Data Explorer helps identify these risks before they become security or compliance issues.

How Data Explorer Works

Data Explorer analyzes Microsoft 365 content using classification technologies available in Microsoft Purview.

The system scans content stored in supported locations and identifies:

  • Sensitive information types
  • Sensitivity labels
  • Trainable classifiers
  • Retention labels
  • Data classifications

The results are then presented through visual dashboards and detailed reports.

Administrators can use these reports to understand the organization’s sensitive data footprint.

Data Sources Analyzed by Data Explorer

Data Explorer can analyze content across Microsoft 365 services, including:

SharePoint Online

Examples:

  • Documents
  • Team sites
  • Department sites
  • Project repositories

OneDrive for Business

Examples:

  • Personal work files
  • Shared documents
  • Business records

Exchange Online

Examples:

  • Email messages
  • Attachments
  • Mailbox content

Microsoft Teams

Examples:

  • Shared files
  • Team documents
  • Collaboration content

These locations often contain the information that Microsoft 365 Copilot accesses when generating responses.

Sensitive Information Types (SITs)

One of the primary ways Data Explorer identifies sensitive information is through Sensitive Information Types (SITs).

Sensitive Information Types are predefined patterns that identify specific categories of sensitive data.

Examples include:

  • Social Security Numbers
  • Credit Card Numbers
  • Driver’s License Numbers
  • Passport Numbers
  • Tax Identification Numbers
  • Bank Account Numbers
  • Healthcare Information

Microsoft provides hundreds of built-in sensitive information types.

Organizations can also create custom sensitive information types.

Trainable Classifiers

Data Explorer can also identify information using trainable classifiers.

Unlike pattern matching, trainable classifiers use machine learning to recognize content based on context.

Examples include:

  • Resumes
  • Contracts
  • Invoices
  • Financial documents
  • Source code

Introduction

Organizations today face increasing regulatory and compliance requirements related to data privacy, security, records management, and governance. Regulations such as GDPR, HIPAA, ISO 27001, NIST, PCI DSS, and many others require organizations to implement controls that protect sensitive information and demonstrate compliance.

Microsoft Purview Compliance Manager is a solution within Microsoft Purview that helps organizations assess, manage, and improve their compliance posture. It provides a risk-based approach to compliance by measuring how well an organization has implemented controls and by offering actionable recommendations to reduce compliance risks.

For the AB-900 exam, you should understand the purpose of Compliance Manager, how it identifies compliance risks, how compliance scores are calculated, and how organizations can use recommendations to improve their compliance posture.

What Is Microsoft Purview Compliance Manager?

Microsoft Purview Compliance Manager is a compliance management solution that helps organizations:

  • Assess compliance risks
  • Monitor compliance status
  • Track implementation of compliance controls
  • Improve regulatory compliance
  • Generate evidence for audits
  • Prioritize remediation efforts

Compliance Manager translates complex regulatory requirements into manageable improvement actions that administrators can implement within Microsoft 365.

Rather than simply reporting compliance status, Compliance Manager helps organizations actively improve compliance through continuous assessment and risk reduction.

Why Compliance Manager Is Important

Organizations must comply with numerous regulations and standards. Managing compliance manually can be difficult because:

  • Regulations frequently change
  • Multiple frameworks may apply simultaneously
  • Compliance controls span many systems
  • Evidence collection can be time-consuming
  • Auditors require documentation

Compliance Manager helps centralize compliance activities and provides visibility into compliance readiness.

Benefits include:

  • Reduced compliance risk
  • Improved governance
  • Simplified audit preparation
  • Better visibility into regulatory requirements
  • Continuous compliance monitoring
  • Prioritized remediation efforts

Understanding Compliance Risk

Compliance risk refers to the possibility that an organization fails to meet legal, regulatory, or internal policy requirements.

Examples include:

  • Improper handling of personal data
  • Missing security controls
  • Lack of retention policies
  • Inadequate access controls
  • Failure to encrypt sensitive information
  • Insufficient auditing and monitoring

Compliance Manager helps identify these risks by comparing organizational practices against compliance requirements.

Compliance Score

One of the most important concepts in Compliance Manager is the Compliance Score.

The Compliance Score is a measurement that reflects the organization’s progress toward meeting selected compliance requirements.

The score:

  • Is risk-based
  • Measures completed controls
  • Helps prioritize work
  • Changes as actions are completed

A higher score generally indicates that more compliance controls have been implemented.

However, the score does not guarantee compliance with a regulation. It serves as a management tool for tracking progress and reducing risk.

How Compliance Score Is Calculated

Compliance Manager assigns points to improvement actions.

Points are awarded when actions are completed.

Examples of actions include:

  • Enabling multifactor authentication
  • Configuring retention policies
  • Applying sensitivity labels
  • Enabling audit logging
  • Implementing access controls

Higher-risk controls typically receive more points because they contribute more significantly to risk reduction.

Assessments in Compliance Manager

An assessment measures compliance against a specific regulation, standard, or framework.

Examples include:

  • GDPR
  • ISO 27001
  • NIST
  • HIPAA
  • PCI DSS
  • Microsoft Data Protection Baseline

Each assessment contains:

  • Control objectives
  • Improvement actions
  • Testing guidance
  • Documentation requirements
  • Compliance status tracking

Organizations can use multiple assessments simultaneously.

Types of Controls

Compliance Manager evaluates different types of controls.

Microsoft-Managed Controls

These controls are implemented and managed by Microsoft.

Examples include:

  • Physical datacenter security
  • Infrastructure protections
  • Platform-level safeguards

Microsoft provides evidence showing how these controls are implemented.

Customer-Managed Controls

These controls are the responsibility of the organization.

Examples include:

  • MFA configuration
  • Retention policies
  • Access management
  • User training
  • Data classification

Administrators must implement and document these controls.

Shared Controls

Shared controls involve responsibilities divided between Microsoft and the customer.

Examples include:

  • Identity management
  • Security monitoring
  • Data protection configurations

Both parties contribute to compliance.

Improvement Actions

Improvement actions are recommendations that help organizations reduce compliance risk.

An improvement action typically includes:

  • Description of the requirement
  • Implementation guidance
  • Testing procedures
  • Documentation requirements
  • Risk impact

Examples include:

  • Enable multifactor authentication
  • Configure audit logging
  • Apply sensitivity labels
  • Restrict external sharing
  • Implement retention policies
  • Enable Data Loss Prevention policies

Completing improvement actions increases the compliance score.

Recommendations in Compliance Manager

Compliance Manager provides actionable recommendations that help organizations improve compliance.

Recommendations may involve:

Identity Security

Examples:

  • Enable MFA
  • Implement Conditional Access
  • Review privileged accounts
  • Use least-privilege access

Data Protection

Examples:

This makes audits easier because evidence is stored alongside compliance controls.

Regulatory Templates

Compliance Manager includes built-in templates for many regulations and standards.

Examples include:

  • GDPR
  • HIPAA
  • ISO 27001
  • NIST CSF
  • SOC 2
  • PCI DSS

Templates reduce the effort required to build compliance programs from scratch.

Monitoring Compliance Over Time

Compliance is not a one-time activity.

Compliance Manager supports continuous monitoring by:

  • Tracking score changes
  • Updating assessment status
  • Identifying new risks
  • Monitoring action completion
  • Highlighting outstanding requirements

Organizations can regularly review their compliance posture and address gaps.

Compliance Manager and Microsoft 365 Copilot

As organizations adopt Microsoft 365 Copilot, governance and compliance become increasingly important.

Compliance Manager can help organizations:

  • Evaluate data protection readiness
  • Review access controls
  • Verify sensitivity label deployment

Understand how Copilot uses permissions and other controls in Microsoft 365, Microsoft Purview, and Microsoft Defender to protect against risks (AB-900 Exam Prep)

 
This post is a part of the AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals Exam Prep Hub.
This topic falls under these sections:
Understand data protection and governance tasks for Microsoft 365 and Copilot (35–40%)
   --> Understand data security implications of Copilot
      --> Understand how Copilot uses permissions and other controls in Microsoft 365, Microsoft Purview, and Microsoft Defender to protect against risks

Note that there are 10 practice questions (with answers) at the end of each section to help you solidify your knowledge of the material. Also, there are 4 practice tests with 30 questions each available from the hub's main page below the exam topics section.

Introduction

One of the most important security concepts for the AB-900 exam is understanding how Microsoft 365 Copilot protects organizational data. Because Copilot can access and summarize information from across Microsoft 365, organizations must ensure that sensitive information remains protected and that users only receive information they are authorized to access.

Microsoft 365 Copilot does not operate independently of an organization’s security framework. Instead, it inherits and respects the security, compliance, governance, and protection controls already configured in Microsoft 365. These controls come primarily from:

  • Microsoft 365 permissions
  • Microsoft Entra ID
  • Microsoft Purview
  • Microsoft Defender
  • SharePoint and OneDrive security
  • Teams security controls

Together, these technologies ensure that Copilot delivers useful responses while minimizing the risk of unauthorized access, data leakage, compliance violations, and insider threats.

The Security Foundation of Copilot

Microsoft 365 Copilot is built on three key principles:

  1. Access only authorized data
  2. Respect existing security controls
  3. Apply compliance and governance policies automatically

Copilot does not create new permissions.

Instead, it uses the permissions already assigned to users and resources throughout Microsoft 365.

This means that if a user cannot access a file directly, they also cannot access that file through Copilot.

Permission Trimming: The Core Security Mechanism

The most important security concept related to Copilot is permission trimming.

Permission trimming ensures that Copilot only retrieves information the user is authorized to access.

When a user submits a prompt:

  1. Microsoft Graph searches organizational data.
  2. Existing permissions are evaluated.
  3. Unauthorized content is excluded.
  4. Only authorized information is sent to the large language model.

For example:

  • HR files are accessible only to HR employees.
  • Finance reports are accessible only to finance personnel.
  • Confidential legal documents remain restricted to legal teams.

If another employee asks Copilot about those documents, the information is not included in the response.

How Microsoft 365 Permissions Protect Data

Microsoft 365 permissions form the first layer of Copilot security.

Permissions are inherited from services such as:

  • SharePoint Online
  • OneDrive for Business
  • Microsoft Teams
  • Exchange Online
  • Microsoft Loop

Examples include:

SharePoint Permissions

Users can only access sites, libraries, folders, and files for which they have permissions.

OneDrive Permissions

Users can access their own files and content explicitly shared with them.

Teams Permissions

Copilot respects team membership and channel access.

Exchange Permissions

Emails and calendar data are only available to authorized users.

Because Copilot uses Microsoft Graph, these permissions are automatically enforced.

Role of Microsoft Entra ID

Microsoft Entra ID provides identity and access management for Microsoft 365.

Copilot relies on Entra ID to verify:

  • User identity
  • Group membership
  • Role assignments
  • Conditional Access policies
  • Authentication status

Entra ID ensures that only authenticated and authorized users can access Microsoft 365 resources.

Examples

A Conditional Access policy may require:

  • Multifactor authentication (MFA)
  • Compliant devices
  • Approved locations

If requirements are not met, users may be blocked from accessing Microsoft 365 resources and Copilot.

How Microsoft Purview Protects Data Used by Copilot

Microsoft Purview provides compliance, governance, and data protection controls.

Because Copilot works with organizational content, Purview protections automatically apply to data used by Copilot.

Sensitivity Labels

Sensitivity labels classify and protect content.

Common labels include:

  • Public
  • General
  • Confidential
  • Highly Confidential

Labels can enforce:

  • Encryption
  • Access restrictions
  • Watermarking
  • Content markings

If a document is protected by a sensitivity label, Copilot respects those protections.

Data Loss Prevention (DLP)

DLP policies help prevent sensitive information from being exposed.

Examples include:

  • Credit card numbers
  • Social Security numbers
  • Healthcare records
  • Financial information

DLP policies can:

  • Detect sensitive data
  • Block sharing
  • Generate alerts
  • Notify administrators

Copilot interactions remain subject to DLP protections.

Data Classification

Microsoft Purview can automatically classify content based on:

  • Sensitive information types
  • Trainable classifiers
  • Custom classifications

This classification helps organizations understand what information exists and where risks may be present.

Retention Policies

Retention policies ensure information is retained or deleted according to organizational requirements.

Copilot only works with content that remains available within Microsoft 365 according to retention settings.

Data Security Posture Management (DSPM) for AI

DSPM for AI helps organizations identify and reduce AI-related risks.

DSPM can:

  • Discover overshared content
  • Identify risky permissions
  • Detect exposure of sensitive data
  • Recommend remediation actions

This is especially important because Copilot may reveal risks that already exist due to improper permissions.

How Microsoft Defender Protects Copilot Environments

Microsoft Defender provides threat detection, prevention, and response capabilities.

Defender helps protect both the data Copilot accesses and the users interacting with Copilot.

Microsoft Defender XDR

Microsoft Defender XDR provides:

  • Cross-domain threat detection
  • Incident correlation
  • Security investigation
  • Automated response

It helps security teams identify attacks that may affect Copilot-accessible data.

Identity Protection

Microsoft Defender and Entra ID can detect:

  • Risky sign-ins
  • Credential theft
  • Impossible travel events
  • Suspicious account activity

Compromised identities can be blocked before attackers access Copilot.

Endpoint Protection

Microsoft Defender for Endpoint protects devices used to access Copilot.

It helps detect:

  • Malware
  • Ransomware
  • Unauthorized access attempts
  • Device compromise

Threat Intelligence

Microsoft Defender uses global threat intelligence to identify:

  • Known malicious actors
  • Emerging threats
  • Attack techniques

This helps reduce the likelihood that attackers gain access to sensitive organizational information.

Oversharing Risks and Copilot

Copilot does not create oversharing problems.

However, it can expose existing oversharing issues more efficiently.

For example:

If a confidential SharePoint folder has accidentally been shared with all employees:

  • Employees may not discover the folder manually.
  • Copilot may locate relevant content and summarize it.

Because of this, organizations should regularly review:

  • File permissions
  • Site permissions
  • Group memberships
  • Sharing settings

DSPM for AI helps identify these risks.

Security Controls Working Together

The protection of Copilot data relies on multiple layers:

Security LayerPurpose
Microsoft Entra IDIdentity verification and access control
Conditional AccessRestrict access based on risk and conditions
Microsoft 365 PermissionsControl resource access
Microsoft GraphApplies permission trimming
Microsoft PurviewGovernance, compliance, and data protection
Microsoft DefenderThreat detection and response
DSPM for AIAI-specific risk identification

These controls work together to create a secure AI environment.

Key Exam Tips

For the AB-900 exam, remember the following:

  • Copilot does not bypass existing permissions.
  • Permission trimming ensures users only see authorized content.
  • Microsoft Graph enforces access controls during data retrieval.
  • Microsoft Entra ID provides identity and access management.
  • Conditional Access can restrict Copilot access based on organizational policies.
  • Microsoft Purview protects data through sensitivity labels, DLP, classification, retention, and DSPM for AI.
  • Microsoft Defender protects identities, endpoints, and organizational resources from threats.
  • Copilot may reveal existing oversharing risks but does not create them.
  • DSPM for AI helps organizations identify and remediate AI-related data exposure risks.
