Introduction

That is an excellent next topic for the AB-900 exam because it combines SharePoint governance, Microsoft Purview, and Copilot data security. Although the feature continues to evolve, the exam focuses on understanding what the report is, when to use it, and what problems it helps administrators solve, rather than memorizing every UI step.

Why Data Access Governance Matters

One of the largest security challenges in Microsoft 365 is oversharing. Over time, organizations accumulate millions of files, thousands of SharePoint sites, and numerous Microsoft Teams workspaces. Permissions often become increasingly complex as users:

  • Share files externally
  • Create anonymous sharing links
  • Grant access to “Everyone”
  • Add guests to Teams
  • Break inheritance on folders
  • Forget to remove temporary permissions

As organizations adopt Microsoft 365 Copilot, overshared content becomes an even greater concern because Copilot can surface information that a user already has permission to access—even if that access was unintentionally granted.

Microsoft provides Data Access Governance (DAG) capabilities in SharePoint to help administrators discover, understand, and remediate excessive access before it becomes a security issue.

What is Data Access Governance?

Data Access Governance is a collection of reporting and analysis capabilities within SharePoint Advanced Management that helps administrators answer questions such as:

  • Which sites are accessible by everyone?
  • Which files are overshared?
  • Which sites have external users?
  • Which sites contain highly sensitive information?
  • Which permissions may expose confidential content?
  • Which sites should be reviewed?

Rather than examining permissions one site at a time, administrators receive organization-wide visibility.

Primary Goals of Data Access Governance

Data Access Governance helps organizations:

  • Discover overshared sites
  • Review permissions
  • Reduce excessive access
  • Identify high-risk collaboration
  • Improve Microsoft 365 security posture
  • Prepare for Microsoft 365 Copilot deployment
  • Reduce accidental data exposure
  • Support compliance initiatives

Why It Is Important for Microsoft 365 Copilot

Microsoft 365 Copilot never ignores permissions.

Instead, it retrieves content using the same security model that governs Microsoft 365.

If a user has permission to open a document manually, Copilot can potentially reference that document when generating responses.

For example:

Suppose Human Resources accidentally grants the entire company read access to salary spreadsheets.

Without Copilot:

  • Most employees may never discover the files.

With Copilot:

A user might ask:

“Summarize employee compensation data.”

Because the files are already accessible, Copilot could retrieve them.

The problem is not Copilot—it is the underlying permissions.

Data Access Governance helps identify these permission problems before they become security risks.

What the Data Access Governance Report Shows

The report provides administrators with visibility into SharePoint permissions and sharing configurations across the tenant.

Common information includes:

  • Site owners
  • Site sensitivity
  • External sharing status
  • Number of members
  • Anonymous links
  • Organization-wide access
  • Guest access
  • Sharing activity
  • Permission inheritance
  • Access patterns
  • High-risk sites
  • Overshared content indicators

Rather than searching manually, administrators can prioritize the highest-risk locations.

Types of Oversharing That Can Be Identified

The report can identify situations such as:

Organization-wide access

Sites accessible by:

  • Everyone
  • Everyone except external users
  • Large security groups

These sites often expose more content than intended.

Anonymous Links

Files shared through links that require no authentication.

These links may remain active long after they are needed.

Guest Access

Sites containing:

  • External users
  • Partner accounts
  • Vendor accounts

Administrators can verify whether guest access is still appropriate.

Excessive Sharing

Examples include:

  • Large numbers of shared files
  • Broad sharing permissions
  • Public document libraries
  • Open collaboration spaces

Sensitive Sites

The report can identify sites that contain:

  • Financial information
  • HR records
  • Legal documents
  • Intellectual property
  • Customer information

Combined with Microsoft Purview sensitivity labels, administrators gain better visibility into where important information resides.

Typical Workflow

Administrators generally follow this process:

Step 1

Open SharePoint administration tools.

Step 2

Generate or review a Data Access Governance report.

Step 3

Review identified risks.

Examples:

  • Overshared sites
  • External sharing
  • Everyone permissions
  • Sensitive content

Step 4

Investigate high-risk sites.

Questions include:

  • Does this access need to exist?
  • Are guests still required?
  • Is inheritance broken?
  • Should permissions be reduced?

Step 5

Take corrective action.

Possible actions include:

  • Remove permissions
  • Restrict sharing
  • Apply sensitivity labels
  • Disable anonymous links
  • Reduce guest access
  • Educate site owners

Step 6

Run reports regularly to verify improvements.

Relationship with Microsoft Purview

Data Access Governance works alongside Microsoft Purview.

Purview answers questions such as:

  • What sensitive data exists?
  • How is it classified?
  • Which labels are applied?
  • Are DLP policies triggered?

SharePoint Data Access Governance answers:

  • Who can access the data?
  • Is the data overshared?
  • Which sites expose information?
  • Which permissions should be reviewed?

Together they provide both:

  • Content awareness
  • Permission awareness

Relationship with Microsoft 365 Copilot

Data Access Governance helps administrators prepare for Copilot by reducing permission-related risks.

Benefits include:

  • Finding overshared SharePoint sites
  • Identifying unnecessary permissions
  • Reducing broad access
  • Reviewing guest sharing
  • Protecting confidential information
  • Improving search security
  • Supporting Zero Trust principles

Best Practices

Microsoft recommends that organizations:

  • Review sharing reports regularly.
  • Audit external access periodically.
  • Minimize “Everyone” permissions.
  • Remove unused guest accounts.
  • Apply sensitivity labels to important sites.
  • Use Microsoft Purview DLP alongside SharePoint governance.
  • Educate site owners on responsible sharing.
  • Review high-risk collaboration sites before deploying Copilot broadly.
  • Follow the principle of least privilege.
  • Continuously monitor permission changes.

Common Exam Tips

Remember these key points:

  • Data Access Governance focuses on permissions and access, not document content.
  • It helps identify oversharing across SharePoint.
  • It is especially valuable before deploying Microsoft 365 Copilot.
  • Copilot respects existing Microsoft 365 permissions.
  • Oversharing is a permissions problem, not a Copilot problem.
  • Reports help administrators prioritize high-risk sites for remediation.
  • Data Access Governance complements Microsoft Purview rather than replacing it.

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.

Licensing Considerations

For the AB-900 exam, you are not expected to memorize licensing details, as licensing can change over time.

However, you should understand these general principles:

  • DSPM for AI is part of the Microsoft Purview family.
  • Advanced governance and AI security capabilities may require appropriate Microsoft licensing.

Introduction

For the AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals exam, you should understand how Microsoft Purview Activity Explorer helps administrators investigate user activities involving sensitive information. Activity Explorer provides visibility into how sensitive data is accessed, shared, modified, labeled, or protected across Microsoft 365 services. It is an important investigative tool for identifying potential data protection and governance risks.

What Is Microsoft Purview Activity Explorer?

Microsoft Purview Activity Explorer is an investigation tool that displays activities involving sensitive information and Microsoft Purview protection technologies across Microsoft 365.

Rather than preventing actions, Activity Explorer helps administrators answer questions such as:

  • Who accessed sensitive information?
  • Which files contained sensitive data?
  • Was a sensitivity label applied or removed?
  • Did a Data Loss Prevention (DLP) policy trigger?
  • Was confidential information shared externally?
  • When did a particular activity occur?

Activity Explorer provides a searchable history of events so administrators can investigate potential compliance and security incidents.

Purpose of Activity Explorer

The primary purpose of Activity Explorer is to provide visibility into how organizational data is being used and protected.

It helps organizations:

  • Investigate compliance incidents
  • Monitor sensitive information usage
  • Validate Microsoft Purview policy effectiveness
  • Support audits
  • Identify risky user behavior
  • Understand how sensitive data moves throughout Microsoft 365

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
      --> Identify policy violations generated by Communication Compliance

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

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:

  • Limit reviewer access
  • Use pseudonymization (where supported)
  • Restrict investigations
  • Audit reviewer actions
  • Follow regional privacy laws

Integration with Other Microsoft Security Solutions

Communication Compliance works alongside several Microsoft security solutions.

Microsoft Purview Insider Risk Management

Communication Compliance findings may support insider risk investigations involving suspicious employee behavior.

Microsoft Purview Data Loss Prevention (DLP)

DLP prevents unauthorized sharing of sensitive information, while Communication Compliance reviews the content and context of communications.

Microsoft Purview Information Protection

Sensitivity labels applied to documents help reviewers understand the sensitivity of shared information.

Microsoft Defender

Security incidents and user risk signals can complement Communication Compliance investigations.

Communication Compliance and Microsoft 365 Copilot

  • 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

  • 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.

Integration with Microsoft Purview Solutions

DLP works closely with other Microsoft Purview capabilities.

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
  • Copying files to USB devices
  • Printing sensitive documents
  • Emailing proprietary information externally

Data Leakage

Sensitive information leaves the organization unintentionally.

Examples include:

  • Uploading files to personal cloud storage
  • Sending confidential documents externally
  • Sharing protected files publicly

Security Policy Violations

Users violate established organizational security rules.

Examples include:

  • Disabling security controls
  • Using unauthorized applications
  • Circumventing compliance policies

Compliance Violations

Employees violate legal or regulatory requirements.

Examples include:

  • Sharing regulated financial records
  • Mishandling healthcare information
  • Improperly accessing customer records

Departing Employee Risks

A common scenario involves employees preparing to leave the organization.

Potential indicators include:

  • Large file downloads
  • Increased file copying
  • Unusual external sharing
  • Mass printing
  • Accessing previously unused repositories

How Insider Risk Management Works

Insider Risk Management follows a multi-stage process.

Step 1: Collect Activity Signals

  • Risk indicators
  • User context

This reduces false positives.

Step 3: Generate Risk Alerts

If suspicious behavior exceeds configured thresholds:

  • An alert is created.
  • The alert receives a severity level.
  • Investigators can review supporting evidence.

Step 4: Investigate

Compliance administrators review:

  • Timeline of events
  • User activities
  • File operations
  • Email actions
  • Device activities
  • Related alerts

Step 5: Respond

Possible actions include:

  • Escalating investigations
  • Assigning cases
  • Collecting evidence
  • Alerting management
  • Applying additional protections
  • Closing false positives

Risk Indicators

Risk indicators are behaviors that contribute to a user’s overall risk score.

Examples include:

File Activities

  • Downloading files

Policies are based on templates.

Common templates include:

  • Data leaks
  • Data theft
  • Security policy violations
  • Departing employees
  • Risky browser usage
  • Priority user monitoring

Policies allow organizations to customize detection based on their business needs.

Risk Scores

Each user activity contributes to a risk score.

Higher scores indicate more concerning activity.

Factors influencing scores include:

  • Number of risky actions
  • Severity of activities
  • Frequency
  • Historical behavior
  • Machine learning analysis

Risk scores help investigators prioritize the most serious incidents.

Alerts

When policy thresholds are exceeded, alerts are created.

Alerts typically include:

  • User involved
  • Policy triggered
  • Activity timeline
  • Risk level
  • Supporting evidence
  • Recommended investigation steps

Alert severity may include:

  • Low
  • Medium
  • High

Cases

Investigators can promote alerts into investigation cases.

Cases centralize:

  • Evidence
  • User activity
  • Timeline
  • Notes
  • Investigation status
  • Assigned investigators

This allows multiple reviewers to collaborate.

Privacy by Design

Microsoft designed Insider Risk Management with employee privacy in mind.

Privacy protections include:

  • Role-based access control

Introduction

Data is one of an organization’s most valuable assets. However, not all data carries the same level of sensitivity or business value. Some information can be shared publicly, while other information must be protected because it contains financial records, intellectual property, customer data, healthcare information, or confidential business plans.

Microsoft Purview Data Classification helps organizations identify, categorize, and protect sensitive information throughout Microsoft 365. Data classification is a foundational capability that enables organizations to understand their data landscape, apply appropriate protections, meet compliance requirements, and securely adopt AI technologies such as Microsoft 365 Copilot.

For the AB-900 exam, it is important to understand how Microsoft Purview classifies data, the tools involved, and how classification supports security, compliance, governance, and AI readiness.

What Is Data Classification?

Data classification is the process of identifying and categorizing information based on its:

  • Sensitivity
  • Confidentiality
  • Regulatory requirements
  • Business value
  • Risk level

Classification allows organizations to answer questions such as:

  • Which files contain sensitive information?
  • Where is confidential data stored?
  • Who can access regulated data?
  • Which content should be protected or retained?
  • What data can Copilot safely access?

Microsoft Purview automates much of this process through built-in detection technologies.

Why Data Classification Is Important

Without data classification, organizations often struggle to:

  • Identify sensitive information
  • Apply consistent protections
  • Meet compliance requirements
  • Prevent data loss
  • Govern AI access to information

Benefits of data classification include:

  • Improved data visibility
  • Better security controls
  • Regulatory compliance
  • Reduced risk of data breaches
  • More effective data governance
  • Safer use of Microsoft 365 Copilot

Microsoft Purview Data Classification Components

Microsoft Purview uses several components to classify information.

Sensitive Information Types (SITs)

Sensitive Information Types are predefined patterns used to identify sensitive data.

Examples include:

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

Microsoft provides hundreds of built-in SITs covering numerous countries and regions.

Example

A document containing a U.S. Social Security Number may automatically be detected and classified as sensitive content.

Trainable Classifiers

Trainable classifiers use machine learning to identify content based on context rather than exact patterns.

Examples include:

  • Resumes
  • Source code
  • Contracts
  • Financial documents
  • Healthcare records
  • Intellectual property

Unlike SITs, trainable classifiers examine the meaning and context of content.

Example

A contract may be identified even if it does not contain a specific keyword or sensitive number.

Content Explorer

Content Explorer allows administrators to:

  • View classified content
  • See where sensitive data exists
  • Investigate data locations
  • Analyze classification results

This tool helps organizations understand their data environment.

Activity Explorer

Activity Explorer provides visibility into:

  • Labeling activities
  • Classification actions
  • DLP events
  • User interactions with sensitive data

Administrators can investigate how classified information is being used.

Types of Data Classification

Organizations typically classify data into categories such as:

ClassificationDescription
PublicInformation intended for everyone
GeneralEveryday business information
InternalInformation for employees only
ConfidentialSensitive business information
Highly ConfidentialCritical or restricted information

Organizations can customize classifications based on their requirements.

Classification and Sensitivity Labels

Data classification often works together with Sensitivity Labels.

Classification identifies the data.

Sensitivity labels protect the data.

Example

Microsoft Purview detects:

  • Credit card information
  • Customer account numbers

A sensitivity label is then automatically applied:

  • Confidential
  • Highly Confidential

The label can then:

  • Encrypt the file
  • Restrict access
  • Apply watermarks
  • Block unauthorized sharing

Automatic Data Classification

Microsoft Purview can automatically classify information using:

Pattern Matching

Detects predefined sensitive information.

Examples:

  • Credit card numbers
  • Social Security numbers
  • Passport numbers

Machine Learning

Uses trainable classifiers to recognize content types.

Examples:

  • Contracts
  • Legal documents
  • Source code

Keyword Detection

Identifies content based on specific words or phrases.

Examples:

  • Confidential
  • Internal Use Only
  • Proprietary Information

Data Classification and Microsoft 365 Copilot

Data classification is particularly important for Copilot deployments.

Organizations often ask:

What information can Copilot access?

Copilot respects:

  • User permissions
  • Sensitivity labels
  • Compliance controls

Proper data classification helps organizations:

  • Understand their data
  • Identify overshared content
  • Protect confidential information
  • Reduce AI-related risks

Classification improves confidence when deploying AI solutions.

Data Classification and Compliance

Many regulations require organizations to identify and protect sensitive information.

Examples include:

  • GDPR
  • HIPAA
  • PCI DSS
  • SOX
  • Various privacy laws

Microsoft Purview classification helps organizations:

  • Locate regulated data
  • Apply protections
  • Support audits
  • Demonstrate compliance

Data Classification and Data Loss Prevention (DLP)

Data classification works closely with DLP policies.

Process

  1. Purview identifies sensitive content.
  2. Content is classified.
  3. DLP policies evaluate the classification.
  4. Protective actions occur.

Examples:

  • Block file sharing
  • Restrict email transmission
  • Alert administrators
  • Notify users

Without classification, DLP cannot effectively identify sensitive content.

Data Classification and Insider Risk Management

Classified data helps Insider Risk Management identify risky activities involving:

  • Financial records
  • Intellectual property
  • Customer information
  • Confidential business data

This improves risk detection and investigation capabilities.

Common Data Classification Use Cases

Financial Information Protection

Introduction to Microsoft Purview Sensitivity Labels

Microsoft Purview Sensitivity Labels are classification and protection mechanisms that help organizations secure sensitive information across Microsoft 365. Labels enable organizations to identify important data and apply protections automatically or manually.

Sensitivity labels are part of Microsoft Purview Information Protection and support the principles of:

  • Data classification
  • Data protection
  • Compliance
  • Governance
  • Secure collaboration
  • AI readiness for Microsoft 365 Copilot

Instead of securing locations only, sensitivity labels secure the data itself, allowing protections to remain with content wherever it travels.

Why Sensitivity Labels Matter

Organizations often handle information with varying levels of confidentiality:

  • Public documents
  • Internal business data
  • Financial records
  • Human resources information
  • Customer data
  • Intellectual property
  • Legal documents

Sensitivity labels provide a consistent method for:

  • Identifying content sensitivity
  • Applying encryption
  • Restricting access
  • Adding visual markings
  • Preventing accidental exposure
  • Supporting compliance requirements

How Sensitivity Labels Work

A sensitivity label can be applied to:

  • Documents
  • Emails
  • Microsoft Teams
  • Microsoft 365 Groups
  • SharePoint sites
  • OneDrive content

Labels can be:

Manually applied

Users choose the appropriate label.

Automatically applied

Microsoft Purview detects sensitive information and assigns labels automatically.

Recommended

Users receive suggestions to apply a label.

Common Label Hierarchies

Organizations frequently create labels such as:

LabelIntended Audience
PublicAnyone
GeneralEmployees
InternalInternal users only
ConfidentialSpecific departments
Highly ConfidentialRestricted users

Labels are customizable and vary by organization.

Core Protection Capabilities

A sensitivity label may configure:

Encryption

Controls who can open content and what actions they can perform.

Examples:

  • View only
  • Edit allowed
  • Print blocked
  • Copy restricted

Content Markings

Visual indicators help users recognize sensitivity.

Examples:

  • Headers
  • Footers
  • Watermarks

Access Restrictions

Limits content access to:

  • Individuals
  • Groups
  • Departments
  • External users

Expiration Settings

Content access can expire after a specified period.

Major Use Cases for Sensitivity Labels

1. Protecting Confidential Documents

Organizations can label:

  • Financial statements
  • Contracts
  • Product designs
  • Strategic plans

Example:

A “Highly Confidential” label encrypts a document and restricts access to executives only.

2. Protecting Email Messages

Labels can secure email communication.

Example:

An HR manager sends salary information using a “Confidential – HR” label that:

  • Encrypts the email
  • Restricts forwarding
  • Prevents printing

3. Supporting Microsoft 365 Copilot

Copilot respects existing permissions and sensitivity labels.

If a document is labeled:

  • Confidential
  • Highly Confidential
  • Executive Only

Copilot only uses content that the user already has permission to access.

Sensitivity labels therefore help organizations prepare data safely for AI experiences.

4. Securing External Collaboration

Organizations can share files externally while maintaining protection.

Example:

A company sends a proposal to a partner:

  • External recipients can read it.
  • Forwarding is blocked.
  • Printing is disabled.

Protection travels with the document.

5. Meeting Regulatory Compliance Requirements

Sensitivity labels help support:

  • GDPR
  • HIPAA
  • Financial regulations
  • Privacy laws
  • Industry-specific requirements

Organizations can demonstrate that sensitive information receives appropriate protection.

6. Preventing Accidental Data Exposure

Users sometimes unintentionally send sensitive information.

Labels provide:

  • Classification awareness
  • Visual reminders
  • Automated protection

Example:

A user sending customer data receives an automatic recommendation to apply a Confidential label.

7. Protecting Intellectual Property

Engineering designs, research documents, and proprietary information can be restricted.

Example:

Only members of the Research department can access files labeled “R&D Confidential.”

8. Applying Visual Classification

Headers, footers, and watermarks immediately show sensitivity.

Examples:

  • INTERNAL USE ONLY
  • CONFIDENTIAL
  • HIGHLY CONFIDENTIAL

These markings help employees recognize handling requirements.

9. Labeling Containers

Sensitivity labels can be applied to:

  • Microsoft Teams
  • Microsoft 365 Groups
  • SharePoint sites

Container labels can control:

  • Guest access
  • Privacy settings
  • External sharing
  • Unmanaged device access

Example:

A Team labeled “Confidential Project” automatically disables guest access.

10. Supporting Data Loss Prevention (DLP)

   --> Identify the core security features of Microsoft 365 services
      --> Understand App registrations and Enterprise apps

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

Modern organizations rely on applications to access Microsoft 365 resources, integrate with cloud services, and automate business processes. Microsoft Entra ID (formerly Azure Active Directory) provides identity and access management capabilities not only for users but also for applications.

Two important concepts administrators must understand are:

  • App registrations
  • Enterprise applications

Although these terms are closely related, they represent different objects within Microsoft Entra ID. Understanding their purposes and differences is important for the AB-900: Microsoft 365 Copilot and Agent Administration Fundamentals exam.

Why Applications Need Identities

Just as users require identities to sign in and access resources, applications also need identities.

Applications may need to:

  • Access Microsoft Graph APIs.
  • Read SharePoint data.
  • Send email through Exchange Online.
  • Authenticate users.
  • Integrate with Microsoft 365 services.
  • Support Microsoft 365 Copilot and agents.

Microsoft Entra provides these capabilities through app registrations and enterprise applications.

What Is an App Registration?

An App Registration defines an application’s identity within Microsoft Entra ID.

When developers register an application, Entra creates:

  • An Application (client) ID
  • A directory object representing the application
  • Authentication settings
  • Redirect URIs
  • API permissions
  • Secrets or certificates (optional)

Think of an app registration as the blueprint or template for an application.

Common Uses

  • Custom business applications
  • Web applications
  • Mobile applications
  • APIs
  • Microsoft Graph integrations
  • Copilot extensions and agents

Key Components of an App Registration

Application (Client) ID

A globally unique identifier that identifies the application.

Example:

Application ID: 7a12b8c3-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Applications use this ID during authentication.

Directory (Tenant) ID

Identifies the Microsoft Entra tenant where the application resides.

Redirect URI

Specifies where authentication responses are sent after users sign in.

Examples:

Secrets and Certificates

Applications may authenticate themselves using:

  • Client secrets
  • Certificates

These credentials should be protected because they function similarly to passwords.

API Permissions

Applications often require access to Microsoft services.

Examples:

  • Read user profiles
  • Access calendars
  • Read SharePoint files
  • Send email

Permissions can be granted by users or administrators depending on the permission type.

Types of API Permissions

Delegated Permissions

The application acts on behalf of a signed-in user.

Example:

A Teams app reads the user’s calendar using that user’s permissions.

Characteristics:

  • Requires a signed-in user.
  • Limited by the user’s permissions.

Application Permissions

The application runs independently without a user.

Example:

A background process scans SharePoint sites across the organization.

Characteristics:

  • No user sign-in required.
  • Usually requires administrator consent.

What Is an Enterprise Application?

An Enterprise Application is the service principal created from an app registration.

Think of the enterprise application as the instance of the application inside a tenant.

Enterprise applications manage:

  • User assignments
  • Sign-in permissions
  • Single sign-on settings
  • Conditional Access policies
  • Application access controls
  • Monitoring and sign-in logs

Simple Comparison

ObjectPurpose
App RegistrationDefines the application
Enterprise ApplicationRepresents the application inside the tenant

Relationship Between App Registrations and Enterprise Applications

When an application is registered:

  1. An app registration is created.
  2. A corresponding enterprise application (service principal) is created.
  3. Users and permissions are managed through the enterprise application.

One application registration can have multiple enterprise applications across different tenants.

Service Principals

A service principal is the identity used by an application within a specific tenant.

The service principal:

  • Authenticates the application.
  • Receives permissions.
  • Appears as an enterprise application.

For exam purposes:

Enterprise Application = Service Principal

Enterprise Applications and Single Sign-On (SSO)

Enterprise applications support Single Sign-On.

Users can:

  • Sign in once.
  • Access multiple applications.
  • Use Microsoft Entra credentials.

Benefits include:

  • Improved user experience.
  • Reduced password fatigue.
  • Centralized identity management.

Enterprise Applications from External Vendors

Not all enterprise applications originate from your organization.

Examples include:

  • Salesforce
  • ServiceNow
  • Workday
  • Zoom
  • Adobe

These SaaS applications appear as enterprise applications inside Microsoft Entra and can use SSO.

User Assignment

Administrators can control which users may access an enterprise application.

Options include:

Everyone

All users can access the application.

Selected Users or Groups

Only assigned users receive access.

This supports least privilege and Zero Trust principles.

Conditional Access and Enterprise Applications

Conditional Access policies can target applications.

Examples:

  • Require MFA for Salesforce.
  • Block access from unmanaged devices.
  • Restrict access by location.
  • Allow only compliant devices.

This helps secure application access.

Consent and Permissions

Applications request permissions when first used.

Two forms of consent exist:

User Consent

Users approve low-risk delegated permissions.

Example:

Allowing an app to read basic profile information.

Admin Consent

Administrators approve permissions that affect the entire organization.

Example:

Granting an app permission to read all mailboxes.

Admin consent helps protect sensitive organizational data.

Monitoring Enterprise Applications

Administrators can review:

  • Sign-in logs
  • Failed sign-ins
  • User assignments
  • Permission grants
  • Conditional Access results

These tools help troubleshoot and improve security.

Common Administrative Tasks

Administrators frequently:

  • Add enterprise applications.
  • Configure SSO.
  • Assign users and groups.
  • Review permissions.
  • Grant admin consent.
  • Remove unused applications.
  • Investigate sign-in logs.
  • Apply Conditional Access policies.

Security Best Practices

Use Least Privilege

Grant only required permissions.

Review Permissions Regularly

Remove unnecessary permissions.

Require MFA

Protect access to sensitive applications.

Remove Unused Applications

Reduce attack surface.

Use Group Assignments

Simplify management.

Monitor Sign-In Activity

Identify unusual behavior.

Importance for Microsoft 365 Copilot and Agents

Copilot extensions, plugins, and custom agents often rely on:

  • App registrations
  • Microsoft Graph permissions
  • Enterprise applications
  • User consent
  • Authentication and authorization

Understanding these concepts helps administrators securely deploy AI solutions within Microsoft 365.

Key Exam Points

Remember these AB-900 concepts:

  • App registrations define an application’s identity.
