03 Microsoft Identity & Security

Identity is one of the most important security boundaries in a modern Microsoft environment.

Historically, security teams focused heavily on:

Network Perimeter

Today, organizations operate across:

Cloud

SaaS

Remote Workforce

Mobile Devices

Hybrid Infrastructure

Third-Party Applications

This means access increasingly depends on:

IDENTITY

rather than simply:

Where the User Is Connected From

Part 01 — Why Identity Security Matters

Consider a traditional security model:

USER
  ↓
OFFICE
  ↓
CORPORATE NETWORK
  ↓
APPLICATION

The organization may have assumed:

Inside Network
=
Trusted

Modern environments look different:

User at Home
      |
      v
Internet
      |
      v
Microsoft Entra ID
      |
      +------> Microsoft 365
      |
      +------> Azure
      |
      +------> SaaS Applications
      |
      +------> Enterprise Applications

The organization must now determine:

Who Is This?

Can We Trust the Authentication?

What Device Are They Using?

What Are They Trying to Access?

What Privilege Do They Need?

Is the Request Risky?

Identity Is the New Security Perimeter

A useful modern security model is:

IDENTITY
   +
DEVICE
   +
CONTEXT
   +
RESOURCE
   +
RISK
       ↓
ACCESS DECISION

This is much stronger than:

Password Correct
      ↓
Allow Everything

Part 02 — Microsoft Entra ID

Microsoft Entra ID is Microsoft’s cloud identity and access-management service.

At a high level, it helps organizations manage:

Users

Groups

Devices

Applications

Authentication

Authorization

Roles

Access Policies

Workload Identities

Microsoft Entra ID Architecture

                    Microsoft Entra ID
                           |
          +----------------+----------------+
          |                |                |
          v                v                v
        Users            Devices       Applications

        Microsoft 365    Azure         SaaS Apps

Part 03 — Tenant Concept

An organization generally operates within a Microsoft cloud tenant.

Conceptually:

Organization
     ↓
Microsoft Entra Tenant
     ↓
+-----------------------+
| Users                 |
| Groups                |
| Applications          |
| Devices               |
| Roles                 |
| Policies              |
+-----------------------+

Tenant Security Questions

Ask:

Who Owns the Tenant?

Who Are the Administrators?

Which Domains Are Connected?

Which Applications Are Registered?

Which Guests Exist?

Which Policies Protect Access?

Part 04 — Identity Types

Not every identity represents an employee.

Modern environments may contain:

Human Users

Guests

Administrators

Service Accounts

Applications

Managed Identities

Automation Identities

Identity Security Principle

Every identity should have:

OWNER

PURPOSE

ACCESS

LIFECYCLE

MONITORING

If an identity has no known owner or purpose, it should be reviewed.

Part 05 — User Identities

A user identity may belong to:

Employee

Contractor

Administrator

Partner

Guest

A user may have:

Username

Authentication Methods

Groups

Roles

Applications

Licenses

Device Relationships

User Lifecycle

Use:

JOIN
 ↓
CREATE IDENTITY
 ↓
ASSIGN ACCESS
 ↓
MONITOR
 ↓
REVIEW
 ↓
CHANGE ACCESS
 ↓
REMOVE ACCESS

Security Risk — Stale Accounts

Accounts that remain after business need ends can create:

Unauthorized Access

Credential Abuse

Privilege Creep

Audit Problems

Part 06 — Groups

Groups make authorization easier to manage.

Instead of:

Alice → App Access
Bob   → App Access
Carol → App Access

prefer:

Alice
Bob
Carol
  ↓
Finance Group
  ↓
Finance Application

Security Benefit

Groups improve:

Consistency

Scalability

Role-Based Access

Access Reviews

Security Risk

Poor group governance can cause:

Privilege Creep

Example:

User Changes Role
      ↓
Old Group Access Remains
      ↓
New Group Access Added
      ↓
Excessive Permissions

Part 07 — Authentication

Authentication answers:

Who Are You?

Common authentication methods can include:

Password

Authenticator

Security Key

Certificate

Biometric

Passwordless Method

Authentication Flow

USER
  ↓
PRESENTS CREDENTIAL
  ↓
IDENTITY VERIFIED
  ↓
AUTHENTICATED

Part 08 — Authorization

Authorization answers:

What Are You Allowed to Do?

Example:

Authenticated User
      ↓
Role / Group
      ↓
Permission
      ↓
Resource

Authentication vs Authorization

Remember:

Authentication
=
Identity Verification

Authorization
=
Permission Decision

Part 09 — Multi-Factor Authentication

MFA requires more than one authentication factor.

Typical categories include:

Something You Know

Something You Have

Something You Are

Example

Password
   +
Authenticator
   ↓
MFA

Why MFA Matters

A stolen password alone may no longer be sufficient.

PASSWORD STOLEN
      ↓
SECOND FACTOR REQUIRED
      ↓
ATTACK MAY BE BLOCKED

MFA Is Not Perfect

MFA can still face threats such as:

Phishing

Session Theft

Social Engineering

Approval Fatigue

Adversary-in-the-Middle Attacks

Security strategy should therefore also consider:

Phishing-Resistant Authentication

Conditional Access

Risk Detection

Session Protection

Part 10 — Passwordless Authentication

Passwordless authentication aims to reduce dependence on reusable passwords.

Conceptually:

USER
  ↓
STRONG AUTHENTICATOR
  ↓
CRYPTOGRAPHIC VERIFICATION
  ↓
ACCESS

Potential benefits include:

Reduced Password Theft

Reduced Password Reuse

Improved User Experience

Stronger Authentication

Part 11 — Authentication Methods Governance

Organizations should manage authentication methods intentionally.

Ask:

Which Methods Are Allowed?

Who Can Register Them?

How Are New Methods Verified?

How Are Lost Authenticators Recovered?

How Are Old Methods Removed?

Security Risk

Weak recovery can undermine strong authentication.

For example:

Strong MFA
      ↓
Weak Helpdesk Reset
      ↓
Identity Compromise

Part 12 — Conditional Access

Conditional Access allows access decisions to consider context.

Conceptually:

ACCESS REQUEST
      ↓
EVALUATE SIGNALS
      ↓
USER
DEVICE
APPLICATION
LOCATION
RISK
      ↓
APPLY POLICY
      ↓
ALLOW / REQUIRE CONTROL / BLOCK

Example

Instead of:

Password Correct
      ↓
Allow

you may require:

Correct Authentication
      +
MFA
      +
Compliant Device
      +
Approved Application

Part 13 — Conditional Access Signals

Policies may conceptually evaluate:

User

Group

Application

Device

Location

Risk

Authentication Context

Potential Controls

A policy may require:

MFA

Compliant Device

Approved Authentication Strength

Additional Conditions

or:

Block Access

Part 14 — Conditional Access Design

Avoid creating policies randomly.

Use:

BUSINESS REQUIREMENT
        ↓
SECURITY RISK
        ↓
TARGET USERS / APPS
        ↓
CONDITIONS
        ↓
CONTROL
        ↓
TEST
        ↓
DEPLOY

Safety Principle

Access policies can accidentally lock administrators out.

Always use:

Controlled Testing

Emergency Access Planning

Change Management

Monitoring

Part 15 — Emergency Access

Organizations should consider how authorized administrators recover access if normal controls fail.

Emergency access identities should be:

Highly Protected

Rarely Used

Monitored

Documented

Tested

They should not become everyday administrative accounts.

Part 16 — Role-Based Access Control

RBAC assigns permissions based on roles.

Conceptually:

USER
  ↓
ROLE
  ↓
PERMISSIONS
  ↓
RESOURCE

Poor Model

Everyone
   ↓
Full Administrator

Better Model

User Administrator
      ↓
User Administration Permissions

Security Operator
      ↓
Security Operations Permissions

Least Privilege

Use:

MINIMUM ACCESS
      ↓
REQUIRED TASK
      ↓
REQUIRED TIME

Part 17 — Administrative Roles

Administrative roles can affect critical areas such as:

Identity

Security

Applications

Devices

Microsoft 365

Cloud Resources

Privileged Identity Questions

Ask:

Who Has Administrative Roles?

Why?

Is Access Permanent?

Is It Still Required?

Is MFA Enforced?

Is Activity Monitored?

Part 18 — Privileged Identity Management

Privileged Identity Management concepts help reduce permanent privileged access.

Instead of:

Administrator
=
Always Privileged

use:

Eligible User
      ↓
Administrative Need
      ↓
Activate Role
      ↓
Perform Task
      ↓
Privilege Expires

Security Benefits

This can reduce:

Standing Privilege

Privilege Exposure

Unauthorized Administrative Use

Part 19 — Just-in-Time Privilege

A mature privilege model aims for:

Right Privilege
      ↓
Right User
      ↓
Right Time
      ↓
Right Duration

This is stronger than permanent administrative access.

Part 20 — Privileged Access Reviews

Privileged roles should be reviewed periodically.

Questions:

Does This User Still Need the Role?

Does Their Job Require It?

Was It Used Recently?

Could a Smaller Role Work?

Is the Access Approved?

Part 21 — Access Reviews

Access reviews help validate whether users still require access.

They may apply to:

Groups

Applications

Guest Users

Privileged Access

Access Review Lifecycle

ACCESS GRANTED
     ↓
TIME PASSES
     ↓
REVIEW
     ↓
KEEP / MODIFY / REMOVE

Why Reviews Matter

Without reviews:

ACCESS
  ↓
ACCUMULATES
  ↓
PRIVILEGE CREEP

Part 22 — Guest Identities

External users may require access to:

Teams

SharePoint

Applications

Projects

Documents

Guest access can be legitimate, but it must be governed.

Guest Security Questions

Who Invited the Guest?

What Can They Access?

How Long Is Access Required?

Is the Guest Still Active?

Is Access Reviewed?

Can Guests Invite Others?

Guest Lifecycle

BUSINESS NEED
    ↓
INVITE
    ↓
GRANT ACCESS
    ↓

Part 23 — Enterprise Applications

Organizations may connect Microsoft Entra ID to enterprise and SaaS applications.

Conceptually:

USER
  ↓
Microsoft Entra ID
  ↓
Enterprise Application
  ↓
Business Resource

Application Security Questions

Ask:

Who Owns the Application?

Who Can Access It?

Which Permissions Exist?

Is Single Sign-On Used?

Are Privileged Permissions Required?

Is the Application Still Needed?

Part 24 — Single Sign-On

Single Sign-On allows users to authenticate through a central identity provider and access connected applications.

Conceptually:

User
  ↓
Microsoft Entra ID
  ↓
Authenticated Session
  ↓
Approved Applications

Security Benefits

SSO can improve:

Centralized Authentication

User Experience

Policy Enforcement

Monitoring

but compromise of the identity can increase impact across connected applications.

Part 25 — Application Registration

Applications may need identities to interact with Microsoft cloud services.

Conceptually:

APPLICATION
     ↓
REGISTERED IDENTITY
     ↓
AUTHENTICATION
     ↓
API / RESOURCE

This introduces:

Workload Identity Security

Part 26 — Service Principals

A service principal represents an application’s identity within a tenant context.

Security professionals should understand:

Owner

Permissions

Credentials

Usage

Lifecycle

Risk

An over-privileged application identity can be as dangerous as an over-privileged human administrator.

Part 27 — Application Credentials

Applications may authenticate using mechanisms such as:

Secrets

Certificates

Federated Credentials

Managed Identity

depending on architecture.

Security Principle

Avoid long-lived unmanaged secrets where stronger alternatives exist.

Workload Identity Lifecycle

CREATE
  ↓
ASSIGN MINIMUM PERMISSION
  ↓
MONITOR
  ↓
ROTATE / MANAGE
  ↓
REVIEW
  ↓
REMOVE

Part 28 — Managed Identities

Managed identities can help cloud workloads access supported resources without manually managing reusable application credentials.

Conceptually:

CLOUD WORKLOAD
      ↓
MANAGED IDENTITY
      ↓
AUTHORIZED RESOURCE

Security Benefit

This can reduce:

Secrets in Code

Secrets in Configuration

Manual Credential Rotation

Important

Managed identity still requires:

Least Privilege

A managed identity with excessive permissions remains a security risk.

Part 29 — Workload Identity Security

Identity security now includes both:

HUMAN IDENTITIES

and:

WORKLOAD IDENTITIES

Review:

Applications

Automation

Managed Identities

Service Principals

Integration Accounts

Workload Identity Questions

Who Owns It?

What Uses It?

What Can It Access?

How Is It Authenticated?

Is It Monitored?

Is It Still Needed?

Part 30 — Identity Protection

Identity-security platforms can use signals to identify potentially risky activity.

Examples may include:

Unusual Sign-In

Suspicious Location

Known Compromised Credentials

Unusual Behavior

Risky User Activity

Risk Model

SIGN-IN
  ↓
RISK SIGNALS
  ↓
EVALUATION
  ↓
SECURITY RESPONSE

Conceptually distinguish:

Risky Sign-In

from:

Risky User

A sign-in risk relates to a specific authentication event.

User risk relates more broadly to whether an identity may be compromised.

Investigation Questions

Which User?

Which Source?

Which Device?

Which Application?

Was MFA Successful?

Was Access Granted?

What Happened Next?

Identity logs are essential for investigation.

Useful information may include:

User

Application

Time

Source

Device

Authentication Method

Access Result

Policy Result

USER
 ↓
TIME
 ↓
SOURCE
 ↓
DEVICE
 ↓
APPLICATION
 ↓
AUTHENTICATION
 ↓
POLICY
 ↓
RESULT

Part 33 — Audit Logs

Audit logs help answer:

Who Changed What?

Examples may involve:

User Created

Group Modified

Role Assigned

Policy Changed

Application Changed

Security Importance

Identity incidents are not only about login events.

Administrative changes may be equally important.

Part 34 — Identity Incident Scenario

Scenario:

User Receives Phishing Message
        ↓
Credentials Compromised
        ↓
Suspicious Sign-In
        ↓
Attacker Accesses Cloud Application

Investigation should consider:

User

Authentication

MFA

Source

Device

Application

Session

Subsequent Activity

Part 35 — Identity and SOC Operations

Identity telemetry supports detection of:

Password Guessing

Account Takeover

Suspicious Sign-In

Privilege Changes

New Authentication Methods

Application Consent Changes

Risky Users

SOC Workflow

IDENTITY ALERT
      ↓

      ↓
TIMELINE

Part 36 — Identity and Incident Response

If identity compromise is confirmed or strongly suspected, response may include:

Disable / Restrict Identity

Revoke Sessions

Reset Credentials

Review Authentication Methods

Review Privilege

Review Applications

Review Mailbox / Data Activity

Increase Monitoring

Follow approved incident-response procedures.

Part 37 — Session Security

Modern cloud access often uses sessions and tokens after authentication.

Therefore:

Password Changed

does not always mean:

Every Existing Session
Automatically Becomes Harmless

Identity response should consider:

Session Revocation

Token Exposure

Application Access

Part 38 — Identity and Devices

Modern identity decisions may incorporate device signals.

USER
  +
DEVICE
  +
COMPLIANCE
      ↓
ACCESS

This connects directly to the endpoint-administration lesson.

Part 39 — Identity and Microsoft 365

Microsoft 365 services rely heavily on identity.

Microsoft Entra ID
      ↓
+-----------------------+
| Exchange Online       |
| Teams                 |
| SharePoint            |
| OneDrive              |
| Enterprise Apps       |
+-----------------------+

Compromised identity can therefore impact:

Email

Files

Collaboration

Applications

Part 40 — Identity and Azure

Azure also uses identity and authorization for resource access.

Conceptually:

USER / WORKLOAD
      ↓
Microsoft Entra ID
      ↓
Azure Role
      ↓
Azure Resource

This makes identity knowledge essential for cloud security.

Part 41 — Hybrid Identity

Many enterprises operate both:

Active Directory

and:

Microsoft Entra ID

A hybrid identity model may look like:

On-Premises Active Directory
           ↓
Identity Integration
           ↓
Microsoft Entra ID
           ↓
Cloud Applications

Hybrid Security Challenges

Hybrid environments can introduce:

Multiple Identity Sources

Legacy Authentication

Privilege Relationships

Synchronization Risk

Complex Troubleshooting

Part 42 — Active Directory vs Microsoft Entra ID

A simplified comparison:

Area	Active Directory	Microsoft Entra ID
Primary Model	Domain identity	Cloud identity
Common Environment	On-premises	Cloud/SaaS
Devices	Domain join	Cloud registration/join
Authentication	Domain protocols	Modern cloud authentication
Applications	Internal/domain apps	Cloud/SaaS apps

They can coexist in hybrid environments.

Part 43 — Zero Trust Identity

Zero Trust treats identity as a continuous security decision.

ACCESS REQUEST
      ↓
VERIFY IDENTITY
      ↓
VERIFY AUTHENTICATION
      ↓
CHECK DEVICE
      ↓
CHECK RISK
      ↓
CHECK RESOURCE
      ↓
GRANT MINIMUM ACCESS

Zero Trust Identity Principles

Apply:

Verify Explicitly

Least Privilege

Assume Breach

Part 44 — Identity Security Baseline

A mature organization may define baseline requirements such as:

MFA for Privileged Accounts

Controlled Administrative Roles

Access Reviews

Guest Governance

Conditional Access

Secure Authentication Methods

Workload Identity Governance

Centralized Logging

Part 45 — Identity Security Assessment

When assessing an identity environment ask:

How Many Users Exist?

How Many Guests?

How Many Administrators?

Who Has Permanent Privilege?

Is MFA Enforced?

Are Access Policies Active?

Are Dormant Accounts Present?

Are Workload Identities Controlled?

Are Risk Events Monitored?

Are Logs Retained?

Finding Example — Excessive Administrative Access

Finding:
Excessive Privileged Role Assignment

Observation:
A user retains a broad administrative role
that exceeds the requirements of their
current business function.

Risk:
Compromise or misuse of the identity could
provide unnecessary administrative access
to enterprise resources.

Recommendation:
Reduce access to the minimum role required
and use controlled time-limited privilege
where appropriate.

Finding Example — Missing MFA

Finding:
Privileged Identity Without Strong MFA

Observation:
An administrative identity can authenticate
without the organization's required strong
multi-factor authentication controls.

Risk:
Credential compromise could result in
administrative access.

Recommendation:
Require approved strong authentication for
privileged identities and monitor policy
exceptions.

Finding Example — Stale Guest Access

Finding:
Unreviewed Guest Access

Observation:
External guest identities retain access
after the associated project or business
requirement has ended.

Risk:
External users may continue accessing
corporate resources without current
business authorization.

Recommendation:
Implement recurring guest access reviews
and remove access when the business need
expires.

Finding Example — Over-Privileged Application Identity

Finding:
Application Identity Has Excessive Access

Observation:
A workload identity possesses permissions
broader than required for its documented
application function.

Risk:
Compromise of the application identity may
provide unnecessary access to enterprise
resources.

Recommendation:
Reduce the identity to the minimum required
permissions and implement ongoing ownership
and access review.

Part 46 — Practical Exercise — Identity Inventory

Create:

Identity	Type	Owner	Privileged	MFA	Review
Alice	Employee	HR/Manager	No	Yes	Current
Admin-Bob	Admin	IT	Yes	Yes	Review
Guest-1	Guest	Project Owner	No	Yes	Review
App-01	Workload	App Team	Review	N/A	Review

Ask:

Does Every Identity Have
a Known Owner and Purpose?

Part 47 — Practical Exercise — Role Design

Scenario:

Alice manages users
but does not manage security policies.

Do not assign:

Maximum Tenant Administrator

Design:

Alice
  ↓
Minimum Administrative Role
  ↓
Only Required User Management

Part 48 — Practical Exercise — Conditional Access

Scenario:

Finance Users
      ↓
Sensitive Finance Application

Security requirements:

MFA Required

Managed Device Required

Unacceptable Risk Blocked

Map:

Target Users
      ↓
Target Application
      ↓
Conditions
      ↓
Access Controls

Part 49 — Practical Exercise — Guest Access

Scenario:

External Consultant
Needs SharePoint Access
for 90-Day Project

Design lifecycle:

Business Owner Approval
      ↓
Guest Invitation
      ↓
Minimum Access
      ↓
Monitoring
      ↓
Review at Project End
      ↓

Read Access to One Resource

Avoid:

Broad Administrative Access

Design:

Application Identity
      ↓
Minimum Required Permission
      ↓
Specific Resource

Identity Troubleshooting Workflow

When a user says:

I Cannot Access the Application

use:

IDENTITY EXISTS?
      ↓
ACCOUNT ENABLED?
      ↓
AUTHENTICATION SUCCESSFUL?
      ↓
MFA SUCCESSFUL?
      ↓
ASSIGNMENT EXISTS?
      ↓
CONDITIONAL ACCESS?
      ↓
DEVICE REQUIREMENT?
      ↓
ROLE / PERMISSION?
      ↓
APPLICATION HEALTH?

Check:

Account State

Credential

Authentication Method

MFA

Risk Policy

Access Policy

Sign-In Logs

This may be:

Authorization

rather than:

Authentication

Check:

Application Assignment

Group Membership

Role

License/Entitlement

Policy

Troubleshooting Scenario 03 — MFA Not Working

Investigate:

Registered Method

User Authentication Setup

Policy Scope

Device Time/Connectivity

Authentication Logs

Recovery Method

Troubleshooting Scenario 04 — Admin Lost Access

Do not immediately disable security controls.

Investigate:

Role

Conditional Access

Authentication Method

Device State

Policy Changes

Emergency Access Procedure

Troubleshooting Scenario 05 — Application Authentication Fails

Review:

Application Identity

Credential / Certificate

Expiration

Permission

Resource

Tenant

Sign-In / Audit Evidence

Exam Preparation Strategy

Study Microsoft identity in six layers.

01 USERS & GROUPS

02 AUTHENTICATION

03 AUTHORIZATION

04 CONDITIONAL ACCESS

05 PRIVILEGED ACCESS

06 APPLICATION / WORKLOAD IDENTITIES

Common Exam Confusions

Do not confuse:

Authentication

with:

Authorization

Do not confuse:

Microsoft Entra Role

with:

Application-Specific Permission

Do not confuse:

MFA

with:

Conditional Access

MFA is an authentication control.

Conditional Access is an access decision framework that may require MFA.

Do not confuse:

Human User

with:

Workload Identity

Exam Scenario Method

Use:

01 Identify Identity Type

02 Identify Resource

03 Determine Authentication Requirement

04 Determine Permission Requirement

05 Determine Context / Risk

06 Apply Least Privilege

07 Select Appropriate Identity Control

Career Connection

Job-Readiness Skills

You should eventually be comfortable with:

User Lifecycle

Group Management

MFA

Conditional Access

Role Assignment

Privileged Access

Access Reviews

Guest Governance

Enterprise Applications

Workload Identities

Identity Logs

Risk Investigation

Interview Scenario 01

What is Microsoft Entra ID?

A cloud identity and access-management service used to manage identities, authentication, applications, devices, roles, and access to cloud resources.

Interview Scenario 02

What is the difference between MFA and Conditional Access?

MFA
=
Additional Authentication Verification

while:

Conditional Access
=
Policy-Based Access Decision

that may require MFA based on context.

Interview Scenario 03

Why is permanent administrator access risky?

Because compromise of the identity immediately exposes the attached privilege.

Time-limited privilege reduces:

Standing Administrative Exposure

Interview Scenario 04

Why should workload identities be reviewed?

Because applications and automation may have access to sensitive resources and can become high-impact attack paths if over-privileged.

Interview Scenario 05

A user authenticates successfully but cannot open an application. What does that suggest?

Investigate:

Authorization

Assignment

Conditional Access

Application Permission

License / Entitlement

rather than assuming authentication failed.
