Skills Measured in the SC-900 Exam

The SC-900 exam blueprint divides the content into four principal domains, each with its percentage weight in the assessment.

1. Describe the Concepts of Security, Compliance, and Identity (10–15%)

This segment lays the philosophical foundation. Candidates must understand what security, compliance, and identity mean in a Microsoft cloud context. Topics include Zero Trust, shared responsibility, and defense-in-depth strategies.

2. Describe the Capabilities of Microsoft Entra (25–30%)

Focused on Microsoft’s identity and access management platform, this domain introduces users to authentication, authorization, lifecycle management, conditional access, and privileged access control using Microsoft Entra ID (formerly Azure Active Directory).

3. Describe the Capabilities of Microsoft Security Solutions (30–35%)

This portion centers on Microsoft Defender, Sentinel, and other threat protection services. It tests knowledge of tools designed for endpoint protection, threat detection, risk analytics, and cloud security.

4. Describe the Capabilities of Microsoft Compliance Solutions (25–30%)

This area introduces Microsoft Purview and related compliance tools that govern information protection, data loss prevention, insider risk, and audit readiness.

Zero Trust and the Evolving Security Landscape

Zero Trust is a cornerstone concept in Microsoft’s security architecture. It operates on the principle of never trust, always verify. This model assumes breach by default and requires that all users, devices, and services prove their legitimacy continuously before being granted access.

Unlike traditional perimeter security, Zero Trust treats every access attempt as untrusted, regardless of origin. It combines real-time risk assessment with conditional policies to create granular access controls. Implementing Zero Trust requires integration across identity verification, endpoint health, network segmentation, and behavioral analytics—areas Microsoft’s cloud platforms readily support.

Shared Responsibility Model in Cloud Security

Another vital concept is the Shared Responsibility Model. In on-premises environments, organizations are wholly responsible for securing their infrastructure. However, in the cloud, this responsibility is split between the cloud provider and the customer.

Microsoft, as the provider, ensures the security of the cloud infrastructure, including physical servers, storage, and networks. The customer is accountable for securing data, access configurations, and internal applications. SC-900 candidates must understand where Microsoft’s duties end and where theirs begin—a delineation essential for compliance and risk management.

Defense in Depth Explained

Defense in depth is a layered approach to security. Instead of relying on a single barrier to protect digital assets, organizations deploy multiple overlapping mechanisms, so that if one fails, others remain in place to stop or detect the threat.

Layers may include:

• Identity security with MFA and SSO

• Endpoint protection via Defender

• Network segmentation and firewalls

• Behavioral monitoring and automated incident response

This model reduces vulnerability to a single point of failure, making systems more resilient against complex threats.

Microsoft Entra and Identity Fundamentals

Microsoft Entra is the evolution of Microsoft’s identity and access capabilities. Central to Entra is Microsoft Entra ID, which helps organizations authenticate users, enforce access policies, and manage identity lifecycles.

Key capabilities include:

• Single Sign-On (SSO): Reduces password fatigue by enabling users to access multiple apps with one set of credentials

• Multi-Factor Authentication (MFA): Requires two or more authentication methods to improve security

• Conditional Access: Grants or blocks access based on real-time conditions such as device health, location, or sign-in behavior

• Identity Governance: Manages access reviews, entitlement management, and provisioning

• Privileged Identity Management (PIM): Controls and monitors access to sensitive roles

These features allow organizations to enforce granular access controls while ensuring a seamless user experience.

we examined the foundational elements of Microsoft’s security, compliance, and identity ecosystem. We explored concepts like Zero Trust, shared responsibility, and defense-in-depth, establishing the critical need for robust digital protection frameworks. Part 2 turns its focus to one of the most pivotal components covered in the SC-900 certification exam—Microsoft Entra, formerly known as Azure Active Directory.

Identity is the new perimeter in cloud-centric environments. When users, devices, and services are scattered across geographies and platforms, maintaining security becomes a question of validating and managing identities rather than securing perimeters. Microsoft Entra provides a comprehensive suite of identity solutions that ensure only authorized users gain access, policies are enforced dynamically, and sensitive operations are carefully monitored.

What is Microsoft Entra?

Microsoft Entra is a modern identity and access management suite developed to safeguard access to any app or resource from any location. It includes Microsoft Entra ID, Entra Permissions Management, Entra Verified ID, and other capabilities that serve various identity-related needs across organizations.

At the heart of SC-900 lies Microsoft Entra ID, which provides authentication, access control, governance, and identity protection for users in hybrid and multi-cloud environments. Its capabilities stretch far beyond traditional directory services, offering conditional access, role delegation, access reviews, and policy enforcement all under one roof.

Core Capabilities of Microsoft Entra ID

Microsoft Entra ID forms the spine of identity-driven security in Microsoft’s ecosystem. Understanding its major components is critical for passing the SC-900 exam and for real-world application.

Authentication and Single Sign-On

Authentication is the process of verifying a user’s credentials. Microsoft Entra supports multiple authentication mechanisms, including:

• Password-based sign-ins

• Certificate-based authentication

• Multi-factor authentication (MFA)

• Windows Hello for Business

• FIDO2 keys

Single Sign-On (SSO) allows users to sign in once and gain access to all permitted applications and resources without being prompted repeatedly. Entra integrates with thousands of SaaS applications, as well as on-premises solutions via Azure AD Application Proxy. SSO enhances both security and user experience by reducing credential reuse and enabling centralized monitoring.

Conditional Access Policies

Conditional Access is a policy-driven engine that evaluates signals during user sign-in and enforces decisions based on real-time risk, device status, location, and more. For example, a user logging in from an unfamiliar location may be prompted for MFA, or access to high-risk applications may be blocked altogether if the device is not compliant.

This is one of the most examined topics in SC-900, as Conditional Access embodies Microsoft’s Zero Trust approach. Candidates should understand how policies are triggered, the types of signals evaluated, and how enforcement decisions are applied.

Multi-Factor Authentication

MFA adds an extra layer of protection by requiring users to provide at least two verification factors. These can include something the user knows (password), has (phone or hardware token), or is (biometrics). Microsoft recommends enabling MFA for all users to reduce account compromise risk.

Entra supports various MFA methods, including:

• Phone call verification

• Authenticator app notifications

• SMS codes

• Hardware tokens

• Biometric solutions like Windows Hello

MFA can be applied universally or selectively via Conditional Access rules.

Identity Protection

Identity Protection leverages AI and telemetry to identify compromised accounts and risky sign-in behavior. It classifies risks into categories such as user risk, sign-in risk, and risky users. Actions can be taken automatically, such as requiring password reset or enforcing MFA.

SC-900 requires awareness of:

• Risk detection types

• Risk-based Conditional Access

• User risk remediation policies

• Integration with Security Operations Centers (SOCs)

Role-Based Access Control

Role-Based Access Control (RBAC) ensures users receive only the permissions necessary for their duties. Microsoft Entra ID includes predefined roles like Global Administrator, Security Reader, and Billing Administrator, as well as support for custom role creation.

RBAC is integral to the principle of least privilege and is used across Microsoft 365, Azure, and other integrated environments. Candidates should be familiar with the default roles and their scope.

Microsoft Entra ID Governance

Identity governance ensures users have the right access at the right time—and nothing more. Entra ID Governance includes:

• Access Reviews: Periodic checks to verify that users still need their access

• Entitlement Management: Automates access provisioning for users or groups

• Lifecycle Workflows: Automates joiner, mover, and leaver scenarios

• Privileged Identity Management (PIM): Controls and audits elevated role access

PIM allows temporary elevation of privileges, reducing the risk of standing admin access and increasing accountability through approval workflows and access logs.

Identity Federation and External Users

Organizations often need to collaborate with partners, vendors, or clients. Entra allows secure collaboration via external identities and federation.

Azure B2B Collaboration

Business-to-Business (B2B) collaboration enables external users to access resources using their own credentials. Admins can invite external users, assign roles, and apply Conditional Access policies, ensuring that external identities are managed securely.

Federation with Identity Providers

Microsoft Entra ID supports federation with identity providers like Google, Facebook, or on-premises Active Directory Federation Services (ADFS). Federation simplifies authentication and supports scenarios like single sign-on and just-in-time provisioning.

Candidates must understand the benefits and limitations of federation, particularly in hybrid identity scenarios.

Hybrid Identity Solutions

Many enterprises operate in hybrid environments where legacy systems coexist with cloud solutions. Microsoft supports several methods for hybrid identity:

• Password Hash Synchronization (PHS)

• Pass-through Authentication (PTA)

• Federation with ADFS

PHS synchronizes password hashes from on-premises AD to Microsoft Entra ID, providing a simple and secure SSO experience. PTA validates credentials directly against AD, allowing local policy enforcement. Federation provides full control over authentication, though it is more complex.

SC-900 may test candidates on the differences between these options and their use cases.

Microsoft Entra Permissions Management

Formerly CloudKnox, Permissions Management provides visibility and control over permissions across multi-cloud environments. It offers:

• Unified view of permissions across Azure, AWS, and GCP

• Risk-based insights to detect excessive or unused permissions

• Just-in-time access provisioning

While SC-900 introduces this capability at a high level, understanding the concept of over-permissioning and entitlement risk is important for governance discussions.

Microsoft Entra Verified ID

Verified ID is Microsoft’s decentralized identity solution that uses open standards like verifiable credentials. It allows organizations to issue and verify credentials digitally while maintaining user privacy and control.

Use cases include:

• Employee onboarding

• Partner verification

• Academic credential issuance

Though still evolving, Verified ID represents Microsoft’s vision for privacy-centric identity frameworks and may appear as a conceptual topic in SC-900.

Common Identity Attacks and Mitigation Strategies

SC-900 also assesses knowledge of common identity threats and how Microsoft Entra mitigates them.

Common Threats

• Credential stuffing

• Phishing

• Token theft

• Brute force attacks

• Consent phishing (malicious apps requesting elevated access)

Mitigation Techniques

• MFA deployment

• Passwordless authentication

• Conditional Access enforcement

• Risk detection and automated remediation

• Application consent governance

Candidates should recognize how various features contribute to a defense-in-depth strategy for identity.
