Devices that meet defined standards for operating system version, encryption, antivirus, and other security settings can access resources seamlessly, while non-compliant devices trigger access restrictions or additional authentication requirements. The integration extends to Microsoft Defender for Endpoint, enabling real-time threat signals to influence access decisions.

Monitoring and reporting capabilities allow administrators to track policy effectiveness, user sign-in patterns, and incidents of non-compliance. By analyzing these reports, organizations can adjust policies, enforce stricter controls on high-risk access, and optimize MFA deployment to ensure minimal disruption for legitimate users.

Option B, Microsoft Purview DLP, prevents data leakage but does not enforce access policies. Option C, Microsoft Sentinel, is for threat detection and incident response. Option D, Microsoft Secure Score, provides recommendations but does not enforce MFA.

Implementing Entra Conditional Access to enforce MFA on unmanaged devices aligns directly with SC-900 learning objectives related to identity security, access management, and conditional access controls within Microsoft cloud environments. It enhances security while supporting secure access for compliant users.

Question 105

A company wants to identify potential security misconfigurations in its Microsoft 365 environment and receive actionable guidance to improve its overall security posture. Which SC-900 tool should they use?

A) Microsoft Secure Score
B) Microsoft Purview Information Protection
C) Microsoft Entra Identity Protection
D) Microsoft Sentinel

Correct Answer: A)

Explanation

Microsoft Secure Score is a security analytics tool that evaluates an organization’s Microsoft 365 environment and provides a numerical score representing the overall security posture. It identifies misconfigurations, recommends actions to remediate risks, and helps organizations prioritize improvements based on impact. Secure Score covers multiple domains including identity and access management, data protection, threat protection, device compliance, and email security.

The tool continuously scans the environment to detect security gaps and provides actionable recommendations. For example, enabling multi-factor authentication for all users, configuring anti-phishing policies in Microsoft 365, and ensuring devices meet compliance requirements can all increase the Secure Score. Each recommendation is accompanied by guidance detailing how to implement the suggested changes and the expected improvement in security posture.

Secure Score enables organizations to monitor trends over time, track progress in addressing vulnerabilities, and demonstrate compliance efforts to management or auditors. Dashboards provide a clear visualization of security health across users, devices, applications, and policies. Administrators can segment reports by department, application, or priority to focus efforts where they are most needed.

Integration with Microsoft Entra Identity Protection, Purview DLP, Microsoft Defender for Endpoint, and Microsoft Sentinel ensures a holistic approach to security. Signals from these systems feed into Secure Score, providing a unified view of risks and improvement opportunities. This allows organizations to understand the broader impact of specific misconfigurations and implement corrective measures effectively.

Option B, Microsoft Purview Information Protection, focuses on data classification and protection rather than assessing overall security posture. Option C, Microsoft Entra Identity Protection, identifies identity risks but does not evaluate general configuration issues across Microsoft 365. Option D, Microsoft Sentinel, detects threats and responds to incidents but does not provide security posture scoring or recommendations.

Using Microsoft Secure Score enables organizations to systematically assess security configurations, prioritize remediation, and implement best practices. It aligns with SC-900 objectives related to security assessment, risk management, and continuous improvement in Microsoft 365 environments.
