This feature provides continuous real-time discovery of vulnerabilities and misconfigurations on endpoints.
The process begins with automated scanning and assessment of devices to detect software vulnerabilities, missing security patches, and configuration issues. The Threat and Vulnerability Management dashboard presents a comprehensive view of the organization's exposure score, which quantifies overall risk based on discovered vulnerabilities.
Security analysts can prioritize remediation efforts using Microsoft's exposure score and device value assignments. High-value assets like domain controllers or executive workstations receive priority attention. The system correlates vulnerabilities with active threat intelligence, highlighting which weaknesses are being exploited in the wild.
Key features include the Security Recommendations page, which provides actionable guidance for addressing vulnerabilities. Each recommendation includes affected devices, potential impact, and remediation steps. Analysts can create remediation activities and track progress through integration with Microsoft Intune or other management tools.
The software inventory capability catalogs all installed applications, identifying outdated versions requiring updates. Browser extensions, certificates, and firmware are also monitored for security issues.
For remediation workflows, analysts can request exceptions for vulnerabilities that cannot be addressed due to business requirements, documenting compensating controls. The remediation tracking feature monitors patch deployment progress and validates successful vulnerability closure.
Integration with Microsoft Defender XDR allows correlation of vulnerability data with detected threats, enabling analysts to understand attack paths and prioritize based on actual exploitation attempts. Reports and dashboards facilitate communication with stakeholders about security posture improvements over time.
This systematic approach transforms reactive security into proactive risk management, significantly reducing the attack surface available to adversaries.
Identify and Remediate Devices at Risk with Vulnerability Management
Why is Vulnerability Management Important?
Vulnerability Management is crucial for security operations because it helps organizations proactively identify weaknesses in their environment before attackers can exploit them. In the SC-200 exam context, understanding this topic demonstrates your ability to reduce attack surface and protect organizational assets through systematic risk identification and remediation.
What is Vulnerability Management?
Vulnerability Management in Microsoft Defender for Endpoint is a built-in capability that provides: - Device discovery - Finding unmanaged and managed devices across your network - Vulnerability assessment - Identifying software vulnerabilities and misconfigurations - Risk-based prioritization - Ranking vulnerabilities based on threat intelligence and business context - Remediation tracking - Creating and monitoring remediation activities
How Vulnerability Management Works
1. Discovery Phase: Microsoft Defender for Endpoint sensors continuously collect data about installed software, configurations, and network exposure.
2. Assessment Phase: The collected data is analyzed against known vulnerabilities (CVEs), security misconfigurations, and exposure levels.
3. Prioritization Phase: Each vulnerability receives an exposure score and Microsoft Secure Score for Devices to help prioritize remediation efforts.
4. Remediation Phase: Security teams can create remediation requests, which integrate with Microsoft Intune or other tools for deployment.
Key Features to Remember: - Security recommendations provide actionable guidance - Exposure score ranges from 0-100 (lower is better) - Remediation activities can be tracked and assigned to IT teams - Exception handling allows for business justifications when remediation is not possible
Exam Tips: Answering Questions on Vulnerability Management
1. Know the terminology: Understand the difference between exposure score, secure score for devices, and vulnerability severity.
2. Understand the workflow: Questions often test the sequence: Discovery → Assessment → Prioritization → Remediation.
3. Remember integration points: Know that remediation can be pushed through Microsoft Intune and that tickets can be created in ServiceNow.
4. Focus on dashboards: The Threat and Vulnerability Management dashboard in Microsoft 365 Defender portal is central to this functionality.
5. Prioritization logic: Remember that prioritization considers exploit availability, threat activity, and business criticality.
6. Exception scenarios: Know when to use exceptions (compensating controls exist, third-party mitigation, low business impact).
7. Permissions required: Understand that creating remediation requests requires appropriate RBAC permissions in Microsoft 365 Defender.
8. Software inventory: Questions may ask about identifying vulnerable software versions across devices - this is found in the software inventory section.
