Your dashboard has dozens of recommendations, but the team can only work on a few today. Which ones should come first? A useful answer considers exposure, business impact, and the actual remediation path. We'll turn a recommendation into an owned change with evidence that it improved the intended resource.

Security scores summarize aspects of assessed posture. They are not a guarantee against compromise or a substitute for understanding a finding. Review what a recommendation checks and which resources are affected. Some changes may have dependencies or operational consequences. A smaller score improvement can still address a more important risk in your environment.

In a fictional example, a storage-related recommendation affects a production application. Confirm the resource and the insecure condition before changing it. Read the remediation guidance and identify dependencies. Ask whether the application needs a safer alternative access path. The goal is to remove unnecessary exposure without making an unplanned service outage.

Assign an owner, a change window where needed, and a verification method. Apply the authorized change and test the legitimate workload. Then check whether the assessment reflects the corrected state. Record the timing, since reassessment may not be immediate. A completed change ticket is useful, but the resource state and service behavior are the evidence.

Sometimes a recommendation cannot be implemented immediately. An exception should have a reason, an accountable owner, compensating controls where appropriate, and a review date. Exempting or dismissing a finding does not remove the underlying risk. Keep reporting clear enough that an exception cannot be mistaken for a verified remediation.

A team's score increases after several findings are exempted. Does that establish that the underlying exposures were fixed? Pause and distinguish the reporting state from the resource state.

No. You need evidence of the resource's actual condition and a clear record of any exception. Use the score as one signal while tracking ownership, impact, and verification. For practice, write a remediation record with the finding, planned change, success check, and review date. That record is more actionable than a number alone.

Course outlineLesson 16 of 18

Security recommendations and Secure Score form the core of Defender for Cloud posture management. This lesson covers recommendation categories, remediation workflows, exemptions, and Secure Score calculation for the SC-200 exam.

Security Recommendations

Defender for Cloud continuously assesses resources against the Microsoft Cloud Security Benchmark (MCSB) and other enabled standards. Each finding generates a recommendation with:

  • Severity: High, Medium, Low
  • Resource health: Healthy, Unhealthy, Not applicable
  • Freshness interval: How often the assessment runs
  • Remediation steps: Manual instructions or automated "Fix" button
  • Related policy: The Azure Policy definition driving the assessment

Microsoft Cloud Security Benchmark (MCSB)

MCSB is the default security standard applied to all subscriptions. It organizes recommendations into control families:

Control FamilyExamples
Network SecurityNSG rules, private endpoints, DDoS protection
Identity ManagementMFA enforcement, conditional access, PIM
Privileged AccessJIT VM access, admin account protection
Data ProtectionEncryption at rest, TDE, key rotation
Logging and MonitoringDiagnostic settings, log analytics, alerts
Backup and RecoveryVM backup, database backup policies
Endpoint SecurityEndpoint protection, vulnerability assessment
Exam tip: MCSB is enabled by default for all Azure subscriptions with Defender for Cloud. You do not need to enable it manually.

Secure Score

Secure Score represents your overall security posture as a percentage. It is calculated based on:

  • Maximum score: Total possible points across all recommendations
  • Current score: Points earned from healthy (compliant) resources
  • Percentage: Current / Maximum * 100

Each recommendation contributes points to a security control. Controls are weighted by impact:

Secure Score = (Sum of healthy resource points across all controls) / (Sum of maximum points across all controls) * 100
Key principles:
  • Fixing all resources for a single recommendation earns the full points for that control
  • Partially fixing resources within a control earns partial credit
  • Controls with more critical recommendations are weighted higher
Exam tip: You only earn points for a control when ALL recommendations within that control are fully resolved, or you earn partial credit per healthy resource. The exam may ask how fixing a specific recommendation affects the score.

Remediation Workflows

Three approaches to remediation: 1. Manual remediation:

  • Follow the step-by-step instructions in the recommendation
  • Best for complex changes requiring planning
2. Quick Fix (automated):
  • Click "Fix" on the recommendation to apply a pre-built remediation
  • Uses ARM templates or Azure Policy remediation tasks
  • Review the fix logic before applying
3. Governance rules:
  • Assign a recommendation owner with a remediation deadline
  • Track progress through the governance dashboard
  • Send email notifications for upcoming deadlines

Exemptions

When a recommendation does not apply to your environment, create an exemption:

  • Waiver: Accepted risk. The recommendation is valid but you accept the risk
  • Mitigated: You have an alternative control in place that addresses the risk

Exemptions remove the recommendation from your Secure Score calculation. They require a justification and can be time-limited. Exam tip: Exemptions with the "Mitigated" reason indicate an alternative control is in place. "Waiver" means the risk is accepted without alternative mitigation.

Custom Recommendations

Create custom recommendations using Azure Policy:

  1. Define or assign an Azure Policy (built-in or custom)
  2. Map the policy to a custom security standard in Defender for Cloud
  3. The policy evaluation results appear as recommendations

Custom recommendations appear alongside built-in ones and contribute to the Secure Score when added to a standard.

Recommendation Filters

Filter recommendations by:

  • Environment (Azure, AWS, GCP)
  • Severity (High, Medium, Low)
  • Resource type
  • Security control
  • Compliance standard
  • Freshness (stale vs. current assessments)
Exam Focus Points
  • ✓Microsoft Cloud Security Benchmark (MCSB) is enabled by default for all Azure subscriptions.
  • ✓Secure Score is calculated as healthy resource points divided by maximum possible points.
  • ✓Exemptions remove recommendations from Secure Score. "Waiver" accepts risk; "Mitigated" indicates an alternative control.
  • ✓Quick Fix applies pre-built remediation using ARM templates or Azure Policy remediation tasks.
  • ✓Governance rules assign owners with deadlines for recommendation remediation.
  • ✓Custom recommendations use Azure Policy definitions mapped to custom security standards.
Knowledge Check

1. A recommendation to enable disk encryption does not apply because the organization uses a third-party encryption solution. Which exemption reason should they use?

2. Which security standard is enabled by default for all Azure subscriptions in Defender for Cloud?

3. An organization fixes 5 of 10 unhealthy resources for a security recommendation. How does this affect the Secure Score?
