Explore Our Microsoft Cloud Security Training →

Microsoft Defender for Cloud (MDC) assesses your cloud environment’s security posture using a score called the Secure Score. This blog post provides a step-by-step guide on improving your MDC Secure Score by prioritizing high-impact, low-effort recommendations and tracking remediation progress with Defender for Cloud.

How is Microsoft Defender for Cloud Secure Score Calculated?

The Secure Score is based on a set of recommendations that align with the Shared Responsibility Model. It evaluates your cloud environment’s adherence to best practices in areas such as identity, data protection, networking, and compliance.

Identifying Highest-Impact Recommendations

Start by focusing on recommendations with the highest potential impact. These typically involve implementing Multi-Factor Authentication (MFA), Just-In-Time VM access, and disk encryption.

Remediating Common Recommendations

• Multi-Factor Authentication: Enable MFA for users and administrators to add an extra layer of security to sign-ins.
• Just-In-Time VM Access: Implement JIT access policies to restrict unnecessary network traffic and reduce the attack surface.
• Disk Encryption: Configure encryption for virtual machines, managed disks, and files stored in Azure Storage accounts.

Using Defender for Cloud to Track Remediation Progress

Defender for Cloud offers remediation guides to help you implement recommendations more efficiently. You can also delegate tasks to resource owners and track weekly progress to stay on top of your Secure Score improvement.

Setting Secure Score Improvement Targets

Set targets for your team based on the current Secure Score and desired level of security. Regularly review your progress and adjust targets as needed to ensure continuous improvement.

Conclusion

By focusing on high-impact, low-effort recommendations and using Defender for Cloud for efficient remediation, you can improve your Azure Security Center Secure Score and enhance the security of your cloud environment.
