Find recommendations that can improve your security posture
To improve your secure score, you have to implement the security recommendations for your environment. From the list of recommendations, you can use filters to find the recommendations that have the most impact on your score, or the ones that you were assigned to implement.
To get to the list of recommendations:
- Sign in to the Azure portal.
- In the Defender for Cloud overview, select Security posture and then select View recommendations for the environment that you want to improve.
- Go to Recommendations in the Defender for Cloud menu.
You can search for specific recommendations by name. Use the search box and filters above the list of recommendations to find specific recommendations, and look at the details of the recommendation to decide whether to remediate it, exempt resources, or disable the recommendation.
You can learn more by watching this video from the Defender for Cloud in the Field video series:
Your secure score is calculated based on the security recommendations that you have implemented. In order to increase your score and improve your security posture, you have to find recommendations with unhealthy resources and remediate those recommendations.
The list of recommendations shows the Potential score increase that you can achieve when you remediate all of the recommendations in the security control.
To find recommendations that can improve your secure score:
- In the list of recommendations, use the Potential score increase to identify the security control that contains recommendations that will increase your secure score.
- You can also use the search box and filters above the list of recommendations to find specific recommendations.
- Open a security control to see the recommendations that have unhealthy resources.
When you remediate all of the recommendations in the security control, your secure score increases by the percentage points listed for the control.
Manage the owner and ETA of recommendations that are assigned to you
Security teams can assign a recommendation to a specific person and assign a due date to drive your organization towards increased security. If you have recommendations assigned to you, you are accountable to remediate the resources affected by the recommendations to help your organization be compliant with the security policy.
Recommendations are listed as On time until their due date is passed, when they are changed to Overdue. Before the recommendation is overdue, the recommendation does not impact the secure score. The security team can also apply a grace period during which overdue recommendations continue to not impact the secure score.
To help you plan your work and report on progress, you can set an ETA for the specific resources to show when you plan to have the recommendation resolved by for those resources. You can also change the owner of the recommendation for specific resources so that the person responsible for remediation is assigned to the resource.
To change the owner of resources and set the ETA for remediation of recommendations that are assigned to you:
In the filters for list of recommendations, select Show my items only.
- The status column indicates the recommendations that are on time, overdue, or completed.
- The insights column indicates the recommendations that are in a grace period, so they currently do not impact your secure score until they become overdue.
Select an on time or overdue recommendation.
For the resources that are assigned to you, set the owner of the resource:
- Select the resources that are owned by another person, and select Change owner and set ETA.
- Select Change owner, enter the email address of the owner of the resource, and select Save. The owner of the resource gets a weekly email listing the recommendations that they are assigned to.
For resources that you own, set an ETA for remediation:
- Select resources that you plan to remediate by the same date, and select Change owner and set ETA.
- Select Change ETA and set the date by which you plan to remediate the recommendation for those resources.
- Enter a justification for the remediation by that date, and select Save.
The due date for the recommendation does not change, but the security team can see that you plan to update the resources by the specified ETA date.
Review recommendation data in Azure Resource Graph Explorer (ARG)
You can review recommendations in ARG both on the recommendations page or on an individual recommendation.
The toolbar on the recommendation details page includes an Open query button to explore the details in Azure Resource Graph (ARG), an Azure service that gives you the ability to query - across multiple subscriptions - Defender for Cloud's security posture data.
ARG is designed to provide efficient resource exploration with the ability to query at scale across your cloud environments with robust filtering, grouping, and sorting capabilities. It's a quick and efficient way to query information across Azure subscriptions programmatically or from within the Azure portal.
Using the Kusto Query Language (KQL), you can cross-reference Defender for Cloud data with other resource properties.
For example, this recommendation details page shows 15 affected resources:
When you open the underlying query, and run it, Azure Resource Graph Explorer returns the same 15 resources and their health status for this recommendation:
The Insights column of the page gives you more details for each recommendation. The options available in this section include:
|Preview recommendation||This recommendation won't affect your secure score until it's GA.|
|Fix||From within the recommendation details page, you can use 'Fix' to resolve this issue.|
|Enforce||From within the recommendation details page, you can automatically deploy a policy to fix this issue whenever someone creates a non-compliant resource.|
|Deny||From within the recommendation details page, you can prevent new resources from being created with this issue.|
Recommendations that aren't included in the calculations of your secure score, should still be remediated wherever possible, so that when the period ends they'll contribute towards your score instead of against it.
Download recommendations in a CSV report
Recommendations can be downloaded to a CSV report from the Recommendations page.
To download a CSV report of your recommendations:
Sign in to the Azure portal.
Navigate to Microsoft Defender for Cloud > Recommendations.
Select Download CSV report.
You'll know the report is being prepared by the pop-up.
When the report is ready, you'll be notified by a second pop-up.
