This is John Barbare and I am a Sr Customer Engineer at Microsoft focusing on all things in the Cybersecurity space. In this blog I will walk you through the steps of navigating through the Microsoft Defender Advanced Threat Protection (ATP) portal to see how prone your organization is from an attack or breach from an application perspectiveAfter viewing the different sections, we will see how to remediate and decrease your overall attack surface using Microsoft Endpoint Manager (MEM) so your organization’s security posture will be at a level that your CIO/CISO will be comfortable withWithout further hesitation, let’s get started and jump right into all things Microsoft Defender ATP and MEM. 


Licensing requirements 


Microsoft Defender ATP licensing requirements: 

  • Windows 10 Enterprise E5 
  • Windows 10 Education A5 
  • Microsoft 365 E5 (M365 E5) which includes Windows 10 Enterprise E5 
  • Microsoft 365 E5 Security 
  • Microsoft 365 A5 (M365 A5) 

More information can be found here. 


Microsoft Defender ATP for US Government Community Cloud High (GCC High) customers, built in the US Azure Government environment, uses the same underlying technologies as Microsoft Defender ATP in Azure Commercial. This offering is currently available to US Office 365 GCC High customers and is based on the same prevention, detection, investigation, and remediation as the commercial version. 


If you currently use Configuration Manager, you also get Microsoft Intune/MEM to co-manage your Windows devices. For other platforms, such as iOS/iPadOS and Android, then you will need a separate license. In most scenarios, Microsoft 365 may be the best option, as it gives you MEM and Office 365. For more information, see Microsoft 365. More information on licensing and changes with licensing for co-management in MEM can be found here. 


Prerequisites to use MEM with Microsoft Defender ATP 


Deploy a device configuration policy with a profile type of Microsoft Defender ATP (Windows 10 Desktop) to devices that will have risk assessed by ATP. 


Login into Security Center – Microsoft Defender ATP Portal 


Navigate to Microsoft Defender Security Center and login with your credentials at 


Navigate to Settings and then Advanced features. Make sure Microsoft Secure Score and Microsoft Intune connection are turned to on.

 Threat and Vulnerability Management 

Go to the Threat & Vulnerability Management tab on the left and then click on Dashboard. This dashboard gives your organization an overall picture of the entire security posture broken down into three main categories.  


  1. Exposure Score - Reflects how vulnerable your organization is to cybersecurity threats. Depending on the level of the score it will show you if you are less or more vulnerable to attacks. Several factors affect your organization's exposure score: weaknesses discovered in your devices, likelihood of your devices to be breached, value of the devices to your organization, and relevant alerts discovered with your devices. The goal is to lower the exposure score of your organization to be more secure.  
  2. Secure Score for Devices  Reflects how your endpoints are more resilient from cybersecurity threat attacks. It reflects the collective security configuration state of your devices across five categories which include ApplicationOperating systemNetworkAccounts and Security controls. You can select any of the corresponding colored horizontal bars and it will take you to the Security recommendation page. The goal is to remediate the related security configuration issues to increase your score for devices. 
  3. Device exposure distribution - Reflects how many devices are exposed based on their exposure level. You can select a slice in the doughnut chart to go to the Devices list page and view the affected device names, exposure level, risk level, and other details such as domain, operating system platform, its health state, when it was last seen, and any tags that are assigned.

 The column on the far right, Top security recommendationsshows the top five software that is impacting your organization from a threat standpoint. They are sorted and prioritized based on your organization's risk exposure and the urgency that it requires. This includes both Microsoft software and third-party installations across your entire organization. 


Active Threats and Vulnerabilities 


Next, we will click on the Software inventory tab which is located three tabs below the Dashboard. From here, you will see the complete list of every piece of software that is installed in your organization. Click on the Weaknesses tab twice to rank the number of software weaknesses in order from greatest to least. The number of weaknesses corresponds to the number of Common Vulnerabilities and Exposures (CVE). CVE is a list of entries that each contain an identification number, a description, and a minimum of at least one public reference for known cybersecurity vulnerabilities. Under the Threats column, you can click on any icon that is displayed as a red bug to give you threat insights into a likely breach scenario in your environment. The Exposed devices column displays the total number of exposed devices the piece of vulnerable software is installed on. The Impact displays graph over time with a corresponding score. The lower exposure score means the devices are less vulnerable from exploitation.

The next step, we will perform a full remediation based off the security recommendations in the previous section. MEM will be used to update the software which will be selected in the next steps. 


Select the Security recommendations tab and then click on the piece of software you want to remediate. We will be updating Microsoft Edge Chromium for this task and we will select it. 


A fly out screen will display and on the bottom you can expand the number of exposed and installed devices to see the full list. Next, we will click on the Remediation options button.

Notice for the description it states that submitting a remediation request creates an activity item, which can be used to monitor the remediation progress of this recommendation. It will not apply any changes to devices. Mitigation actions, on the other hand, will be applied immediately. Select the following items in the picture below and click submit

Navigate to MEM and login with your credentials at Click on Endpoint Security and then Security Tasks. 


You can see the task that was created and it is referred to as a “Security Task.

When selecting the task, which is pending for the Microsoft Edge Chromium update, you will see the following information for remediation. If an app is not a managed app, MEM can only provide detailed text instructions as seen in the below image. If the app is managedMEM will provide instructions to download an updated version and provide a link to open the deployment for the app so that the updated files can be added to the deployment. The admin then remediates the task based on the guidance provided. The guidance varies depending on the type of remediation that's needed. When available, remediation guidance includes links that open relevant panes for configurations in MEM. After following the steps for the remediation to update the appclick accept.

Once accepted, it will sync back over to Microsoft Defender ATP and the Ticket status column will be updated with Completed (Intune).

Select the Completed (Intune) name and a fly out window will appear. Go ahead and select Mark as completed and the remediation activity will be resolved. This will update the secure score along with other metrics and security recommendations.

Thanks for taking the time to read this blog and I hope you had fun reading how to find current CVEssoftware threats, possible breach activity, secure score, using the dashboard under Threat and Vulnerability Management, and to remediate and update apps using MEM. Once you start using MEM and Microsoft Defender ATP to create remediation tickets and update your apps you will find it more productive while also reducing your overall attack surface. On a final note, Gartner just announced Microsoft as a Leader in its 2020 Magic Quadrant for Unified Endpoint Management. Read the article here
