As we continue our powerful momentum in securing Linux platforms, we are excited to announce the public preview of Microsoft Defender for Endpoint on Linux antivirus behavior monitoring and blocking!


 


The new preventive antivirus functionality complements our existing strong content-based capabilities with behavior monitoring and deep memory scanning. These enhancements bring immediate ability to closely monitor processes, file system activities, and process interactions within the system. The enhanced ability to correlate events and behaviors across multiple processes allows us to more generically detect and block malware based on their behavioral classification. These behavior-based signals will act as additional runtime signals for behavioral cloud-powered machine learning models and for effective runtime protection.


 


Our Linux antivirus behavior monitoring and blocking can be previewed on any Linux distribution that is currently supported by Microsoft Defender for Endpoint on Linux:



  • RHEL 7.2+,

  • CentOS Linux 7.2+

  • Ubuntu 16 LTS, or higher LTS

  • SLES 12+

  • Debian 9+

  • Oracle Linux 7.2+


 


 


Microsoft Defender for Endpoint on Linux antivirus behavior monitoring seamlessly integrates into the existing preventive experiences. Behavior monitoring details and artifacts can be explored locally using the existing Microsoft Defender for Endpoint on Linux command line interface.

Behavior monitoring alerts appear in the Microsoft Defender Security Center (as well as in the Microsoft 365 security center) alongside all other alerts and can be effectively investigated.

How to start previewing Linux antivirus behavior monitoring and blocking?


 


To get started with the Linux antivirus behavior monitoring and blocking public preview:



  • Ensure preview prerequisites are met

  • Ensure to initially evaluate this new functionality on a selected subset of your non-production Linux devices

  • Ensure cloud-delivered protection is enabled on devices enrolled into the preview by running the following command:  


$ mdatp health –field cloud_enabled # this should print “true”


 



  • Try “Do It Yourself” scenarios to see features in action. You can find “Do It Yourself” scenarios attached to this blog

  • Continue running Linux clients enrolled into evaluation as you normally would

  • Share your feedback and observations to help us improve.


 


 


We welcome your feedback and look forward to hearing from you! You can submit feedback through the Microsoft Defender Security Center or through the Microsoft 365 security center.
