Today, we are excited to announce the public preview of endpoint detection and response (EDR) capabilities in Microsoft Defender for Endpoint on Linux servers.


 


With the new Linux EDR capabilities, Defender for Endpoint customers will have the ability to detect advanced attacks that involve Linux servers, utilize rich experiences, and quickly remediate threats. This builds on the existing preventative antivirus capabilities and centralized reporting available via the Microsoft Defender Security Center.

  1. Verify that the onboarded Linux server appears in Microsoft Defender Security Center. If this is the first onboarding of the machine, it can take up to 20 minutes until it appears. 

  2. Download and extract the script file from here aka.ms/LinuxDIY to an onboarded Linux server and run the following command: “./mde_linux_edr_diy.sh”

  3. After a few minutes, should be raised in Microsoft Defender Security Center.

  4. Look at the alert details, machine timeline, and perform your typical investigation steps.
