Microsoft announced today that Microsoft Defender for Endpoint’s detection and response (EDR) capabilities are now generally available on Linux servers. EDR capabilities allow admins and security teams to spot attacks targeting or involving Linux servers in their environments almost in real-time with the help of alerts automatically aggregated as incidents based on attacker techniques and attribution. The new capabilities were released in public preview in November 2020, and it was made generally available in June 2020. It adds to the already existing preventative antivirus capabilities and the centralized reporting features available to admins via the Microsoft Defender Security Center.
