Microsoft Defender for servers

Overview

Microsoft Defender for Server is one of the advanced security features of Microsoft Defender for Cloud and enables threat detection and advanced defenses definition for Windows and Linux servers, regardless of whether they are running within Microsoft Azure, On-Premises or in a multi-cloud environment.

Solution and benefits

The solution collects data for the systems:

  • Windows: by monitoring servers with Windows operating system, Microsoft Defender for Cloud presents alerts and suggestions to deal with any anomalies found;
  • Linux: Microsoft Defender for Cloud collects audit records from Linux machines, using auditd, one of the most common Linux auditing frameworks.
  • For hybrid and multi-cloud scenarios, Microsoft Defender for Cloud integrates with Azure Arc, so that “non-Azure” machines are seen as Azure resources.

These are some of the benefits that can be obtained thanks to Microsoft Defender for Server:

  • Integrated license for Microsoft Defender for Endpoints: Microsoft Defender for Server includes Microsoft Defender for Endpoints.
  • Tools for identifying and managing vulnerabilities and configuration errors in real time;
  • JIT (Just-in-Time) access to Virtual Machines (VMs) allows you to provide controlled access to the VMs themselves;
  • File Integrity Monitoring (FIM) – Analyzes, for example, operating system files and logs, to check for changes that could indicate an attack.
