This policy setting allows you to configure behavior monitoring for Windows Defender Antivirus. The recommended state for this setting is: Enabled. Rationale: When running an antivirus solution such as Windows Defender Antivirus, it is important to ensure that it is configured to heuristically monitor in real-time for suspicious and known malicious activity.
To establish the recommended configuration via GP, set the following UI path to Enabled: Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Defender Antivirus\Real-Time Protection\Turn on behavior monitoring Note: This Group Policy path may not exist by default. It is provided by the Group Policy template WindowsDefender.admx/adml that is included with the Microsoft Windows 8.1 & Server 2012 R2 Administrative Templates (or newer). Impact: None - this is the default configuration. Default Value: Enabled. (Behavior monitoring will be enabled.) References: CCE-38389-3
