Ensure 'Turn on behavior monitoring' is set to 'Enabled'

ÉlevéeNiveau 1Automatiséedefender

Description

This policy setting allows you to configure behavior monitoring for Microsoft Defender Antivirus. The recommended state for this setting is: Enabled. Rationale: When running an antivirus solution such as Microsoft Defender Antivirus, it is important to ensure that it is configured to heuristically monitor in real-time for suspicious and known malicious activity. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Real-TimeProtection:DisableBehaviorMonitoring (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.
