TMA-DEFENDER-1.10.8
Ensure 'Turn on script scanning' is set to 'Enabled'
Descripción
This policy setting allows script scanning to be turned on/off. Script scanning intercepts scripts then scans them before they are executed on the system. 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:DisableScriptScanning (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.
