Ensure 'Configure Attack Surface Reduction rules' is set to 'Enabled'

HochStufe 1Automatisiertdefender

Beschreibung

This policy setting controls the state for the Attack Surface Reduction (ASR) rules. The recommended state for this setting is: Enabled. Rationale: Attack surface reduction helps prevent actions and apps that are typically used by exploit-seeking malware to infect machines. 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\Windows Defender Exploit Guard\ASR:ExploitGuard_ASR_Rules (REG_DWORD); compliant when it is 1. Remediation writes 1 locally; in a domain set it through the ADMX so Group Policy does not revert it.
