Ensure 'Prevent bypassing of Microsoft Defender SmartScreen warnings about downloads' is set to 'Enabled'

HochStufe 1Automatisiertedge

Beschreibung

This policy setting controls whether users may override Microsoft Defender SmartScreen warnings regarding downloads that are unverified. The recommended state for this setting is: Enabled. Rationale: Smartscreen checks downloads and verifies whether they are deemed safe or not. Only allowing verified downloads greatly reduces risk of a download containing a virus, spyware, or other unwanted software. 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\Edge:PreventSmartScreenPromptOverrideForFiles (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.
