Ensure 'ASR: Block executable files from running unless they meet a prevalence, age, or trusted list criterion' is set to 'Audit' or higher

보통레벨 1자동intune-defender

설명

This rule blocks executable files, such as .exe, .dll, or .scr, from launching. The recommended state for this setting is: Audit or higher. Configuring this setting to Block also conforms to the benchmark. Note: Cloud-delivered protection must be enabled to use this rule. Audit: reads the Intune PolicyManager ASR rules value (via the WinningProvider GUID) and requires the rule entry 01443614-cd74-433a-b99e-2ecdc07bfc25=1 or 01443614-cd74-433a-b99e-2ecdc07bfc25=2 (Block, or Audit for the "Audit or higher" wording).
