Ensure 'ASR: Block all Office applications from creating child processes' is set to 'Audit' or higher

MoyenneNiveau 1Automatiséeintune-defender

Description

This rule blocks Office apps from creating child processes. Office apps include Word, Excel, PowerPoint, OneNote, and Access. The recommended state for this setting is: Audit. Configuring this setting to Block also conforms to the benchmark. Audit: reads the Intune PolicyManager ASR rules value (via the WinningProvider GUID) and requires the rule entry d4f940ab-401b-4efc-aadc-ad5f3c50688a=1 or d4f940ab-401b-4efc-aadc-ad5f3c50688a=2 (Block, or Audit for the "Audit or higher" wording).
