Ensure 'ASR: Block execution of potentially obfuscated scripts' is set to 'Audit' or higher

SrednjaNivo 1Automatskaintune-defender

Opis

This rule detects suspicious properties within an obfuscated script. 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 5beb7efe-fd9a-4556-801d-275e5ffc04cc=1 or 5beb7efe-fd9a-4556-801d-275e5ffc04cc=2 (Block, or Audit for the "Audit or higher" wording).
