Опис

This rule prevents an application from writing a vulnerable signed driver to disk. The recommended state for this setting is: Block. Note: The Block abuse of exploited vulnerable signed drivers setting does not block a driver that already exists on the system from being loaded. Audit: reads the Intune PolicyManager ASR rules value (via the WinningProvider GUID) and requires the rule entry 56a863a9-875e-4185-98a7-b882c64b5ce5=1 (Block).
