Ensure 'Remote Encryption Protection Aggressiveness' is set to 'Medium' or higher

高レベル 2自動intune-defender

説明

This policy setting configures how aggressively Remote Encryption Prevention Protection blocks malicious IP addresses. The recommended state for this setting is: Medium: Use cloud aggregation and block when confidence level is above 99% or higher. Configuring this setting to High: Use cloud intel and context, and block when confidence level is above 90% also conforms to the benchmark. Note: As of the publication of this Benchmark, the setting configuration state in Intune is the sentence above after The recommended state for this setting is: and not Medium or higher as the title states. This was done to keep title length to a minimum. Audit: reads the registry value(s) behind this Defender policy (HKLM\SOFTWARE\Policies\Microsoft\Windows Defender) and prints compliant only when each satisfies the benchmark value. Policy delivered by Intune only appears here once it has been applied to the device.
