Ensure 'Signature Update Interval' is set to '4' or fewer, but not '0'

高レベル 1自動intune-defender

説明

This policy setting configures an interval at which to check for security intelligence updates. Security intelligence updates are the continuously updated packages that Microsoft Defender Antivirus uses to recognize, classify, and block the latest malware, spyware, unwanted software, and potentially harmful behaviors. The recommended state for this setting is: 4 or fewer, but not 0. Note: The time value is represented as the number of hours between update checks. Valid values range from 1 (every hour) to 24 (once per day). 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.
