Ensure 'Block macros from running in Office files from the internet' is set to 'Enabled'

高レベル 1自動office

説明

This policy setting allows the blocking of macros from running in Office files that come from the internet. By enabling this policy setting, macros are blocked from running, even if "Enable all macros" is selected in the Macro Settings section of the Trust Center. Users will receive a notification that macros are blocked from running. Rationale: Windows marks files downloaded from the internet using an alternate NTFS data stream. Files from untrusted sources can contain malicious payloads embedded in macros that may compromise the system on which they are run. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\access\security:blockcontentexecutionfrominternet (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 1. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
