Ensure 'Turn off Protected View for attachments opened from Outlook' is set to 'Disabled'

CaoCấp 1Tự độngoffice

Mô tả

This policy setting determines if Excel files in Outlook attachments open in Protected View. The recommended state for this setting is: Disabled. Rationale: Email is a common vector for spreading files containing malicious code. Disabling Protected View changes this default behavior and could allow malicious code to execute on a user's computer or across the network. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security\protectedview:disableattachmentsinpv (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 0. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
