Ensure 'Do not open files in unsafe locations in Protected View' is set to 'Disabled'

ВисокаНиво 1Аутоматскаoffice

Опис

This policy setting determines if files located in unsafe locations will open in Protected View. The recommended state for this setting is: Disabled. Note: If a specified unsafe location(s) is not configured, the "Downloaded Program Files" and "Temporary Internet Files" folders are considered unsafe locations. Rationale: Opening files located in unsafe locations that do not require Protected View could lead to malicious code executing on a user's computer or the network. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security\protectedview:disableunsafelocationsinpv (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.
