Ensure 'Do not open files from the internet zone in Protected View' is set to 'Disabled'

TinggiLevel 1Otomatisoffice

Deskripsi

This policy setting determines whether files downloaded from the Internet zone open in Protected View. The recommended state for this setting is: Disabled. Rationale: Allowing users to download files from the Internet zone to open outside of Protected View could allow malicious code to become active 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:disableinternetfilesinpv (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.
