Ensure 'Allow Trusted Locations on the network' is set to 'Disabled'

HochStufe 1Automatisiertoffice

Beschreibung

This policy setting controls whether trusted locations on the network can be used. Trusted locations specified in the Trust Center are used to define file locations that are assumed to be safe by the application opening the file. The recommended state for this setting is: Disabled. Rationale: Content, code, and add-ins are allowed to load from trusted locations with a minimal amount of security, without prompting the users for permission. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security\trustedlocations:allownetworklocations (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.
