Ensure 'Require that application add-ins are signed by Trusted Publisher' is set to 'Enabled'

HochStufe 1Automatisiertoffice

Beschreibung

This policy setting controls whether add-ins for the specified Office application must be digitally signed by a trusted publisher. The recommended state for this setting is: Enabled. Rationale: By default, Office applications do not check the digital signature on application add-ins before opening them. Disabling or not configuring this setting may allow an application to load a dangerous add-in. As a result, malicious code could 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:requireaddinsig (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.
