Ensure 'ActiveX Control Initialization' is set to 'Enabled: 6'

AltaNivel 1Automatizadaoffice

Descripción

This policy setting specifies the Microsoft ActiveX® initialization security level for all Microsoft Office applications. The recommended state for this setting is: Enabled: 6 Rationale: Attackers can use ActiveX controls that include malicious code to attack a computer. In addition, malicious code can be used to compromise an ActiveX control and attack a computer. To indicate the safety of an ActiveX control, developers can denote them as Safe For Initialization (SFI). User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\common\security:uficontrols (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 6. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
