ActiveX controls can adversely affect a computer directly. 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). SFI indicates that a control is safe to open and run, and that it is not capable of causing a problem for any computer, regardless of whether it has persisted data values or not. If a control is not marked SFI, it is possible that the control could adversely affect a computer--or it could mean that the developers did not test the control in all situations and are not sure whether it might be compromised in the future. If you enable this policy setting, you can set the ActiveX security level to a number between 1 and 6. These security levels are as follows: - -1. Regardless of how the control is marked, load it and use the persisted values (if any). This setting does not prompt the user. -2. If SFI, load the control in safe mode and use persisted values (if any). If not SFI, load in unsafe mode with persisted values (if any), or use the default (first-time initialization) settings. This level is similar to the default configuration, but does not prompt the user. +1. Regardless of how the control is marked, load it and use the persisted values (if any).

Important: Some ActiveX controls do not respect the safe mode registry setting, and therefore might load persisted data even though you configure this setting to instruct the control to use safe mode.

If any of them are remote locations and you do not allow remote locations via this policy setting, those policy keys that point to remote locations will be ignored on client computers. Disabling this policy setting does not delete any network locations from the Trusted Locations list, but causes disruption for users who add network locations to the Trusted Locations list. Users are also prevented from adding new network locations to the Trusted Locations list in the Trust Center.

Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. +acceptedCanonical Ubuntu 18.04 LTS Security Technical Implementation GuideThis Security Technical Implementation Guide is published as a tool to improve the security of Department of Defense (DoD) information systems.
