The software's user interface does not warn the user before
					undertaking an unsafe action on behalf of that user. This makes it easier for
					attackers to trick users into inflicting damage to their
					system.Software systems should warn users that a potentially dangerous action may
						occur if the user proceeds. For example, if the user downloads a file from
						an unknown source and attempts to execute the file on their machine, then
						the application's GUI can indicate that the file is unsafe.
