4. What solutions have been proposed for this problem? Do you think they will be effective?

Why or why not? In July 2010, reports surfaced about a Stuxnet worm that had been targeting Iran’s nuclear facilities. In November of that year, Iran’s President Mahmoud Ahmadinejad publicly acknowledged that malicious software had infected the Iranian nuclear facilities and disrupted the nuclear program by disabling the facilities’ centrifuges. Stuxnet had earned its place in history as the first visible example of industrial cyberwarfare.

To date, Stuxnet is the most sophisticated cyberweapon ever deployed. Stuxnet’s mission was to activate only computers that ran Supervisory Control and Data Acquisition (SCADA) software used in Siemens centrifuges to enrich uranium. The Windows-based worm had a “dual warhead.” One part was designed to lay dormant for long periods, then speed up Iran’s nuclear centrifuges so that they spun wildly out of control. Another secretly recorded what normal operations at the nuclear plant looked like and then played those recordings back to plant operators so it would appear that the centrifuges were operating normally when they were actually tearing themselves apart
