I prefer leaving things to the market as much as possible.

Everyone is a proponent of strong encryption.

Cyber terrorism could also become more attractive as the real and virtual worlds become more closely coupled, with automobiles, appliances, and other devices attached to the Internet.

I don't have a particular recommendation other than that we base decisions on as much hard data as possible. We need to carefully look at all the options and all their ramifications in making our decisions.

Systems are complex, so controlling an attack and achieving a desired level of damage may be harder than using physical weapons.

Generally I'm against regulation.

If we take as given that critical infrastructures are vulnerable to a cyber terrorist attack, then the question becomes whether there are actors with the capability and motivation to carry out such an operation.
