This is an interesting notion, but I wonder if there would really be support for such laws.

In Canada, you can't even call yourself an "Engineer" if you aren't an accredited P.Eng license holder. And a P.Eng who signs off on safety related designs that aren't safe (or signs of pretending to be a P.Eng) can actually go to jail. And that's something I fully support.

But would people support similar laws for information security? I would, but would enough people that the government would pass such rules? Hard to say.
