Professor Scott Shackelford‘s opinion piece in the Christian Science Monitor, How To Make Democracy Harder To Hack, is an important read on the subject. The situation is dangerously ad hoc at the moment:
This move would help pave the way for National Institute for Standards and Technology, in collaboration with industry, to craft cybersecurity best practices to help jurisdictions across the nation navigate the often confusing choices between voting technology providers. In fact, the choice is so muddled that some cities — including Los Angeles — have developed their own systems incorporating various combinations of touch screens and paper ballots.
Shackelford’s prescription is simple:
When we flip a switch, we expect the lights to come on. When we pull a lever, or touch a screen, we expect our vote to accurately be recorded. And when we debate about the next US president, we expect that dialogue to be free of foreign entanglements. A first step in realizing these goals – and ensuring that the 2016 DNC hack, or worse, is not repeated in 2020, and 2024 – is by recognizing our democratic machinery as being at least as important as our industrial machinery.
