"We need national security standards for voting machines, and funding for states to procure machines that comply with those standards. Voting-security experts can deal with the technical details, but such machines must include a paper ballot that provides a record verifiable by voters. The simplest and most reliable way to do that is already practiced in 37 states: optical-scan paper ballots, marked by the voters, counted by computer but recountable by hand. And we need a system of pre-election and postelection security audits to increase confidence in the system."

"Nothing motivates the U.S. government like fear. Remember 2001? A small-government Republican president created the Department of Homeland Security in the wake of the Sept. 11 terrorist attacks: a rushed and ill-thought-out decision that we've been trying to fix for more than a decade. A fatal IoT disaster will similarly spur our government into action, and it's unlikely to be well-considered and thoughtful action. Our choice isn't between government involvement and no government involvement. Our choice is between smarter government involvement and stupider government involvement."

"The botnets attacking Dyn and Brian Krebs consisted largely of unsecure Internet of Things (IoT) devices — webcams, digital video recorders, routers and so on. This isn't new, either. We've already seen internet-enabled refrigerators and TVs used in DDoS botnets. But again, the scale is bigger now. In 2014, the news was hundreds of thousands of IoT devices — the Dyn attack used millions. Analysts expect the IoT to increase the number of things on the internet by a factor of 10 or more."

"Brian Krebs is a popular reporter on the cybersecurity beat. He regularly exposes cybercriminals and their tactics, and consequently is regularly a target of their ire. Last month, he wrote about an online attack-for-hire service that resulted in the arrest of the two proprietors. In the aftermath, his site was taken down by a massive DDoS attack."

"The attacks are also configured in such a way as to see what the company's total defenses are. There are many different ways to launch a DDoS attacks. The more attack vectors you employ simultaneously, the more different defenses the defender has to counter with. These companies are seeing more attacks using three or four different vectors. This means that the companies have to use everything they've got to defend themselves. They can't hold anything back. They're forced to demonstrate their defense capabilities for the attacker."

"Russia was behind the hacks into the Democratic National Committee's computer network that led to the release of thousands of internal emails just before the party's convention began, U.S. intelligence agencies have reportedly concluded."

"There have been some stories of hacks against IRS databases in the past. I think that the IRS has been hacked even more than is publicly reported, either because the government is keeping the attacks secret or because it doesn't even realize it's been attacked."
