We brought together a panel of more than 100 cybersecurity leaders from across government, the private sector, academia and the research community for a new feature called The Network - an ongoing, informal survey. Our first survey revealed deep concerns that states aren't prepared to defend themselves against the types of cyberattacks that disrupted the 2016 presidential election. Several experts said that state voter registration databases are particularly vulnerable - and make an appealing target for attackers who want to sow confusion and undermine confidence in the voting process. "The voting machines themselves are only part of the story," said Matt Blaze, a cryptographer and computer science professor. "The 'back end' systems, used by states and counties for voter registration and counting ballots, are equally critical to election security, and these systems are often connected, directly or indirectly, to the Internet." Jay Kaplan, co-founder of the cybersecurity firm Synack, notes a bright spot: The Election Assistance Commission has a national voting system certification program to independently verify that a voting system meets security requirements. "However, testing for this certification is completely optional," said Kaplan. "States can set their own standards for voting systems. As such, some states are significantly more buttoned up than others. The reality is states are understaffed, underfunded, and are too heavily reliant on election-system vendors securing their own systems."
