It’s widely believed that Russian hackers were behind the recent attack on the Democratic National Committee’s e-mail servers. While the consequences of the attack for this year’s presidential election remain to be seen, it’s not hard to imagine how hackers could influence or disrupt our elections—and that could undermine our national stability and security. That’s why the government should take the advice of security experts who say it must intervene to protect the voting system from cyberthreats. As Bruce Schneier, a technologist and lecturer at Harvard’s Kennedy School of Government, argued recently in the Washington Post, the government should act quickly in the wake of the DNC hack. “If foreign governments learn they can influence our elections with impunity,” he wrote, “this opens the door to future manipulations, both document thefts and dumps like this one that we see and more subtle manipulations that we don’t see.”
