Colorado: How Colorado voting became a cybersecurity leader long before Russians tried to hack it | TechRepublic
Colorado was one of 21 states targeted by Russian operatives during the 2016 election. But unlike many others, the state has spent years implementing top-tier cybersecurity measures and audits to prevent hackers from entering its systems and interfering with the election process. Colorado receives top marks in the three most important election security categories, according to a February report from the left-leaning Center for American Progress comparing the election security of all 50 states:
Adhering to minimum cybersecurity standards for voter registration systems
Carrying out elections with paper ballots
Conducting robust post-election audits
… In 2017, Colorado became the first state to carry out mandatory risk-limiting post-election audits, which are widely considered the gold standard, according to the Center for American Progress. Risk-limiting audits involve manually checking a sample of ballots, and providing statistical evidence that the election outcome is correct. They have a high probability of correcting a wrong outcome, according to the US Election Assistance Commission. A risk-limiting audit could lead to a full manual recount if there is not enough evidence to prove that the reported outcome is correct, the commission stated.
