National: CISA and VotingWorks release open source post-election auditing tool | Catalin Cimpanu/ZDNet
The US Cybersecurity and Infrastructure Security Agency (CISA) and VotingWorks, a non-partisan, non-profit organization, have open-sourced today a tool for the post-election auditing process. Developed by VotingWorks and named Arlo, the tool is available on GitHub. It’s a web-based app designed specifically for the US election process where votes are tallied electronically using software or special machines. To safeguard the election process against hacked or faulty voting systems, the US government mandates that all counted votes go through a post-election audit to verify the results, in a process called a Risk-Limiting Audit (RLA). Arlo is designed to automate this auditing process by automatically selecting random voter ballots for the RLA process, providing auditors with the information they need to find those ballots in storage, helping officials compare audited votes to tabulated votes, and providing monitoring & reporting capabilities so that election officials and public observers can follow the audit’s progress and outcome. “The tool supports numerous types of post-election audits across various types of voting systems including all major vendors,” CISA said in a press release today. CISA did not develop Arlo — created by VotingWorks on its own — but the agency has adopted the tool and is currently working on convincing state election officials to deploy it before next year’s presidential election.
