Standardizing voter registration processes, voting machines and vote tabulation is the key to eliminating most vulnerabilities plaguing U.S. elections, according to several cybersecurity experts. These standardizations would embed security, enable backups and eliminate many backdoors through which hackers and vote fraudsters currently can warp the results of an election. While voting is administered at the state and local levels, these remedies would need to be applied nationwide. The current web of diverse processes may increase the difficulty for wide-scale election tampering, but they also ensure that achieving security is too broad a challenge for any single remedy to be applied. This diversity also virtually ensures that some location will have a vulnerability that, if exploited effectively, could cast doubt on a nationwide election result. … Auditing capabilities are important, says Ron Bandes, network security analyst in the CERT division of the Software Engineering Institute of Carnegie Mellon University. He also is president of VoteAllegheny, a nonpartisan election integrity organization.
