Fact check: What cybersecurity measures protected voting machines during the 2024 election?

Checked on June 10, 2025

1. Summary of the results

Multiple layers of cybersecurity measures were implemented during the 2024 election, including:

  • Paper confirmation slips and authentication processes [1]
  • Isolation of critical systems from the internet
  • Secured storage devices for data transfer
  • Access logs and private networks
  • Physical security measures like tamper-evident seals [2]
  • Approximately 98% of ballots had a paper record for verification [2]

2. Missing context/alternative viewpoints

Several critical security concerns emerged that the question doesn't address:

  • Unauthorized access to voting system software occurred in multiple states including Georgia, Michigan, Pennsylvania, Ohio, Nevada, and Colorado by allies of former President Trump [3]
  • These breaches affected equipment from companies that count over 70% of votes nationwide [3]
  • While vulnerabilities exist, there have been no confirmed cases of systematic vote switching [1]

Important institutional context:

CISA (Cybersecurity and Infrastructure Security Agency) has been actively involved in election security since 2017 by:

  • Designating election infrastructure as critical infrastructure
  • Creating a cyber defense toolkit
  • Offering free services to state/local governments
  • Maintaining an Elections Infrastructure Information Sharing and Analysis Center (EI-ISAC) [4]

3. Potential misinformation/bias in the original statement

The question assumes cybersecurity measures were effective and comprehensive, while evidence suggests significant vulnerabilities:

  • Unauthorized access could have allowed malicious actors to:
  • Identify system vulnerabilities
  • Practice election interference techniques
  • Potentially fabricate evidence of tampering [3]

Who benefits from different narratives:

  • Election equipment manufacturers benefit from emphasizing their security measures
  • Political actors might benefit from either:
  • Highlighting vulnerabilities to question election integrity
  • Emphasizing security measures to maintain public trust
  • Federal agencies like CISA benefit from demonstrating their protective role in election security [4]
