Election system security sits at the intersection of two disciplines that don’t always speak the same language: election administration and information security. This section gathers resources and discussion on the technical side of that intersection — how voting equipment is built, tested, and secured, and what independent security researchers have found when they’ve been given the opportunity to examine these systems closely.
Topics we cover here include the security architecture of different voting technologies (from hand-counted paper to optical scan to direct-recording electronic systems), the certification and testing processes equipment must pass before deployment, the role of independent “logic and accuracy” testing before each election, and how post-election audits function as a backstop against both technical failure and deliberate tampering.
None of this material assumes the worst about any specific vendor or jurisdiction. It’s offered in the spirit that security is best served by open discussion of known vulnerabilities and defenses, not by treating the subject as too sensitive to examine in public.
