Election cybersecurity

The US Cybersecurity and Infrastructure Security Agency (CISA) has published its 2026 Election Infrastructure Security Plan, which describes the cyber and physical threats facing election systems and the free services CISA offers to election officials and other partners.

Homeland Security Secretary Markwayne Mullin tasked CISA with developing the plan in July. State and local election officials have primary responsibility for protecting election infrastructure, with more than 10,000 local jurisdictions managing elections. The federal government, including CISA, provides information, tools, and resources to help.

Certification rules can hold back patching

According to CISA, election software can contain vulnerabilities that need to be fixed promptly. However, the agency notes that “structural constraints within the certification ecosystem can significantly limit vendors’ ability to release patches and prevent system owners from applying them quickly.”

CISA’s assessments also show that state, local, tribal and territorial (SLTT) election offices often struggle with basic cyber hygiene and vulnerability remediation.

In addition, election infrastructure is often accessible from general enterprise networks. Attackers who compromise email systems or workstations can use that access to move laterally.

The agency names three issues, including vulnerability management limited by outdated certification regimes, inconsistent vendor transparency about vulnerabilities and patch status, and the cybersecurity immaturity of many SLTT networks that host election systems.

CISA recommends aligning patch management with certification requirements, so that security updates can be applied in real time without affecting system certification. It also recommends paper ballots and manual post-election audits.

The agency suggests that election officials encourage software providers to assign CVE identifiers to flaws, tell customers promptly if source code is leaked or stolen, report incidents to authorities, and ship a software bill of materials (SBOM) with every product.
