Election Infrastructure Security

Fair and free elections are a hallmark of American democracy. The American people’s confidence in the value of their vote is principally reliant on the security and resilience of the infrastructure that makes the Nation’s elections possible. Accordingly, an electoral process that is both secure and resilient is a vital national interest and one of the Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security Agency (CISA)’s highest priorities.

CISA is committed to working collaboratively with those on the front lines of elections—state and local governments, election officials, federal partners, and vendors—to manage risks to the Nation’s election infrastructure. CISA will remain transparent and agile in its vigorous efforts to secure America’s election infrastructure from new and evolving threats.


August 10, 2022: CISA and the Joint Cyber Defense Collaborative (JCDC) worked with the open-source community, private and public sector organizations, and JCDC alliance members to develop the Cybersecurity Toolkit to Protect Elections, a catalog of free services and tools available for state and local election officials. These tools build on existing efforts to help state and local election officials protect against ransomware, phishing, and DDoS attacks.


Every year, citizens across the United States cast their ballots for the candidates of their choice. CISA works to ensure the physical security and cybersecurity of the systems and assets that supports the Nation’s elections. Known as election infrastructure, this assembly of systems and networks includes but is not limited to:

  • Voter registration databases and associated IT systems
  • IT infrastructure and systems used to manage elections (such as the counting, auditing, and displaying of election results, and post-election reporting to certify and validate results)
  • Voting systems and associated infrastructure
  • Storage facilities for election and voting system infrastructure
  • Polling places to include early voting locations

In January 2017, DHS designated the infrastructure used to administer the Nation’s elections as critical infrastructure. This designation recognizes that the United States’ election infrastructure is of such vital importance to the American way of life that its incapacitation or destruction would have a devastating effect on the country.

CISA Election Security Resource Spotlight

Cybersecurity Toolkit to Protect Elections: CISA—through the Joint Cyber Defense Collaborative (JCDC)—has compiled a toolkit to help state and local government officials, election officials, and vendors enhance the cybersecurity and cyber resilience of U.S. election infrastructure. The toolkit provides both an election security risk profile tool to assess risk as well as tools and services focused on protecting the election infrastructure assets most commonly targeted by phishing, ransomware, and distributed denial-of-service (DDoS) attacks.

Election Security Training and Exercise Offerings: CISA offers no-cost trainings and exercise services to enhance security and resilience of election infrastructure. The trainings typically run 30-90 minutes each and available both in-person and virtually on topics such as election security best practices to build trust, insider threats, ransomware, and phishing.

Election Infrastructure Cyber Risk Assessment and Infographic are intended to assist the election community and federal partners in understanding and managing risk to critical election systems.

Election Infrastructure Security Resource Guide is a catalog of CISA’s wide range services and products (cybersecurity assessments, on-site and virtual trainings and exercises, and other resources) available to support State and local election officials.

Election Risk Profile Tool is a user-friendly assessment tool for state and local election officials to understand the range of risks they face and how to prioritize mitigation efforts.

Cyber Incident Detection and Notification Planning Guide for Election Security contains templates to help jurisdictions effectively recognize and respond to potential cyber incidents. Templates can be tailored to fit the exact needs of each jurisdiction.

Physical Security of Voting Locations and Election Facilities Guidance includes resources and four actionable steps­­—to Connect, Plan, Train, and Report—that election officials should consider to improve the physical security posture and enhance resilience of election operations in their jurisdiction.
