Election Security Resource Library

Securing election infrastructure from new and evolving threats is a vital national interest that requires a whole-of-society approach. This library provides state and local governments, election officials, campaigns, the vendor community, and voters with voluntary tools to secure election-related assets, facilities, networks and systems from cyber and physical risks.

In addition, COVID-19 resources were developed by the Election Infrastructure Subsector’s Government Coordinating Council (GCC) and Sector Coordinating Council (SCC) Joint COVID-19 Working Group to provide voluntary tools for state and local election officials to assess risk, secure their systems, and respond to any cyber-related incidents involving their elections systems.

Beyond these resources, CISA provides voluntary and free cybersecurity assessments, training programs, and other infrastructure security assistance.

    Last Mile Products

    Thousands of local jurisdictions, vendors, and political campaigns make up the majority of the U.S. elections stakeholder community, and together present the biggest opportunities and vulnerabilities for election security. The independence and resource disparity among these entities creates significant challenges to information sharing and implementation of best practices.

    CISA’s Last Mile products are scalable, customizable tools that local stakeholders can use immediately to improve security and awareness of additional services available. These products (such as Election Security Planning Snapshot, Election Emergency Response Guides, Election Safeguards, and other templates) aim to strengthen the relationships among national, state, and local partners, which are essential for effective information sharing and continual engagement on critical election security issues.
