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.

Fact Sheets and Flyers

CISA Insights: Chain of Custody and Critical Infrastructure Systems: This CISA Insights provides an overview of what chain of custody is, highlights the potential impacts and risks resulting from a broken chain of custody, and offers critical infrastructure owners and operators an initial framework with five actionable steps for securing chain of custody for their physical and digital assets. It also includes examples of physical and digital chain of custody for the election infrastructure subsector, chemical sector, and more.

Domain-Based Message Authentication, Reporting and Conformance (DMARC): A fact sheet on the importance of DMARC (an email authentication policy that protects against fake emails disguised to look like legitimate emails from trusted sources), instructions for handling a fraudulent email, and how to adopt DMARC.

Hyper Text Transfer Protocol Secure (HTTPS): A fact sheet on HTTPS—used to encrypt and secure information transmitted between a user's web browser and a website. Encryption is especially important on webpages that collect information through forms or requires a user to login, such as online voter registration.

Multi-Factor Authentication (MFA): A fact sheet on using MFA—a layered approach to securing data and applications where a system requires a user to present two or more credentials at login to verify a user's identify. MFA reduces the risk of adversaries gaining access to the targeted physical space, computing device, network, or database.

Ransomware: A fact sheet that includes best practices to protect your systems and data against ransomware, planning for a ransomware incident, recovering from a ransomware attack, and CISA services and support.

Sign Up for a .gov Domain: Information for Election Officials: This fact sheet explains the importance for election officials to sign up for a .gov domain. Election officials continue to combat false and misleading election information, making it increasingly difficult to identify trusted sources of information. As the Agency that oversees the .gov top-level domain, CISA provides .gov domains for election offices to help the public quickly identify accurate election information.
