The Essential Guide to Election Security

Center for Internet Security (2025)

Developed by the Center for Internet Security (CIS), this comprehensive guide serves as a first-stop resource for election officials on best practices in election security. Accounting for the wide range of technical capacity among election offices across the country, the guide provides actionable guidance for officials at all levels of technical competency. It covers key cyber threats to monitor — including malware, ransomware, phishing, website defacements, and generative AI-driven disinformation — and provides a framework for state and local officials to take targeted action based on their respective capabilities.
