Background for this topic.
Cybersecurity and Infrastructure Security Agency (CISA) is the U.S. Department of Homeland Security agency for reducing cyber and physical risks to critical infrastructure and federal civilian networks. Created by the 2018 CISA Act, it works with government and industry, publishes alerts and guidance, and coordinates assistance during significant incidents. Its direct federal-network role chiefly covers the Federal Civilian Executive Branch, including .gov; private-sector engagement is often voluntary or sector-specific.
Practitioners use CISA advisories and the Known Exploited Vulnerabilities catalog to prioritize patching where exploitation has been observed, and consult applicable directives and incident-response guidance. CISA supports vulnerability reporting and promotes controls such as multifactor authentication, logging, and tested recovery. A CISA alert is an actionable risk signal, not proof every organization is affected; teams should verify product, version, exposure, and obligations.
CISA and OpenSSF jointly published new guidance recommending technical controls to make it harder for developers to bring in malicious software components into code.

Election cyber threats come from various places, including compromised voting machines, AI deepfakes, and potential physical harm to workers. But CISA has been working diligently with various public and private partners to stymie the risk.
