The Cybersecurity and Infrastructure Security Agency (CISA) leads the national effort to defend critical infrastructure against the threats of today, while working with partners across all levels of government and in the private sector to secure against the evolving risks of tomorrow.
This time last year, the Department of Homeland Security (DHS) made a commitment to the American people: it should not be easy to impersonate the federal government through spoofing-related phishing campaigns.
The Department of Homeland Security strives every day to help federal agencies, state, local, territorial and tribal governments, and critical infrastructure asset owners and operators raise the baseline of cybersecurity. With the continuous growth of connected systems and rapid technology evolution, cyber vulnerabilities are being discovered in more devices and systems than ever before.
The Department of Homeland Security is designated as the Sector-Specific Agency for the Information Technology Sector.
