The Cybersecurity and Infrastructure Security Agency Act of 2018 (CISA Act) was signed into law on November 16, 2018, reorganizing the National Protection and Programs Directorate (NPPD) in DHS to become the new Cybersecurity and Infrastructure Security Agency (CISA), headed by the Director of Cybersecurity and Infrastructure Security, who will be an Under Secretary of the Department of Homeland Security.
CISA is tasked with leading the national effort to defend critical infrastructure against physical and cyber threats, and will comprise three divisions: the Cybersecurity Division, the Infrastructure Security Division, and the Emergency Communications Division. Both the Office of Cybersecurity and the Office of Infrastructure Security were previously part of the NPPD, while the Office of Emergency Communications is new. The NPPD’s Office of Biometric Identity Management will not be part of the CISA, but rather will be in DHS’s Management Directorate.
