Christopher Krebs served as the first Director of the Cybersecurity and Infrastructure Security Agency (CISA). Krebs was originally sworn in on June 15, 2018, as the Under Secretary for the predecessor of CISA, the National Protection and Programs Directorate (NPPD). Krebs was nominated for that position by President Donald Trump of the United States in February 2018. As Director, Krebs oversaw CISA's efforts to defend civilian networks, manage systemic risk to National Critical Functions, and work with stakeholders to raise the security baseline of the nation's cyber-infrastructure and physical infrastructure. In November 2020, President Trump fired Krebs for contradicting Trump on the prevalence of election fraud in the 2020 presidential election.
Krebs holds a bachelor's degree in environmental sciences from the University of Virginia in 1999 and a Juris Doctor from the Antonin Scalia Law School at George Mason University in 2007.
