Christopher Krebs was confirmed Tuesday evening to a top Homeland Security cybersecurity and critical infrastructure post by a Senate voice vote.

Why it matters: National Protection and Programs Directorate (NPPD), a division that the Department of Homeland Security and Krebs both hope to change to something more descriptive, heads DHS' cyber and infrastructure resiliency efforts. Krebs is now officially in charge of NPPD. He had been leading the division in an unconfirmed capacity — officially the "Senior Official Performing the Duties of the Under Secretary."

What he's saying: In a statement, Krebs said "It’s an incredible honor to be confirmed as the Under Secretary; it represents the confidence that the Senate, the President, and the Secretary have in me to do this important job."

• Krebs has been with DHS since March of 2017 — his second stint at the agency. Krebs was previously on Microsoft's policy team and served as Senior Advisor to the Assistant Secretary for Infrastructure Protection in his first run with DHS.
