Closing keynote: The White House is serious about cybersecurity

The Biden Administration has made strengthening U.S. cyber defenses a top priority in its first two years. Among its accomplishments: new legislation, including the Strengthening American Cybersecurity Act of 2022, executive orders to firm up the federal government's cybersecurity and the establishment of a new Office of the National Cyber Director. Kemba Walden left a job in Microsoft's Digital Crimes Unit to come back to public service as part of that new office. She is now focused on giving private sector companies more clarity on when to report cyber breaches to the government, who to report those breaches to, and making sure that government agencies share information with each other and act on it.
