These are the November 4 and December 2, 2021 remote hearings on "The Evolving Cybersecurity Landscape," held before the U.S. House Committee on Transportation and Infrastructure. From the opening statement of Peter A. DeFazio: "Today, we are going to hear about the challenges and gaps in protecting our Nation's transportation systems and critical infrastructure from cyberattacks, and recommendations from private industry and cybersecurity experts on how to close those gaps. [...] But when it comes to the Nation's critical infrastructure and transportation networks--pipelines that fuel our economy, water and wastewater treatment plants, shipping, aviation, railroads, and highways that play a critical role in bringing vital supplies to all Americans--getting everything right every time must be the goal. Lives are on the line. And each day, when you turn on a faucet, flush your toilet, or when you board a plane, fill up your car with gas, you trust that these systems will work." Statements, letters, and materials submitted for the record include those of the following: Scott Belcher, Megan Samford, Thomas L. Farmer, Michael A. Stephens, John P. Sullivan, and Gary C. Kessler.
