LANGEVIN, A REP- RESENTATIVE FROM RHODE ISLAND, CHAIRMAN, SUB- COMMITTEE ON INTELLIGENCE AND EMERGING THREATS AND CAPABILITIES, COMMITTEE ON ARMED SERVICES Mr. LANGEVIN. The subcommittee will come to order. So, good afternoon, everyone. I am pleased to welcome everyone here today to the joint hearing with the Committee on Oversight and Reform Subcommittee on National Security about the security of the Nation’s internet architecture. I am particularly thankful to my good friend Congressman Lynch from Massachusetts, my neigh- bor in New England, and his staff for working so diligently in mak- ing today possible, along with the ranking members of both sub- committees. Today we are here to conduct what I believe is much-needed oversight regarding the security of the internet’s underlying archi- tecture, namely, the components, physical sites, and the assets that are necessary for the internet to operate. Defending the United States assets in this global telecommuni- cations network requires a whole-of-government approach, and I am concerned that the government is not approaching the subject in a cohesive or comprehensive manner, creating significant risk for the Nation. Both the Oversight subcommittee and the Armed Services sub- committee are seeking a better understanding of the policies, regu- lations, and guidelines and interagency agreements that govern the protection of this critical infrastructure. To the extent that there are gaps, we are also interested in learning whether legislative so- lutions may be needed. Most people think of the internet as the sites they visit, the ap- plications they use, and the emails they send. In other words, the people’s understanding of what the internet is, is very much tied to how they engage with it. However, this leaves out an entire ar- chitecture that enables the flow of information around the world (1) 2 and into people’s palms. This architecture includes the high-capac- ity cables buried under the ground and laid below the sea, the cable landing stations that connect the cables from continent to continent, and the internet exchange points, or IXPs, that serve as a clearinghouse for data between internet service providers and content delivery networks. These are all examples of physical sites and tangible items that are required for the internet to operate ef- fectively. While these physical sites are critical components of the cyber landscape, they are generally viewed as distinct from the network’s protocols and software that are more familiar to people’s under- standing of the internet. However, they are just as important to internet operations. After all, unplugging a network cable is just as effective as a denial-of-service attack, maybe even more so. From the government’s perspective, attacking the subject of internet architecture security is difficult, due to the departments’ and agencies’ overlapping jurisdictions, responsibilities, and capa- bilities. And I am concerned that the executive branch has frag- mented internet architecture security among multiple departments as opposed to conceptualizing the internet as a single ecosystem with departments working collaboratively. For example, the Department of Homeland Security serves as the government lead for all critical infrastructure, and as the sector- specific agency for the telecommunications sector. Meanwhile, the Department of Commerce’s National Telecommunications and In- formation Administration, or NTIA, is principally responsible for advising the President on telecommunications and information pol- icy issues, and develops national policies on internet use and cyber- security. Separately, the Department of Defense is broadly responsible for defense of the Nation. Independent regulatory agencies, like the Federal Communications Commission, also have important respon- sibilities for ensuring security. To top it all off, many of these ex- change points are connected to international providers. So I have no doubt that these agencies work together broadly. However, I am very worried that by carving out discrete lanes in the road, there are seams left unaddressed in the middle, and I am concerned that internet architecture security is one of those seam issues. Holistic internet architecture security has been generally ne- glected, I believe, with organizations remaining firmly in their lanes rather than approaching the problem collectively. So,
