Cybersecurity and Infrastructure Protection

The Cybersecurity and Infrastructure Protection Subcommittee is a specialized division of the House Committee on Homeland Security that focuses on a critical slice of national security: protecting America's digital and physical infrastructure from cyber threats. As a subcommittee, it conducts initial hearings and reviews legislation before matters move to the full committee, which has final authority to report bills to the House floor. The subcommittee's jurisdiction is narrow but vital—it maintains oversight of the Cybersecurity and Infrastructure Security Agency (CISA) and other cybersecurity operations within the Department of Homeland Security.

The subcommittee's work centers on three interconnected priorities: protecting federal networks from cyberattacks, strengthening the security and resilience of critical infrastructure that underpins national security and the economy, and fostering cooperation between government agencies and private-sector operators of essential services across 16 critical infrastructure sectors. This partnership focus reflects the reality that much of America's critical infrastructure—power grids, water systems, financial networks, and communications—is owned and operated by private companies that must coordinate with federal authorities.

Under the leadership of Chair Andrew Ogles (R-TN) and Ranking Member Eric Swalwell (D-CA), the subcommittee has held multiple hearings in 2025 and early 2026. Recent activity includes a January 2026 hearing on strengthening U.S. offensive cyber capabilities to counter threats from China, Russia, and Iran, and a December 2025 joint hearing examining cybersecurity risks posed by artificial intelligence and quantum computing. The subcommittee also advanced legislation in 2025, including bills to reauthorize DHS cybersecurity grant programs for state and local governments and to address emerging cyber threats from state-sponsored actors.
