Data Centers, Telecom, & Space-Based Systems: Modernizing DHS's Role for Communications, IT Sectors

The Homeland Security Committee's Subcommittee on Cybersecurity and Infrastructure Protection held a hearing on April 30, 2026, to evaluate the Department of Homeland Security's role as the sector risk management agency (SRMA) for the communications and information technology sectors, including hyperscale data centers, telecommunications networks, subsea cables, and space-based communication platforms. Witnesses from industry and government-related organizations discussed challenges such as significant staffing cuts at CISA, the need for modernized authorities and resources, and the importance of public-private partnerships to enhance cybersecurity resilience. The hearing emphasized the criticality of designating data centers and space systems as separate critical infrastructure sectors to ensure focused protection and coordination. Several witnesses highlighted the risks posed by supply chain vulnerabilities, particularly involving Chinese-made components, and called for coherent government policies and increased funding to strengthen defenses. The committee also discussed legislative priorities, including reauthorizing the Cybersecurity Information Sharing Act and improving transparency and community engagement around AI data center development. No specific contract awards or procurement actions were reported, but the discussion underscored the need for increased investment and policy support to bolster cybersecurity infrastructure and sector risk management capabilities.
