Understanding Cybersecurity of Mobile Networks Act

Introduced February 21, 2023

AI-Generated Summary

Updated January 20, 2026 at 3:53 AM UTC

The Understanding Cybersecurity of Mobile Networks Act requires the Commerce Department’s Assistant Secretary for Communications and Information to produce a detailed report on the security of U.S. mobile service networks. The report, due within one year, must examine vulnerabilities, encryption practices, and surveillance tools, and will be sent to the House Energy and Commerce Committee and the Senate Commerce, Science, and Transportation Committee. It involves input from a wide range of federal agencies, industry players, researchers, and international stakeholders, and focuses on commercial mobile services used by U.S. consumers, businesses, and government agencies.

Key Provisions

  • Directs the Assistant Secretary of Commerce to submit a report on mobile network cybersecurity within one year of enactment, consulting the Department of Homeland Security.
  • Specifies the report must assess how mobile providers address vulnerabilities identified by researchers, standards bodies, and federal agencies, and discuss customer considerations, best‑practice adoption, and encryption/authentication usage.
  • Requires estimates on the prevalence and cost of cell‑site simulators and other surveillance technologies used by adversaries in the United States.
  • Mandates consultation with agencies such as the FCC, NIST, intelligence community, DHS, as well as industry, academic, and international stakeholders during report preparation.
  • Limits the report’s scope to mobile service networks (excluding 5G protocols) and to vulnerabilities that have been exploited in real‑world settings or are feasibly exploitable.
  • States the report will be unclassified with a possible classified annex, and any exploitable unclassified details must be redacted for public release but provided unredacted to the committees.
