FCC Expands Cybersecurity Rules to Alerting and Cable Gates
The compliance burden has moved into the trusted path itself. The FCC is now making security a licensing and operating requirement for systems that carry emergency alerts and for the terminals that land submarine cables, and it reaches third-party suppliers as part of that trust chain.
The new rules require stronger passwords, faster patching, firewalls, and alert authentication for EAS and WEA participants. The Commission also adopted the first major update to submarine cable rules in decades, with cybersecurity standards tied to licensing reviews for undersea cable providers and landing-station operators.
That shifts the baseline from informal hygiene to enforceable controls around systems that can spoof public warnings or disrupt critical communications. It also widens supply-chain scrutiny beyond the primary operator to the vendors and terminal equipment that sit between the cable and U.S. facilities.
