Instruction follows security incidents in 2021, 2022, and 2023.
T-Mobile has agreed to make changes to its cybersecurity practises following consecutive data breaches.
After breaches were experienced in 2021, 2022, and 2023, the FCC announced a deal to settle its investigation into past incidents, which hit more than 76 million people during the 2021 breach.
Specifically, the company will need to implement “a modern zero trust architecture,” segment its internal networks, and institute multi-factor authentication for all employees, according to media reports.
“Implementing these practices will require significant—and long overdue—investments,” the FCC said. “To do so at T-Mobile’s scale will likely require expenditures an order of magnitude greater than the civil penalty here.”
In response to the settlement, T-Mobile said: "We take our responsibility to protect our customers’ information very seriously. This consent decree is a resolution of incidents that occurred years ago and were immediately addressed. We have made significant investments in strengthening and advancing our cybersecurity program and will continue to do so."
