FTTH, or Fiber to the Home, is a broadband design that runs fiber optic cable directly to a residence or business premises. Compared with older copper access, FTTH offers higher bandwidth, lower latency, and more stable service, which is why it is widely used for modern internet, voice, and IPTV delivery.
In cyber security, FTTH matters because the access layer is part of the attack surface. Adversaries may target customer premises equipment, optical network terminals, provisioning systems, or weak authentication on management interfaces. Physical tampering with fiber cabinets or drop lines can also disrupt service. Defenders reduce risk with strong device inventory, secure remote management, access control, logging, and careful change management. In practice, FTTH is not just a speed upgrade: it is a large-scale operational environment that must be protected against misconfiguration, abuse, and outages.
