Tier 1:
The five Internet service providers (ISPs) in the U.S. that own and operate the large, national network of fiber-optic cables on which Internet and other cyberspace traffic runs to the major cities. Smaller or regional ISPs use a Tier 1 to connect to Internet addresses that are on their own network.

Trapdoor:
Unauthorized software maliciously added to a program to allow unauthorized entry into a network or into the software
program. Often after an initial entry, a cyber criminal or cyber warrior leaves behind a trapdoor to permit future access to be faster and easier. Also referred to as a Trojan, or Trojan horse, after a ruse supposedly employed by Bronze Age Greek warriors to leave behind at Troy a commando team hidden inside a statue of a horse.
