Abstract: Secure external hubs for coupling peripheral devices to host computers are disclosed. Each peripheral device includes device identification (ID). Peripheral devices may be securely coupled to a host computer by designating authorized device IDs in response to an administrator input received via an administrator port of a hub, authorizing the peripheral devices connected to the hub based on the designated authorized device IDs, and enabling communication between authorized peripheral devices connected to the hub and a communication cable and preventing communication between unauthorized peripheral devices connected to the hub and the communication cable.
