A bastion host is a gateway between an inside network and an outside network. Used as a security measure, the bastion host is designed to defend against attacks aimed at the inside network.

Depending on a network’s complexity and configuration, a single bastion host may stand guard by itself, or be part of a larger security system with different layers of protection.
