What is the main characteristic of a single-homed Bastion Host?

A single-homed Bastion Host is designed to provide a strong defense point in a network while being connected to one single network interface. The main characteristic of such a setup is that all incoming and outgoing traffic must go through this one interface, which allows for easier monitoring and management of the traffic. This streamlined traffic flow makes it simpler for security measures to be implemented, such as firewalls or intrusion detection systems, as there is only one point where traffic can be analyzed or controlled.

The choice to limit the Bastion Host to a single network interface enhances its security posture by minimizing exposure to potential attacks from multiple interfaces. By concentrating all data flow through one channel, administrators can implement stricter security protocols that can adequately monitor and log all activity, thereby facilitating better detection and response to any unauthorized access attempts or breaches.
