Final answer:
Bastion hosts are specifically designed for the Demilitarized Zone (DMZ) of a network, acting as a secure entry point and usually accompanied by firewalls for additional security.
Step-by-step explanation:
A bastion host is a special-purpose computer on a network specifically designed and configured to withstand attacks, so named by analogy to the bastion, a military fortification. The computer generally hosts a single application or process, for example, a proxy server or load balancer, and all other services are removed or limited to reduce the threat to the computer.
Bastion hosts are designed for a specific network area known as the Demilitarized Zone (DMZ). A bastion host is a system deployed to stand as a defended entry point to an internal network and is typically heavily secured due to its high exposure to attacks, being directly accessible from the internet. Firewalls often accompany bastion hosts to create a layered security approach where the bastion host acts as a gateway for external traffic attempting to connect to internal services.
