What characterizes a multi-homed bastion host?

• A. A firewall device with at least two network interfaces
• B. A single interface connected only to the internal network
• C. A device that connects only to external networks
• D. A standard server without firewall capabilities

Answer: (A)

A multi-homed bastion host is primarily characterized by having at least two network interfaces, which enables it to connect to multiple networks. This configuration allows it to perform essential security functions by being placed between an internal network and external networks, such as the internet. The use of multiple interfaces facilitates control over traffic flow and enhances security policies, effectively enabling the host to serve as a specialized firewall device. This design also supports different network segmentation, allowing for better management of security zones, such as a demilitarized zone (DMZ) where public services can be hosted while protecting the internal network. By employing this architecture, organizations can better defend against attacks and unauthorized access, as the host can constantly monitor and filter incoming and outgoing traffic across its different interfaces.
