b) Screened subnet

Explanation:

In Computer science, Firewall implementation and design for an enterprise can be a daunting task. Choices made early in the design process can have far-reaching security implications for years to come.

Screened subnet firewall architecture is designed to host servers that offer public services.

In network security and management, one of the network architecture used by network engineers for the prevention of unauthorized access of data on a computer is a screened subnet. A screened subnet can be defined as a network architecture that uses a single firewall with three screening routers as a firewall.

<em>A screened subnet is also known as a triple-homed firewall, this is because it has three (3) network interfaces;</em>

1. Interface 1: it is known as the external or access router, which is a public interface and connects to the global internet.

2. Interface 2: it is known as the demilitarized zone or perimeter network, which acts as a buffer and hosted public servers (bastions host) are attached herein.

3. Interface 3: it is known as the internal router, which is a subnet that connects to an intranet.

<em>The screened subnet when properly configured helps to prevent access to the internal network or intranet. </em>
