Question

What is the purpose of creating a DMZ during network firewall implementation?

1) To provide a buffer zone between the internet and internal network
2) To allow external users to access specific resources in the internal network
3) To enhance network security by isolating critical systems
4) All of the above

Answer 1

The purpose of creating a DMZ during network firewall implementation is to serve as a buffer zone, allow controlled access to specific internal resources, and enhance overall network security by isolating critical public-facing systems from the internal network.

Step-by-step explanation:

The purpose of creating a DMZ (Demilitarized Zone) during network firewall implementation is indeed all of the above options. Specifically, a DMZ serves multiple functions:

• It provides a buffer zone between the public internet and the internal network, which adds an additional layer of security.
• It allows external users to access specific resources, such as web servers or email servers, without having direct access to the entire internal network.
• It enhances network security by isolating critical systems that can be accessed from the internet from the rest of the internal network, thereby reducing the risk of an internal breach if the public-facing systems are compromised.

By implementing a DMZ, organizations are able to improve their overall security posture and protect sensitive data and services from potential threats.
