What should Steven implement on the firewall to ensure this happens?

Steven’s company has recently grown from 5 employees to over 50. Every workstation has a public IP address and navigated to the Internet with little to no protection. Steven wants to use a firewall. He also wants IP addresses to be private addresses, to prevent public Internet devices direct access to them.

What should Steven implement on the firewall to ensure this happens?
A . Steven should use a Demilitarized Zone (DMZ)
B . Steven should use Open Shortest Path First (OSPF)
C . Steven should use IPsec
D . Steven should enabled Network Address Translation (NAT)

Answer: D

Explanation:

Steven should implement Network Address Translation (NAT) on the firewall to ensure that the IP

addresses of the workstations are private and not directly accessible from the public Internet. NAT translates the private IP addresses of the workstations to a public IP address before they are sent out to the Internet, and vice versa for incoming traffic. This not only hides the internal IP addresses but also allows multiple devices to share a single public IP address, which is essential as the company grows.

Reference: The concept of NAT and its role in protecting internal network resources while allowing Internet access is a fundamental topic covered in the Certified Network Defender (CND) course. It is also a standard practice in network security, aligning with the objectives of ensuring the confidentiality and integrity of network infrastructure.
