What is the main advantage of implementing a DMZ?

The primary advantage of implementing a DMZ, or Demilitarized Zone, in a network architecture is the increased internal security through isolation. A DMZ serves as a buffer zone that separates the untrusted external network (like the public internet) from the trusted internal network. By placing certain services, such as web servers or email servers, in the DMZ, organizations can ensure that any exposure to external threats does not directly compromise the integrity of the internal network.

This isolation is crucial because it mitigates the risk of attacks. If a server in the DMZ is compromised, the attacker would have limited access to the internal network, protecting sensitive data and resources. Furthermore, firewalls often control traffic between the DMZ and both the external and internal networks, adding an additional layer of security.

The other options do not correctly capture the main advantage of a DMZ. Improved bandwidth management relates to traffic optimization and isn't the primary purpose of a DMZ. While public access to certain services located in the DMZ exists, it doesn't enhance security; rather, it poses a risk needing managed access. Lastly, a DMZ typically increases the need for firewalls to ensure secure traffic management rather than reducing the need. By understanding the role of a DMZ
