What is a network demilitarized zone (DMZ)?

1. The safest part of the network, used for the security infrastructure

2. The part of the network you don't secure, for example a network segment used for visitors to access the internet

3. The database management zone

4. The network zone where you put servers that serve the outside, to limit the exposure

The correct answer is: The network zone where you put servers that serve the outside, to limit the exposure

A network demilitarized zone (DMZ) is a specific area of a network that is designed to enhance security by providing a buffer between an internal network and external networks, such as the internet. The primary function of a DMZ is to host servers that need to be accessible from the external network while limiting their exposure and protecting the internal network from potential threats. In this context, the DMZ acts as a controlled environment where external users can access certain services (like web servers, email servers, or FTP servers) without having direct access to the more sensitive parts of the network that contain critical internal data or resources. This design helps to mitigate the risk associated with exposing internal systems to the internet, as it allows security policies to be applied specifically to the servers in the DMZ, thereby safeguarding the internal network. The other choices do not accurately reflect the purpose of a DMZ. The safest part of the network would typically be the internal network infrastructure, while the notion of a segment that is unsecured contradicts the security principles underlying the concept of a DMZ. A database management zone is not a recognized term relevant to DMZ. Therefore, the option identifying the DMZ as a network zone for servers that serve outside traffic correctly encapsulates its
