Demilitarized Zone (DMZ)

A DMZ, or demilitarized zone, is a physical or logical sub-network that acts as a separate layer of security in network architecture, positioned between an organization's internal private network and the external public network, typically the internet. This configuration is used to enhance security by creating a controlled buffer zone where external users can access specific network services without gaining direct access to the internal network.

Advantages of Implementing a DMZ:

Implementation Considerations:

In conclusion, a DMZ is a critical component of network security for organizations that need to ensure the availability of services to external users while protecting their internal networks from potential cyber threats. Its strategic use of isolation and controlled access serves as a fundamental defense mechanism in modern network security architectures.
