A demilitarized zone (DMZ) is typically implemented as a buffer zone or intermediary network between an organization’s internal networks and external or higher-level networks. In a common industrial control system (ICS) architecture, such as the Purdue model, Level 4 (Enterprise level) and above must communicate with Level 3 and below (Control levels) through the DMZ. This configuration helps ensure that external or less-trusted segments do not directly connect to the critical internal networks without passing through protective layers, thereby reducing the risk of unauthorized access or cyberattacks.
