koudnetwerk
Koudnetwerk is a term used in Dutch information security to describe a network architecture characterized by isolation from untrusted networks. The concept is not standardized and its exact meaning varies by organization, but it generally refers to networks that operate with minimal exposure to external connectivity, or that require controlled bridges to transfer data.
Typical design priorities include physical and logical segmentation, strict access controls, and defined data transfer procedures.
Common use cases are critical infrastructure, industrial control systems, government facilities, and environments handling highly sensitive
Data transfers into or out of a koudnetwerk are tightly regulated, using authorized transfer stations, encrypted
The term stems from Dutch security literature and reflects broader security strategies that favor isolation to
