Guide for Domain Separation

What is Domain Separation?
Domain Separation isolates areas where resources are located, preventing incidents that can compromise your assets. It divides different areas or layers of the network to limit an incident to a particular domain and stop it from spreading across the system.

Importance of Domain Separation
Domain Separation beyond reducing the risk of system failure, can also limit the extent of potential damage if an incident occurs. It can limit attacks by requiring that a user has different credentials for different domains, making movement across domains more difficult for potential attackers.

How does Domain Separation work?
Often, domains are separated by routers, switches, or other networking hardware. However, some high-level applications can separate domains too, like the operating systems or security controls like firewalls.
