D3-BDI

Isolate
Broadcast Domain Isolation

Definition

Broadcast isolation restricts the number of computers a host can contact on their LAN.

How it works

Software Defined Networking, or other network encapsulation technologies intercept host broadcast traffic then route it to a specified destination per a configured policy.

This can be implemented within hypervisors, networking hardware (WAPs, switches, routers), or virutal hardware.

Considerations

This technique is highly dependent on network infrastructure and networking requirements.

Artifact Relationships

This defensive technique relates to specific digital artifacts.
