What Does Physical Disconnection at Layer 1 Actually Mean?

Every network security tool operates at Layer 2 or above. Firewalls, encryption, segmentation, authentication. They all assume a physical connection exists. Firevault removes the connection itself.

The OSI Model

Seven Layers. One Foundation.

The OSI model defines how networks communicate in seven layers. Every layer above Layer 1 depends on a physical connection. Remove the physical connection and the entire stack above it becomes irrelevant.

Remove Layer 1. Remove the attack surface.

Every threat from Layer 2 through Layer 7 requires a physical connection to exist. DDoS attacks need an IP address. Ransomware needs network access. Lateral movement needs connected infrastructure. Physical disconnection at Layer 1 makes all of them irrelevant.
