Theory 050/Networks & Telecommunications
Exposure Is Reachability
The claim
Network exposure is set by the ratio of reachable to total hosts rather than by the number of hosts.
01The mechanism
Only reachable hosts can be attacked; a large network with tight segmentation is smaller than its address space.
02Predictions
- P1Exposure should track the ratio.
- P2Growing the network with segmentation should not raise exposure.
03Refutation
Exposure tracking host count would remove the segmentation term.
