1. A method, comprising: receiving, at a device in a network, attack detectability metrics from nodes along a path in the network; computing, by the device, a path attack detectability value using the attack detectability metrics from the nodes along the path, wherein the path attack detectability value quantifies how well one or more attack detectors are able to detect an attack along the path; determining, by the device, that the path attack detectability value does not satisfy a network policy; and adjusting, by the device, one or more routing paths in the network based on the path attack detectability value not satisfying the network policy.
