Abstract

Aspects of the subject disclosure may include, for example, accessing a profile including an expected fingerprint of expected parameters for received signals associated with a network path comprising a wired connection between network devices, comparing a fingerprint with the expected fingerprint where the fingerprint is generated from parameters measured from a signal, and authenticating a network device along the network path associated with the transmitting of the signal according to the comparing. Other embodiments are disclosed.
