Abstract
Systems and methods for detecting a rogue network device at a physical layer include monitoring physical layer characteristics of a wired link at both a first network device and a second network device; determining whether there are detectable variances in the physical layer characteristics; and detecting a rogue network device inserted on the link based on the detectable variances.
