Abstract
Systems and methods for detecting a rogue network device at a physical layer include obtaining physical layer characteristics of a link between a first network device and a second network device; analyzing the physical layer characteristics of the link; and detecting the rogue network device based on the analyzed physical layer characteristics, wherein the rogue network device was inserted in the link and causes detectable variances in the physical layer characteristics. The physical layer characteristics can include one of noise introduced in clock frequency and jitter.
