Full duplex capture in industrial networks

The convergence of IT and OT in the context of Industry 4.0 has led to a crowded market of security solutions targeting the shop floor on different levels. This white paper will explore why those mirror ports shouldn’t be used to build security solutions. Based on the hardware commonly used in Industrial Networks, we will specifically look at:

How it all works

Why a mirror port will drop frames even if a link is not saturated

Full-duplex Ethernet and Its Use in Industrial Control Protocols
