Free Whitepaper

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. The industry now faces the challenge to integrate security solutions in legacy OT systems.

This whitepaper 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 review

  • Full-duplex Ethernet and Its Use in Industrial Control Protocols
  • Why a mirror port should not be used to build security solutions
  • Why a mirror port will drop frames even if a link is not saturated
