Understanding Firewall Technology for Industrial Cybersecurity

White Paper Belden

Robust Security and Unprecedented Flexibility for Highest Network Availability

In this White Paper:

  • The importance of firewalls for implementing Defense-in-Depth & zones/conduits best practices
  • Industrial firewalls & filtering
  • Where & how to use industrial firewalls to secure Industrial Control Systems (ICS)
  • ... and more

You'll be on your way to knowing how to use different firewalls to enhance the security, robustness and resiliency of industrial systems!


“Rather than being a one-size-fits-all device, industrial firewalls come in a variety of form factors with a range of features and technologies optimized to play different roles as part of a comprehensive security architecture.”

“An easy-to-use firewall can be the difference between a solution that is feasible for use or a solution that is more of an obstacle than an enabler in the implementation of a security strategy.”

“By combining different firewall functions in an overall network defense strategy and by positioning the different types of firewalls in the network where they play to their strengths, it is possible to design networks that are prepared for the future and will stand the test of time.”
