What role does the firewall play in the protection of operational technology (OT) networks and systems? Many would say that it’s the defensive mechanism to protect that environment from IT and the outside world. For the operators responsible for uptime of that critical system, the firewall is the perimeter protection that keeps others out. It’s…

As businesses and organizations scale and grow, their network infrastructure can also grow increasingly large and complex. Using a flat network structure (all devices connected on one server) makes it easier for cybercriminals to roam freely and unimpeded in the system in the event of a successful cyber attack. Implementing network segmentation best practices can…
