Trying to secure the industrial network in one go is like boiling the ocean. Better to view it as a journey. At each step in the journey, you’ll make incremental changes to people, process, and technology. Minimal security. This is the current state for most manufacturers. If you’re here, you’ve segmented the industrial network from the IT network. Traffic can’t cross from the IT network to the industrial network without clearing the DMZ. You can block malware from entering the industrial network. You can block malware from leaving the industrial network to infect the enterprise network. But if the industrial network is exposed to malicious software, you don’t have a way to contain it. That means the malware might affect multiple manufacturing cells or production lines — even multiple plants.
