Securing the Industrial IoT is a big design challenge, but one that must be met. Although the original builders of industrial systems did not anticipate a need for Internet connectivity, companies now see the value of connecting to their plants, pipelines, and remote devices, often over the Internet. The looming question: How to maintain a high level of security for a mission-critical system while allowing remote access to the data?
As you can imagine the answer is not simple. What’s called for is a totally new approach, one that is secure by design. This blog entry, published on the ARC Advisory’s Industrial IoT/Industrie 4.0 Viewpoints blog, gives an overview of why standard industrial system architecture is not adequate to ensure the security of plant data on the Internet, and introduces the two main considerations that must go into creating a more secure design.
