Many vendors are producing firewalls designed for the Industrial Control environment. Some very simple; some quite complex. One idea that is rapidly expanding on the Defense-in-Depth concept and becoming more important is that of “Deep Packet Inspection” or DPI. The idea of not only firewalling a protocol, but firewalling what that message is trying to do, allowing for example, a read but not a write command to pass. A number of vendors have released some sort of DPI firewall, and more are adding theirs to the list.
This webinar will explore the uses and special aspects of the industrial control firewall and will review how a firewall works to protect an ICS network. Subsequent webinars will present some of the specific DPI products available on the market today. Who they are from, what protocols they can filter, and what additional functionality they offer.
