3 Ways to Use Industrial Firewalls for Defense in Depth

Dr. Oliver Kleineberg 06.01.2016

An important best practice for industrial security is to implement a Defense in Depth strategy. With this approach, multiple layers of defense are implemented, in contrast to just one defense mechanism, such as a single firewall.

A complementary best practice used as part of a Defense is Depth strategy is Zones and Conduits, as defined in the ISA IEC 62443 standard. This involves segmenting the network into zones of devices with similar security requirements and using conduits to restrict the communication between zones.
