Just as the digitization and increasing connectivity of business processes has enlarged the attack surface of the IT environment, so too has the digitization and increasing connectivity of industrial processes broadened the attack surface for industrial control networks. Though they share this security risk profile, the operational technology (OT) environment is very different from that of IT. This post looks at the key differences and provides a four-step approach to securing the industrial network.

In industries like utilities, manufacturing, and transportation, the operations side of the business is revenue generating. As a result, uptime is critical. While uptime is important in IT, interdependencies in the OT environment make it challenging to maintain uptime while addressing security threats. For example, you can
