The Industrial Internet of Things (IIoT) has been a hot topic of late. One key consideration that will impact its acceptance rate and ultimate success is security. A successful attack on an IIoT system could result in the loss of sensitive data, interruption of operations, and destruction of systems. This will result in damage to brand and reputation, material economic loss and damage to critical infrastructure. Worse, there could be damage to the environment, injury or loss of human life. A secure IIoT solution is comprised of a variety of elements, including secure products, secure protocols, a secure network, ongoing security monitoring, and employees with cybersecurity expertise.
