The proliferation of cyber threats 1 has prompted asset owners in industrial environments to search for security solutions that can protect their assets and prevent potentially significant monetary loss and brand erosion. While some industries have made progress in minimizing the risk of cyber attacks, the barriers to improving cybersecurity remain high. More open and collaborative networks have made systems more vulnerable to attack. End user awareness and appreciation of the level of risk is inadequate across most industries outside critical infrastructure environments. The uncertainty in the regulatory landscape also remains a significant restraint. With the increased use of commercial off-the-shelf IT solutions in industrial environments, control system availability is vulnerable to malware targeted at commercial systems. Inadequate expertise in industrial IT networks is a sector-wide challenge.
