Q + A + Q + A + Q + A + Q + A + Q + A + Q + A + Q + A + ANDREA CARCANO – NOZOMI NETWORKS CO-FOUNDER As IT and OT and even IoT worlds converge, anyone who is sceptical of the need for secure cyber and physical systems should consider the results of a critical infrastructure executive survey that Nozomi Networks recently conducted with Newsweek Vantage. Almost all of the 415 executives surveyed say their organisation has suffered at least one security incident in the past 12 months and half have experienced two or more. Nearly a quarter say the time between compromise and discovery exceeded 24 hours. Just as worrying, employees are regarded as the biggest human source of vulnerability – bigger even than cyber-criminal groups. Former employees are also a security risk. These statistics contradict the common belief that terrorists and state actors are the biggest risk. More than half of the breaches reported are cyber incursions into IT systems, but physical incursions into IT and OT systems are very common too, and this is why it’s important to approach security from both a cyber and a physical perspective. Our survey found the more integrated IT, OT, IoT and physical systems are, the greater the degree of security, but because they are so integrated, these systems are more vulnerable to attack. Executives have to balance the need for efficiency with the imperative for security. Furthermore, too many organisations are under the impression that their approach to IT, OT and physical system security is adequate, until they find that it isn’t. More than a third of executives say that an actual cyberbreach caused them to develop a holistic approach to their organisation’s cyber/physical security. In response to cyber-physical threats, two thirds have integrated some of their IT, OT and physical systems, and the process is continuing. A fifth have integrated all their systems. But here’s the thing, executives see the main advantages of integration as more responsiveness and better decision-making. “ THE M ORGANIS OBSTA CULTUR DIFFER OPINION IT AND WHAT N BE SEC www.intelligentcio.com
