In 2016 there are 5.5 million connected devices being added per day with a minimum estimate of nearly 21 billion internet-connected “things” running our world by 2020. On October 21, 2016 the Mirai variant of a botnet DDoS attack was used against Dyn’s managed DNS service. It took 11 hours to restore most of their services and user access was degraded and denied during that period. Is such an attack feasible against industrial and critical infrastructures? What would be the obstacles and opportunities for bad actors to use this publicly available malicious code to disrupt and even cause public harm? In this talk Belden’s Erik Schweigert will: Discuss the levels of challenge for and against this type of industrial and critical infrastructure threat Outline how the Mirai botnet and similar code can infect and take control of normally harmless and helpful smart devices Show how Belden’s Tofino Xenon technology with granular Deep Packet Inspection could protect against similar DDoS attacks aimed at control systems
