Nicole Eagan, the CEO of Darktrace, addressed the WSJ CEO Council Conference in London, mentioning the following: "There's a lot of internet-of-things devices, everything from thermostats, refrigeration systems, HVAC systems, to people who bring in their Alexa devices into the offices. There's just a lot of IoT. It expands the attack surface, and most of this isn't covered by traditional defenses." Eagan gave one memorable anecdote about a case Darktrace worked on in which a casino was hacked via a thermometer in an aquarium lobby. "The attackers used that to get a foothold in the network," she said. "They then found the high-roller database and then pulled that back across the network, out the thermostat, and up to the cloud." Today we are witnessing a surge of innovation in disruptive technologies such as Artificial Intelligence (A.I.) and the Internet of Things (IoT). The intersection of these trends has a profound impact on the way we conduct our business and lives. IoT integrates various sensors, objects, and smart nodes that are interoperable through its embedded computing system. The wide distribution of IoT nodes and the private nature of data that are collected and transferred by these IoT devices made security a major challenge. Conduct research and appraise IoT architecture and discuss the major security breaches that exist in IoT environments.
