Tackling security vulnerabilities of the industrial IoT

As a result, most have either no authentication or weak authentication, like passwords that can be easily sniffed from the wire.“Second, connectivity between corporate IT networks and OT networks has increased significantly because of the need to get real-time intelligence from production. Whether it’s a gas pipeline, a factory floor, or a well site, companies want to optimize their operations and collect real-time intelligence. This means that the attack surface has increased: There are many more ways for attackers to get into industrial networks.“Third, the group of potential attackers has also increased. From a destructive malware point of view, today, it includes nation-state threats, primarily Russia, North Korea, and Iran. Also China, which is less interested in malware and more interested in stealing intellectual property from industrial networks. Attackers now include sophisticated nation-states, cybercriminals with ransomware for shutting down a plant, and hacktivists. They also include third-party risks.”EE Times interviewed a host of cybersecurity experts for this Special Project. In the following pages, we will share some of the key points that they laid out for us as to why the IIoT is so vulnerable to cyberattacks.  Leave a Reply Cancel reply You must Register or Login to post a comment.
