Why Data Diodes Bolster IoT Security With One-Way Traffic
Like stern traffic cops, data diodes reinforce a one-way route for data traveling through a network, ensuring that the IoT devices behind the diodes won’t be compromised by malicious incoming traffic.
Simple but elegant solutions, data diodes provide hardware-based security to Internet of Things (IoT) environments. These environments have become more vulnerable, as the volume of connected devices grows, and the networks stretch to wider and more remote geographies. For any administrator of an IoT infrastructure, security is the foremost concern today—with good reason.
“IoT devices now make up 32.72% of the infected devices observed,” Nokia noted in its “Threat Intelligence Report 2020,” which chronicles malware activity in networks based on data collected by the company’s security software. “Compared with 2019, the share occupied by IoT devices in the overall device breakdown has increased by 100%, from a previous share of 16.17%.” The threat to IoT endpoints is so severe that Nokia concluded, “Cybercriminals are focusing their effort on IoT and mobile devices.”
“The growing digitalization of critical infrastructure with an increasing number of IoT devices is raising the bar for network security,” wrote Andres Guilarte, global product manager, connectivity and IoT for Siemens Mobility in a response to emailed questions from IoT World Today.
