New research by Zscaler highlights how companies are putting themselves at risk through the use of poorly secured IoT devices. The report found that a staggering 91.5% of IoT data transactions on enterprise networks are not encrypted. If a threat actor manages to intercept that traffic, they can therefore access and manipulate that traffic by means of a man-in-the-middle (MitM) attack.
The research also shows that a mere 18% of IoT devices encrypts all traffic using Transport Layer Security (TLS). 41% of devices do not use TLS at all, and another 41% use TLS selectively, meaning for certain connections only.
