Missed Opportunities: Measuring the Untapped TLS Support in the Industrial Internet of Things. (arXiv:2206.00322v1 [cs.CR])

The ongoing trend to move industrial appliances from previously isolated
networks to the Internet requires fundamental changes in security to uphold
secure and safe operation. Consequently, to ensure end-to-end secure
communication and authentication, (i) traditional industrial protocols, e.g.,
Modbus, are retrofitted with TLS support, and (ii) modern protocols, e.g.,
MQTT, are directly designed to use TLS. To understand whether these changes
indeed lead to secure Industrial Internet of Things deployments, i.e., using
TLS-based protocols, which are configured according to security …
