Koen presented some preliminary findings of his systematic survey paper on security requirements for the Industrial Internet of Things at the CPS-IoT week earlier this year in Montreal, Canada. These findings were mainly about how IIoT security research has progressed in the past 6 years, and which countries are most active in this area.
Since then, he has further analyzed the papers that were found and has produced a finished version of the survey. This version discusses a variety of security topics that were addressed in the papers, and distills them into a set of categorized security requirements relating to authentication, access control, maintainability, resilience, data security and data sharing, security monitoring, network security, and models and methodologies. The full version of the survey has been submitted to a journal and will hopefully be published later this year.
