Is there a Trojan! : Literature survey and critical evaluation of the
  latest ML based modern intrusion detection systems in IoT environments
Vishal Karanam
IoT as a domain has grown so much in the last few years that it rivals that
of the mobile network environments in terms of data volumes as well as
cybersecurity threats. The confidentiality and privacy of data within IoT
environments have become very important areas of security research within the
last few years. More and more security experts are interested in designing
robust IDS systems to protect IoT environments as a supplement to the more
traditional security methods. Given that IoT devices are resource-constrained
and have a heterogeneous protocol stack, most traditional intrusion detection
approaches don't work well within these schematic boundaries. This has led
security researchers to innovate at the intersection of Machine Learning and
IDS to solve the shortcomings of non-learning based IDS systems in the IoT
ecosystem.
  Despite various ML algorithms already having high accuracy with IoT datasets,
we can see a lack of sufficient production grade models. This survey paper
details a comprehensive summary of the latest learning-based approaches used in
IoT intrusion detection systems, and conducts a thorough critical review of
these systems, potential pitfalls in ML pipelines, challenges from an ML
perspective, and discusses future research scope and recommendations.
