Overview

Over the last three years, engineering in IoT has seen massive changes primarily driven by Microsoft, Google and Amazon. These large behemoths have invested billions of dollars to develop IoT platforms that are  more easy to manage and secure some perimeters of data. Also IoT edge has gained a lot of momentum in both research and deployment as only means for practical IoT implementation.  5G is also promising to transform the business of IoT.  This has led to an unprecedented large swath of new areas of research funding in IoT.

However large scale adaptation of IoT is slow due to security concerns at various levels. Securing Firmware and Gateways is far from ideal.  One of the major issue is, disagreement among different large IoT vendors on the matter of security.  Microsoft Azure, Amazon AWS have  pushed forward with its own security standards. Where as NIST is placing a more comprehensive one.  OWASP model of 10 layers of IoT security did some impact but overall failed to get much ground due to non-adoption from major IoT platform like Azure or Google.
 

Second large area of concern is security of Firmware. Primarily most of the Firmware are  still vulnerable to any patching be it via OTA ( over the top ) or locally via a hardware port.

 

Course Objective

  1.  Give introduction of all the technology stacks, data model and vulnerability  of IoT
  2.  Drawing the layers of vulnerability at each stack and between the stack
  3.  Vulnerability from vendors and third party devices
  4.  Learning about the NIST standard of IoT security
