  The increase of cyberattacks using IoT devices has exposed the
vulnerabilities in the infrastructures that make up the IoT and have shown how
small devices can affect networks and services functioning. This paper presents
a review of the vulnerabilities of the wireless technologies that bear the IoT
and assessing the experiences in implementing wireless attacks targeting the
Internet of Things using Software-Defined Radio (SDR) technologies. A
systematic literature review was conducted. The types of vulnerabilities and
attacks that can affect the wireless technologies that stand the IoT ecosystem
and SDR radio platforms were compared. On the IoT system model layer,
perception layer was identified as the most vulnerable. Most attacks at this
level occur due to limitations in hardware, physical exposure of devices, and
heterogeneity of technologies. Future cybersecurity systems based on SDR radios
have notable advantages due to their flexibility to adapt to new communication
technologies and their potential for the development of advanced tools.
However, cybersecurity challenges for the Internet of Things are so complex
that it is needed to merge SDR hardware with cognitive techniques and
intelligent techniques such as deep learning to adapt to rapid technological
changes.
