Device onboard occurs when a new device is added to the restricted IoT ecosystem. Eavesdropping may
take place during the onboard step of a new device where the hacker can intercept secret keys that are
used to establish communications within a constrained network.
Final Thoughts
The potential for unpredictable cascading effects of vulnerabilities and poor security in the IoT greatly
affects the overall security of the Internet. Ensuring that these devices are secure is the shared
responsibility of its stakeholders. For example, manufacturers need to address known vulnerabilities in
succeeding products, release patches for existing ones, and report the end of support for older products.
As a general security measure, it’s strongly recommended to protect network access to devices with
appropriate mechanisms, and in some cases, isolate them to make difficult their exploration and doing it
a time-consuming task from the cybercriminals’ point of view.
At last but not least, let’s take IoT security seriously because this field has been used massively by
cybercriminals to compromise organizations and their networks turning this into a big and real threat in
2021.
