A series of newly discovered TCP/IP software vulnerabilities pose a threat to millions of IoT devices. Undiscovered since the early 1990s, they highlight the need to improve security in an increasingly precarious IoT supply chain.
While the modern-day Internet supports considerable security controls such as encryption, identification, and authentication, this was not always the case. Concerns regarding cybersecurity were largely absent during the initial development and deployment of the early Internet. As a result, many of today’s commonly used security solutions have been designed and applied piecemeal. So it’s no surprise that several newly discovered flaws in the underlying network stack infrastructure, unknown and unpatched since the late 1990s, have recently been discovered. The implications of such vulnerabilities can prove catastrophic for the perpetually growing IoT landscape.
