Through cyber-physical systems, the effects that the digital world can now have on the real world are more noticeable than ever. Organizations should be aware of this because it could give cyber threat actors new ways to compromise someone's physical safety. The internet of things (IoT) expansion and evolution, as well as a shift toward more software-centric and intrinsically internet- and cloud-reliant technologies, are largely to blame for the quick development of cyber-physical systems.

IoT refers to the countless numbers of physical objects that link to one another and share information online. These gadgets could be as commonplace as the smart watch we wear, complex like the cars we drive, or vital like the medical equipment that keeps us alive. IoT that is software-centric fosters innovation and introduces new features more quickly, but it also significantly increases the attack surface. The effects of this become more significant as IoT devices' influence on our physical world grows. Over the past 30 years or so, attacks on IT have changed and advanced.

Why is protecting SDVs crucial? The answer is that cybersecurity will play a big role in vehicle safety in next-generation automobiles. In 2019, distracted driving was a factor in 6% of fatal crashes and 8% of crashes that resulted in injuries in the United States. Think about what may occur if a threat actor managed to distract the driver by compromising the infotainment system in a car. What may a seemingly innocuous loud noise from the car speakers possibly do? This is more than just speculation. A significant vulnerability in a SiriusXM connected vehicle (CV) service that impacts millions of vehicles was found by cybersecurity researchers.
