Lessons learned and systematic approaches

IoT systems can be highly complex implementations that encompass many technology layers. Each layer has the potential to introduce new vulnerabilities into the overall IoT system. Our discussions related to potential airline attacks as well as real-world automobile attacks provide glimpses into understanding how overcoming the vulnerabilities of each component within a system is critical in combating highly motivated attackers from reaching their goals.

This becomes even more concerning as the IoT intersects safety and security engineering in the physical and electronic worlds. Described earlier, collaboration between the security engineering discipline and other engineering disciplines is needed now, to allow system designers to build security into the foundations of their products and guard against attacks that focus specifically on removing, dismantling, or reducing the effectiveness of safety controls in IoT CPS.
