Fuzzing the Internet of Things: A Review on the Techniques and Challenges for Efficient Vulnerability Discovery in Embedded Systems

With a growing number of embedded devices that create, transform, and send data autonomously at its core, the Internet Things (IoT) is reality in different sectors, such as manufacturing, healthcare, or transportation. this expansion, IoT becoming more present critical environments, where security paramount. Infamous attacks, Mirai, have shown insecurity power IoT, well potential large-scale attacks. Therefore, it important to secure these systems form backbone IoT. However, particular nature their resource constraints mean most cost-effective manner securing them before they are deployed, by minimizing vulnerabilities ship. To end, fuzzing has proved itself valuable technique for automated vulnerability finding, specially crafted inputs fed programs order trigger crash system. In survey, we link world fuzzing. For list particularities far concerned, perform literature review on techniques proposals, studying applicability and, finally, future research directions pointing out gaps identified review.
