The advantages offered by these technologies are frequently coupled with serious security issues that are often not properly overseen or even ignored. The IoT threat landscape is extremely wide and complex and involves a wide variety of hardware and software technologies. In this framework, the security of application layer protocols is of paramount importance since these protocols are at the basis of the communications among applications and services running on different IoT devices and on cloud/edge infrastructures. This paper offers a comprehensive survey of application layer protocol security by presenting the main challenges and findings. More specifically, the paper focuses on the most popular protocols devised in IoT environments for messaging/data sharing and for service discovery. The main threats of these protocols as well as the Common Vulnerabilities and Exposures TI - Security of IoT Application Layer Protocols: Challenges and Findings JF - Future Internet DO - 10.3390/fi12030055 DA - 2020-03-17 UR - https://www.deepdyve.com/lp/unpaywall/security-of-iot-application-layer-protocols-challenges-and-findings-CqI0zuQrhf DP - DeepDyve ER -
