Internet of Things (IoT) is a combination of technologies with many applications that attempt to enhance the quality of humans’ life. IoT appliances gather data without human direct interaction and analyse it to be used without complexity. This advantage leads the IoT to become the main key to operate the smart city applications. Most of the large cities are involving IoT to support smart city applications such as traffic control, weather monitoring, or water and electrical services management. However, some IoT appliances gather private and critical data, which turn them into a target for adversaries whom work on exposing this data either for personal gain or perform attacks on the system to damage the city’s infrastructure. There are several challenges in using IoT regarding data confidentiality, integrity, and authentication. Robust security solutions are essential requirements for IoT devices and their applications. Nevertheless, there are some IoT devices certified and secure, but they need to be updated once a breach has been detected or the version became outdated.Within this paper, we provide and discuss some of these challenges related to network layer of IoT architecture, how we can overcome them to ensure confidentiality, integrity, and authentication to prevent potential threats. Additionally, provide directions for future researches that aim to address security issues, and introduce new applications to achieve the goals. In addition, we proposed security frameworks to be standardized for IoT devices.
