Developing Smart City security through Upgrade Internet of Things Layers security

Lot devices like connected sensors, lighting, and meters are used in smart cities to collect and analyze data. The cities utilize this information to enhance their infrastructure, public services, and more. A public/private infrastructure must be established in order to execute operations and supply the technologies necessary to protect and secure citizens in order to maintain a secure smart safe city. This contains the following three essential actions: 1) Shared intelligence, communications, and situational awareness. The Internet of Things (IoT) is essentially a network that connects electronic gadgets to the internet, enabling seamless network communication between them. Security is an important issue in the IoT environment, where the protection of data is an urgent process. Every object will be connected to the internet and these objects communicate between each other. Therefore, a new security and privacy problems will appear. This paper introduces several security concepts on each IoT layer. Additionally, illustrates the security goals, challenges and security methods in each layer. Finally, this paper will develop a secure Smart city through improving the IoT layers security.
