Firstly, we describe the crucial components of the IoT (i.e., architectures, standards, and protocols) in the context of security at perception layer followed by IoT security requirements. We shall use the generic 5-layer IoT protocol stack (architectural diagram presented in Figure 2) for both the fog and cloud architectures. It is useful in most of IoT applications. It was developed by IBM. MQTT runs over the TCP/IP model. His research interest includes mobile and wireless networks, Internet of Things, Software Defined Networking, Edge computing, and Information Security. Application layer protocols founded on TCP and UDP solve the communication challenges faced in an IoT project. He completed his MS degree in Security Technologies and Applications from University of Surrey, UK, in 2010, and has passed his PhD from University of Bedfordshire, UK in 2013. This layer involves the protocols related to communication between the devices in IoT network. Anytime, Anywhere and Anyone 7) IoT uses HTTP protocol in the _____ layer. Data at rest stored in the cloud must be encrypted as well to mitigate risks of exposing sensitive information to intruders. This survey addresses a set of application layer protocols that are being used today for IoT, to affirm a reliable tie among objects and things. This protocol collects the data from the devices and forwards to the network. For reliable and secure transmission over UDP confirmable messages are used and the responses can be in the form of acknowledgment. Application 'Denial of Service' is a method of attack using interconnected PC or devices. The general-purpose protocols like CDMA, WAP, etc are not suitable for this specific IoT technology. It is designed to enable simple, constrained devices to join IoT through constrained networks having low bandwidth availability. Degree College, Landi Kotal and M.S.c Computer Science degree from Institute of Management Sciences, Peshawar, in 2010 and 2013 respectively. Perception layer. It also … The dealer/broker enables the safety connection between the subscriber and publisher. Business layer: it manages the whole IOT system, including applications, business and profit models, and users privacy. Security properties concluded authentication, confidentiality, integrity, freshness, availability, communication security, non-repudiation and access control. Moreover, IoT application layer protocols use HTTP to provide web service to end users in application layers. And the few regular protocols like Bluetooth, WiFi, ZigBee, NFC, Cellular, Long ranged WAN and RFID are not discussed here. network layer. This survey paper proposes a novel taxonomy for IoT technologies, highlights some of the most important technologies, and profiles some applications that have the potential to make a striking difference in human life, espec… Data originates in the device layer and passes through the gateway layer before entering the cloud where the IoT platform layer resides. He received his MSc degree in 2005 from Hazara University Manshera, Pakistan and MS degree in 2008 in Computer System Engineering from GIK Institute, Topi. This was developed by John Hara from JP Morgan Chase, London. Ihsan Ali is currently a PhD Student at the Faculty of Computer Science and Information Technology, University of Malaya.
