Smart city security architecture in iot

The massive scale of To address the growing fear and uncertainty out there surrounding the IoT security architecture, our IoT security research practice teamed up with the IoT Security company help companies implementing IoT double-check that their solutions are built secure. Part 1 of this 3-part security-focused blog series presents an introduction into the overall IoT security architecture and highlights six key principles as explained by Developing secure end-to-end IoT solutions involves multiple levels that fuse together important IoT security architecture features across four different layers: Device, Communications, Cloud, and Lifecycle Management. A. Secure Device Layer The device layer refers to the hardware level of the IoT solution i.e., the physical “thing” or product. ODMs and OEMs (who design and produce devices) are increasingly integrating more security features in both their hardware and software (that is running on the device) to enhance the level of security on the device layer. Important IoT security architecture features: • Some manufacturers are introducing chip security in the form of TPMs (Trusted Platform Modules) that act as a root of trust by protecting sensitive information and credentials (i.e., not releasing encryption keys outside the chip). • Secure booting can be used to ensure only verified software will run on the device. • Even physical security protection (e.g., full metal shield covering all internal circuitry) can be employed to guar...

Smart city can be taken as the biggest implementation of Internet of things (IoT) applications. Smart city technologies promote cloud-based and IoT-based services in which real-world user interfaces use smart phones, sensors, RFIDs, etc. The IoT ecosystems cannot properly communicate between them. So it needs a bridge between them to fill the global common approach. Implementation of this can be done with the help of information and communication technologies (ICT) which may result in enhancing quality, interconnection, and the performance of various urban services. It highlights the need for cloud computing and IoT technologies and both have a major impact on how we build and deploy smart applications for it. There are still numerous difficulties that remain with regard to its deployment due to its varying requirements. In this paper, authors tried to converge the two domains that are cloud computing and IoT for smart city application deployment and also present the identified security threat types and their countermeasures in the context of smart city.

In this paper, we study the security aspects of the new 5G-IoT architecture, which is recently developed by this research team. We classify potential security attacks at each layer of the 5G-IoT architecture. As the main contribution of this work, we propose a security taxonomy for the 5G-IoT architecture in the context of smart city applications. This taxonomy consists of five layers to confront the studied attacks and to protect the privacy of clients. The number of layers is selected according to the types of attacks where each attack type affects a particular layer of the 5G-IoT architecture. References • A. Whitmore, A. Agarwal, and L.

The Internet of Things (IoT) presents itself as a promising set of technologies to support a wide range of applications that aim to improve the quality of life of humans. IoT aims to simplify the way that users receive information providing a unique way of bringing them close to the source of information, hiding the complexity of knowing who or what one should ask to get that information. For this reason, IoT has become a key enabler for smart city applications, and municipalities are very interested to invest in IoT for providing advanced applications to their citizens, who might not be at all familiar with Information and Communication Technologies (ICT). It is quite common in the last few years that large cities are forming strategic agendas for becoming “smarter” through IoT technologies. Their main goal is to build IoT-based infrastructures that can be reused for supporting a plethora of smart city applications, for, i.e., monitoring the weather conditions, the traffic, the citizens’ needs, or for managing the wastes, the city waters, etc. All these applications are indeed very promising for making the cities smarter, but as they are becoming more and more mainstream, they are turning into attractive targets for attackers that aim to exploit the constrained nature of IoT devices toward stealing personal data or performing physical attacks on critical infrastructures. IoT deployments pose severe challenges with regard to ensuring the security of the overall system and ...

Today, some cities around the world have tended to use new technologies and become smart city. New technologies improve the quality of citizens’ life. However, the use of any technology raises new issues and challenges. In a smart city, the vulnerable action of an individual or organization can put the entire city at risk. Due to the reliance of various components of smart cities on information and communication technology, cyber-security challenges (such as information leakage and malicious cyber-attacks) in this field affect smart cities behavior. Therefore, in order to respond to the enthusiastic acceptance of global smart city technologies, cyber security must develop in same direction. The aim of this paper is survey and discus on explanation of cyber security, smart cities, and survey of available relevant literature on security in that technology. For this purpose, the present study focuses on the four main components of a smart city, i.e. smart grid, Smart building, Smart transportation system, and Smart healthcare. In particular, summary of two deep learning method and cyber-security programs as well as technology correlation in smart cities are discussed. Furthermore, effective functional solutions in maintaining cyber-security and user privacy in smart cities are explained. The next progress trends of smart city with cyber security are described. Solutions need to be devised to address each of the security issues. The research in this study showed that meeting t...

In the twenty-first century, so many technological paradigms emerged as the result of the technological advancement of information and communication technology (ICT). Many of the technologies were used as an aid for fulfilling human needs and mitigating many of the problems associated with the environment and making everyone connected. In order to mitigate the problem of rapid urbanization smart city concept has emerged and it is being used to streamline the functions of urban cities and make the lives of citizens more easy and convenient. In a typical smart city context, citizens are already interconnected via smart mobile devices and wearable devices. The hospitals, vehicles, houses, traffic surveillance systems, public places, and other social systems in the city are all connected over the Internet, which is known as the Internet of Things (IoT). This will contribute to unprecedented changes in the condition of life in the city. In public care, public safety, emergency management, and disaster recovery, these pervasive systems which are linked through the Internet can assist citizens with greater benefits. The world is now witnessing a boom of smart cities. Although smart cities have many advantages, such as creating new economic and social possibilities, there are many challenges, such as security and privacy. These security and privacy challenges include unauthorized access to information and attacks that cause physical interruptions in the provision of city services....

Now’s the Time for Smart Cities Modern cities continue to grow at a rapid pace, with 55 percent of the world’s population living in urban areas today and a projected 13 percent increase to that number by 2050. 1 Cities around the world are being challenged to provide tangible and equitable economic, social, and environmental benefits for their citizens. They must also provide better quality and more sustainable services, improve public safety, address congestion and environmental issues, reduce costs, and promote local economic competitiveness. Scaling existing infrastructure and human resource-intensive processes is cost prohibitive, unmanageable, and unsupportable, so cities are looking to technological solutions to alleviate these pressures. As population has grown, technology has taken unprecedented strides. With the introduction of Internet of Things (IoT) devices, edge computing, machine learning, artificial intelligence (AI), and 5G communications networks, the technological tools needed are now available, and transitioning to a smart, technology-supported city is now possible. Embedded smart city technologies (sensors, cameras, and edge computing) can now provide near real-time awareness of issues requiring attention, and data collected and analyzed from these devices can be used to optimize city operations. Smart city solutions can improve basic services, enhance public safety, increase sustainability, and inform planning and policy making. They can also be used t...
