Security Of Iot

The Internet of Things is taking hold in our everyday life. Regrettably, the security of IoT devices is often being overlooked. Among the vast array of security issues plaguing the emerging IoT, we decide to focus on access control, as privacy, trust, and other security properties cannot be achieved without controlled access. This article classifies IoT access control solutions from the literature according to their architecture (e.g., centralized, hierarchical, federated, distributed) and examines the suitability of each one for access control purposes. Our analysis concludes that important properties such as auditability and revocation are missing from many proposals while hierarchical and federated architectures are neglected by the community. Finally, we provide an architecture-based taxonomy and future research directions: a focus on hybrid architectures, usability, flexibility, privacy, and revocation schemes in serverless authorization.

The Internet Of Things

Cloud computing has significantly enhanced the growth of the Internet of Things (IoT) by ensuring and supporting the Quality of Service (QoS) of IoT applications. However, cloud services are still far from IoT devices. Notably, the transmission of IoT data experiences network issues, such as high latency. In this case, the cloud platforms cannot satisfy the IoT applications that require real-time response. Yet, the location of cloud services is one of the challenges encountered in the evolution of the IoT paradigm. Recently, edge cloud computing has been proposed to bring cloud services closer to the IoT end-users, becoming a promising paradigm whose pitfalls and challenges are not yet well understood. This paper aims at presenting the leading-edge computing concerning the movement of services from centralized cloud platforms to decentralized platforms, and examines the issues and challenges introduced by these highly distributed environments, to support engineers and researchers who might benefit from this transition.

Security Of Iot

The Internet of Things (IoT) is rapidly changing our society to a world where every “thing” is connected to the Internet, making computing pervasive like never before. This tsunami of connectivity and data collection relies more and more on the Cloud, where data analytics and intelligence actually reside. Cloud computing has indeed revolutionized the way computational resources and services can be used and accessed, implementing the concept of utility computing whose advantages are undeniable for every business. However, despite the benefits in terms of flexibility, economic savings, and support of new services, its widespread adoption is hindered by the security issues arising with its usage. From a security perspective, the technological revolution introduced by IoT and Cloud computing can represent a disaster, as each object might become inherently remotely hackable and, as a consequence, controllable by malicious actors. While the literature mostly focuses on the security of IoT and Cloud computing as separate entities, in this article we provide an up-to-date and well-structured survey of the security issues of cloud computing in the IoT era. We give a clear picture of where security issues occur and what their potential impact is. As a result, we claim that it is not enough to secure IoT devices, as cyber-storms come from Clouds.

Security Of Iot

IoT or the Internet of things refers to all the physical devices connected to the internet. IoT consists of computing devices that are web-enabled and have the capability of sensing, collecting, and sending data. IoT provides the ability to remote control appliances and has many more applications. Since IoT is becoming a big part of society, it is necessary to ensure that these devices provide adequate security measures. This paper discusses various security issues in IoT systems like threats, vulnerabilities and some countermeasures which can be used to provide some security. Developing a secure device is now more important than ever, as with the increase in digitization, much of a user’s data is available on these devices. Securing data is a primary concern in any system, as internet-enabled devices are easier to hack. The idea of this paper is to spread awareness and improve the security of IoT devices.

In recent times, the number of internet of things (IoT) devices/sensors increased tremendously. To support the computational demand of real-time latency-sensitive applications of largely geo-distributed IoT devices/sensors, a new computing paradigm named fog computing has been introduced. In this chapter, the authors will introduce fog computing, its difference in comparison to cloud computing, and issues related to fog. Among the three issues (i.e. service, structural, and security issues), this chapter scrutinizes and comprehensively discusses the service and structural issues also providing the service level objectives of the fog. They next provide various algorithms for computing in fog, the challenges faced, and future research directions. Among the various uses of fog, two scenarios are put to use.

Purpose The purpose of this study is to categorize network neutrality according to its issues under debate and assess the state of the debate based on such organization. In addition, the study discusses the reasons that network neutrality is so difficult to solve and the future research directions that would do so. Design/methodology/approach This study presents a critical review of the current network neutrality issues and summarizes the economic background of each position in the debate. The relevant literature is organized by issue to examine the reasons that the network neutrality debate is so difficult to solve and determine the further study required to solve it. Findings An analysis of the relevant literature suggests that the proponents and opponents of network neutrality disagree on the best methods of developing the Internet. Therefore, future research and regulatory and practitioners’ applications would greatly benefit from a comprehensive review of that literature. Originality/value Network neutrality regulation is receiving increased attention because the development and significant influences of the Internet are becoming more apparent.

Online Reputation

Some firms and industries were not willing to take full advantage of the internet and its endless opportunities, mainly because they rather focused on the inherent risks and challenges. However, when taking into consideration the specificities of the connected generation, the question is not anymore whether to go online or not, but rather to understand how, when, and where, especially in a luxury context. More specifically, the digital natives represent tomorrow's customers. This new market segment represents a main reason for luxury firms to adopt online strategies. Still, further analysis is needed to uncover the main objectives when firms decide to engage in digital activities. The authors herein investigate the concept of e-reputation. The authors expand on their initial study that focused on brand image and social media as determinants of online reputation. Recommendations and future research directions are suggested.

The Impact

New opportunities and challenges are emerging thanks to the growing Internet importance and social media usage. Although practitioners have already recognized the strategic dimension of e-reputation and the power of social media, academic research is still in its infancy when it comes to e-reputation determinants in a social networks context. A study was conducted in the sports setting to explore the impact of social networks on the sportspeople's e-reputation. Whereas the study emphasized (1) the influence of social networks' perception on the sportspeople's e-reputation, and the neutral roles of (2) the motives for following sportspeople online, and (3) the negative content on the Internet, additional insights are formulated on maintaining, restoring and managing e-reputation on social networks. Finally, future research directions are suggested on the role of image to control e-reputation.
