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.

Lightweight Encryption

Abstract: With the development of mobile devices and the advent of smartphones, the Internet has become part of everyday life. Any category of information about weather, flight schedule, etc. it is just a click away from the keyboard. This availability of data has led to a continuous increase in connectivity between devices, from any corner of the world. Combining device connectivity with systems automation allows the collection of information, its analysis and implicitly decision-making on the basis of information. Their introduction and continued expansion of devices that communicate in networks (including the Internet) have made security issues very important devices as well as for users. One of the main methodologies that ensures data confidentiality is encryption, which protects data from unauthorized access, but at the cost of using extensive mathematical models. Due to the nature of IoT devices, the resources allocated to a device can be constrained by certain factors, some of which are related to costs and others to the physical limitations of the device. Ensuring the confidentiality of data requires the use of encryption algorithms for these interconnected devices, which provide protection while maintaining the operation of that device. The need for these types of algorithms has created conditions for the growth and development of the concept of lightweight encryption, which aim to find encryption systems that can be implemented on these categories of devices, with limited hardware and software requirements. The paper proposes a lightweight cryptographic algorithm implemented on a microcontroller system, comparing its performances with those of the already existing system (based on x86).

Search For Information

Today, the internet has become the most used tool for delivering information. Through the internet, people can search for information by freely accessing a web page. This freedom of access often raises security issues in the website provider's internal network. These security issues can be in the form of misuse of information, threats, and other attacks on the provider's internal network. Based on these conditions, a technique is needed to protect important data on the website owner's server from various attacks. In this research, a Honeypot security system has been implemented using Dionaea and Kippo in the Demilitarized Zone to increase the security of a network. The methodology of this research is Waterfall Model for software engineering. The system that has been built is able to detect, take action, record attack logs and display them in the form of a website in real time.

Malicious Intent

The growing pervasiveness of the internet and the rise of social media have revolutionised how individuals communicate and interact with one another. Serving as an effective conduit for communication, these technological advancements have also been exploited by individuals with malicious intent (e.g., criminals, violent extremists). As the world witnesses an upward trend of such crime and security concerns in the online sphere, it places the ‘responsibility' on intelligence and law enforcement agencies to respond with the appropriate technological interventions. Thus, this article will discuss how digital footprints can be leveraged to identify potential security threats, particularly for crime and security issues that will result in negative repercussion at the national level, such as acts of violent extremism and hate crimes.

Design Challenges

Cloud computing has recently emerged as a new paradigm of computing for hosting and delivering services over the Internet. It replaces computing as a personal commodity by computing as a public utility. It is attractive solution to business owners as it eliminates the requirement for users to plan ahead for provisioning, and allows enterprises to start from the small and increase resources only when there is a rise in service demand. However, despite the significant benefits, these technologies present many challenges including lack of security. The chapter presents an advanced survey focusing on cloud computing concept. It highlights its key concepts and presents a physical architecture of this environment. Finally, the chapter defines virtualization technology as a factor for cloud computing surge and discuses security issues that damage these systems. The aim of this chapter is to provide a better understanding of the design challenges of cloud computing.

Elderly population in the Asian countries is increasing at a very fast rate. Lack of healthcare resources and infrastructure in many countries makes the task of provding proper healthcare difficult. Internet of things (IoT) in healthcare can address the problem effectively. Patient care is possible at home using IoT devices. IoT devices are used to collect different types of data. Various algorithms may be used to analyse data. IoT devices are connected to the internet and all the data of the patients with various health reports are available online and hence security issues arise. IoT sensors, IoT communication technologies, IoT gadgets, components of IoT, IoT layers, cloud and fog computing, benefits of IoT, IoT-based algorithms, IoT security issues, and IoT challenges are discussed in the chapter. Nowadays global epidemic COVID19 has demolished the economy and health services of all the countries worldwide. Usefulness of IoT in COVID19-related issues is explained here.

There are various emerging areas in which profoundly constrained interconnected devices connect to accomplish specific tasks. Nowadays, internet of things (IoT) enables many low-resource and constrained devices to communicate, do computations, and make smarter decisions within a short period. However, there are many challenges and issues in such devices like power consumption, limited battery, memory space, performance, cost, and security. This chapter presents the security issues in such a constrained environment, where the traditional cryptographic algorithms cannot be used and, thus, discusses various lightweight cryptographic algorithms in detail and present a comparison between these algorithms. Further, the chapter also discusses the power awakening scheme and reference architecture in IoT for constrained device environment with a focus on research challenges, issues, and their solutions.

It is estimated that over 1 billion people now have access to the Internet. This unprecedented access and use of Internet by individuals around the world, however, is accompanied by malicious and mischievous activities online. With the traditional crimes such as fraud, identity theft, and harassment now being committed with the use of the Internet, and networked home computers being exploited to carry out attacks such as denial of service, spamming, phishing and virus/worm propagation, it has become important to investigate security and privacy issues as they pertain to individual Internet users. To date very little is known about what characteristics of internet users affect their computing and on-line behaviors as they relate to security online. While some attention has been paid to understand the security issues affecting corporations, research investigating security issues as they relate to home users is still in infancy. Drawing from disciplines such as criminology, sociology, consumer fraud, and information security, this study seeks to find the role of computing skills and computer training, social influence, and gender on person’s vulnerability to Internet crimes. Our findings are significant and shed light in this important area of Internet crime contributing to the information security literature.
