The term cybersecurity refers to an environment capable of protecting digital devices, networks and information from unauthorized access and preventing data theft or alteration. It is composed of a collection of carefully crafted techniques, processes, and practices to protect sensitive information and deterring cyber-attacks. In the recent period, the domain of cybersecurity has undergone rapid growth in response to the increasing cyber threats. Cybersecurity includes important tactics that help protect the digital environment, which are firewalls, encryption, secure passwords, and threat detection and response systems. Employees must be trained on these tactics. This article will discuss the five most pressing challenges facing the cybersecurity industry today that must be taken into account by businesses, organizations, and individuals in order to secure their confidential data from cybercrime. The conclusion of the article highlighted the significance of growing awareness about cybersecurity risks in order to effectively handle digital environments and protect them from any electronic threats.

“…In that case, they can steal everything or erase all money from the targeted system or account. Moreover, since it is a decentralized system, thus there is no way to recover stolen currency from anywhere (Ramos et al 2021 ; Zetzsche et al 2020 ; Casino et al 2019 ).…”

“…Upgradation risk is the next to fall in this category. Many times, attacks or controversial situations (community conflict) may lead to the forking of a cryptocurrency (Ramos et al 2021 ). Forking is the split of the blockchain into two separate branches following a change in the rules of the system.…”

Decentralized finance is disrupting the financial ecosystem through innovative, transparent, and interoperable financial solutions. Based on distributed ledger technology, decentralized finance is a nascent and rapidly evolving area. Decentralized finance protocols are witnessing a perfect storm (in terms of growth). However, this emerging area needs sober consideration as these financial technologies possess unique risks for users, makers, regulators, and other stakeholders. The current research aims to identify and prioritize risks in decentralized finance. The present study conducted an extensive survey of the literature to identify various risks involved in decentralized finance. For empirical analysis, the study collected data from 90 experts. A fuzzy analytical hierarchical process (F-AHP) was applied to prioritize various risks in decentralized finance. Pairwise comparison and weights of all the criteria and sub-criteria revealed that technical risks are the most significant ones, followed by legal, regulatory, and financial risks. Among the sub-risks, financial risks are at the highest level, followed by smart contract risks and transaction risks. The outcomes of this research have several implications for regulators, policymakers, entrepreneurs, technologists, and practitioners. These stakeholders can focus on these vulnerabilities and offer more sustained solutions in the future.

“…This attack, if successful, can lead to fraudulent transactions in the blockchain. A forking attack is particularly hazardous for users of personal IoT devices because if the forking attack is a hard attack, it is not reversible [111]. Further security concerns of blockchain have been highlighted by the authors of [112] who identified that blockchain on a wireless network that shares database access with the network is prone to a range of security threats that can result in cybercriminals emulating a hidden node.…”

The growth in the use of small sensor devices, commonly known as the Internet of Things (IoT), has resulted in unprecedented amounts of data being generated and captured. With the rapidly growing popularity of personal IoT devices, the collection of personal data through such devices has also increased exponentially. To accommodate the anticipated growth in connected devices, researchers are now investigating futuristic network technologies that are capable of processing large volumes of information at much faster speeds. However, the introduction of innovative network technologies coupled with existing vulnerabilities of personal IoT devices and insufficient device security standards is resulting in new challenges for the security of data collected on these devices. While existing research has focused on the technical aspects of security vulnerabilities and solutions in either network or IoT technologies separately, this paper thoroughly investigates common aspects impacting IoT security on existing and futuristic networks, including human-centric issues and the mechanisms that can lead to loss of confidentiality. By undertaking a comprehensive literature review of existing research, this article has identified five key areas that impact IoT security for futuristic next generation networks. Furthermore, by extensively analysing each area, the article reports on conclusive findings and future research opportunities for IoT privacy and security for the next generation of network technologies.
