“…Failure analysis is a systematic approach to investigate and comprehend the underlying causes of failures in various systems, products, or processes [26]. The primary objective of failure analysis is to prevent similar failures from happening in the future [12]. Failure analysis is extensively employed to analyse potential safety-related issues in domains where safety is critical.…”

“…While FTA possesses strengths shown in Table 1, such as providing a structured approach for failure analysis, there are also acknowledged weaknesses [12,20]. These include the potential for human error in tree creation, a cumbersome process, lack of support for reusability, and inherent limitations of manual-based system analysis methods.…”

The agricultural industry has the potential to undergo a revolutionary transformation with the use of Internet of Things (IoT) technology. Crop monitoring can be improved, waste reduced, and efficiency increased. However, there are risks associated with system failures that can lead to significant losses and food insecurity. Therefore, a proactive approach is necessary to ensure the effective safety assessment of new IoT systems before deployment. It is crucial to identify potential causes of failure and their severity from the conceptual design phase of the IoT system within smart agricultural ecosystems. This will help prevent such risks and ensure the safety of the system. This study examines the failure behaviour of IoT-based Smart Irrigation Systems (SIS) to identify potential causes of failure. This study proposes a comprehensive Model-Based Safety Analysis (MBSA) framework to model the failure behaviour of SIS and generate analysable safety artefacts of the system using System Modelling Language (SysML). The MBSA approach provides meticulousness to the analysis, supports model reuse, and makes the development of a Fault Tree Analysis (FTA) model easier, thereby reducing the inherent limitations of informal system analysis. The FTA model identifies component failures and their propagation, providing a detailed understanding of how individual component failures can lead to the overall failure of the SIS. This study offers valuable insights into the interconnectedness of various component failures by evaluating the SIS failure behaviour through the FTA model. This study generates multiple minimal cut sets, which provide actionable insights into designing dependable IoT-based SIS. This analysis identifies potential weak points in the design and provides a foundation for safety risk mitigation strategies. This study emphasises the significance of a systematic and model-driven approach to improving the dependability of IoT systems in agriculture, ensuring sustainable and safe implementation.

“…Furthermore, they describe the types of VPNs to be categorized into consumer, enterprise and site-to-site VPNs. Consumer VPNs provide security and privacy of users internet traffic and are typically used to overcome restrictions for example those imposed by internet providers [24][25][26]. On the other hand, enterprise VPNs comprise of connections to enterprise networks for remote users.…”

The recent COVID-19 pandemic has showcased the implications of using virtual private networks (VPNs) as home-working is now common. Establishing the current state of knowledge on VPNs and their processes is vital. This corroborates an up to date understanding on the fundamentals of VPNs and their usage in today’s society; it informs on how to better use VPNs too. Insight into the security issues VPNs face and possible solutions to these allows for the identification of gaps for potential future research. Addressing these gaps would then indicate how to further improve VPNs, making sure VPNs are indeed beneficial to users.
