In recent years, the number of Internet of Things (IoT) devices has expanded fast, transforming various industries such as healthcare, manufacturing, and transportation, and delivering benefits to both individuals and industries. However, the increased use of IoT devices has exposed IoT ecosystems to a slew of security risks and digital forensic issues. This thesis investigates the most common IoT security dangers and attacks, as well as students' understanding of them and mitigation techniques, as well as the key issues involved with IoT forensic investigations. In this thesis, a mixed-method approach is used, combining a literature review and a survey investigation. The poll measures students' understanding of IoT security threats, mitigation approaches, and perceptions of the most effective ways to improve IoT security. In addition, the survey underlines the importance of user training and awareness in minimizing IoT dangers, highlighting the most effective strategies, such as stronger regulations and increased device security by manufacturers. The literature review provides a complete overview of the most popular IoT security risks and attacks, including malware, malicious code injection, replay attacks, Man in the Middle (MITM), botnets, and Distributed Denial of Service (DDoS). This paper also emphasizes the definition and process of digital and IoT forensics, the significance of IoT forensics, and various data sources in IoT ecosystems. The key issues of IoT forensics and how they affect the efficiency of digital investigations in the IoT ecosystem are thoroughly investigated. Overall, the findings of this study contribute to ongoing research to improve IoT device security, emphasize the necessity of greater awareness and user training, and address the issues of IoT forensic investigations. 

This report will discuss the impact of COVID-19 on cybersecurity. This report also discusses cyber threats in the home office, the healthcare and public health (HPH) sector in attackers’ sight, and the rise of COVID-themed phishing attacks targeted towards remote workers and internet users. Tips on mitigating cyber risk will also be touched upon. This study utilizes surveys conducted to identify the effects this ongoing pandemic has had on businesses and people. 

This report will discuss biometric usage and its risks across different age groups in a time when biometric technologies continue to grow. This report will also discuss how different age groups utilize biometric systems, the advantages and disadvantages of these systems, and the affect it has on the identified population. Issues on biometrics on an ageing population will also be touched upon. This study utilizes surveys conducted to identify and compare the different ways the population uses biometrics and identify the risk associated with distinct usage.
