FOREWORD
Smart devices are now being commonly used by everyone in their daily lives for routine activities. These smart devices enable us to connect with others (smartphones), have driverless cars (smart cars), secure our buildings (smart locks), remotely control appliances in our homes (smart homes), and remind us to do things and do things for us (smart assistants like Alexa and Siri). At the personal level, wearables enable us to use these smart devices on our bodies and wear them like accessories or embedded in our clothing or implanted in our bodies. For example, we wear smartwatches and fitness trackers to keep track of our physical activities, our heart rate, and our quality of sleep. For healthcare, we use wearables to measure our temperature, blood pressure, breathing rate, blood sugar level, heartbeat rate, and brain activity and monitor our vital signs. Smart devices and wearables have become pervasive, but they need Internet or Network connectivity and Internet of Things infrastructure.
As smart devices, wearables, and implantable technologies get more traction in healthcare, we need to be mindful of their security because of their connectivity to the Internet. For example, pacemakers now have built-in WIFI connectivity for any adjustments that are required in the future. Next-generation cardiac wearables and other implantables will integrate into Wireless Body Area Networks (WBAN). Specialists will sit at their desktops, connect to these implantables via the WIFI, and make adjustments. Such connectivity poses security risks, and these risks are not only monetary losses but also losses of life if the implantables are sabotaged. Therefore, the security issues of these devices through cyber forensics and investigations are thoroughly explored in this edited book. The vulnerability of these devices is mostly during data transmission to the cloud or the owner’s personal device with which it is paired. Blockchain-based security controls are now being implemented with two-factor authentication (2FA) by most device makers to mitigate against such security vulnerabilities.
As lives are at stake, we need to have a foolproof process to investigate and ascertain the intent of the cyber attackers and potential sabotages while gathering evidence to prosecute them and defend the devices from future attacks. The cyber forensics and investigation process is ideal as it allows investigators (depending on which standard you follow) to identify, obtain, process, and analyse data to report about the security incidents that took place to management for mitigation action and authorities for prosecution. As the smart devices are part of a network or connected via a wireless network, network monitoring is possible, and all the cyber security protocols can be applied to these smart devices, logs can be inspected, and all activities monitored for forensics. The cyber forensics and investigation process will encourage the adoption and use of smart devices such as the Internet of Things (IoT), Internet of Everything (IoE), and Internet of Bodies (IoB) to become pervasive. All these devices and things will sense, collect, process, and store huge amounts of data (big data) and will create unprecedented opportunities for us to investigate the evidence through the discipline of cyber forensics.
This book on cyber forensics and investigation on smart devices is a timely publication as we undergo digital transformations. Smart devices, wearables, and implantables are getting cheaper, powerful, and are able to handle many processes with network connectivity. With the proliferation of Internet of Things (IoT) devices, the attack surface area has dramatically increased for hackers and the threat surface area has significantly increased for cyber security specialists. This book covers the architecture, deployment problems, applications, data processing, storage, and review of Internet of Things (IoT) protection and privacy problems in a cloud-based approach. The main idea behind this book is to give a practical guide to readers that will cover the advanced tools and techniques used in the domain of cyber forensics and investigation. I hope the readers find the book inspiring and gain a working knowledge of cyber security issues facing smart devices and the mitigation solutions that can be applied to prevent breaches. It is evident that smart devices will become ubiquitous and will become indispensable. The best we can do is learn to live with smart devices by identifying cybersecurity issues and mitigating them.

Smart Home Forensics
Lokaiah Pullagura1,*,Nalli Vinaya Kumari2,Hemanta Kumar Bhuyan3Abstract
The Internet of Things (IoT) has unquestionably exploded into the forefront of everyone's lives, whether they realise it or not. Internet of Things (IoT) technology is now used in medical devices, transportation, and even in our homes. Devices such as these have the ability to access a great deal of personal information. Because of their diminutive size, these devices have made insufficient efforts to build security into their design. Sensors, cameras, and lights are all examples of Internet of Things (IoT) devices that can be used to automate daily tasks around the home. Smartphones and speakers can be used as remote controllers to operate these gadgets. A smart home's IoT devices collect and process data on motion, temperature, lighting control, and other variables, and they store a wider range of data from more diverse users. A wide variety of smart home devices can make extracting meaningful data difficult because of their differing data storage methods. Data from a variety of smart home devices, as well as data that can be used in digital forensics, must be collected and analysed. Google Nest Hub and Samsung Smart Things are the primary sources of forensic smart home data that will be analysed in this study. As a result, we analysed the smart home data collected using companion apps, web interfaces, and APIs to find information that was relevant to our investigation. Various types of data collected by smart homes are also discussed in the paper, and they can be used as crucial evidence in certain forensic cases. IoT devices in a smart home can be hacked, and we'll investigate how, what data can be recovered, and where it resides after it has been hacked as part of our investigation.
1. INTRODUCTION
Home owners can benefit from new internet-enabled devices that are easy and safe to use. The introduction of new internet-enabled devices, particularly at home, is seen as a convenient and safe way to enhance human life. A home's systems can be controlled, monitored, and even entertained using Internet-enabled gadgets. A “smart house” is comprised of gadgets like this one. Throughout this paper, we'll refer to these gadgets as the “Internet of Things” (IoT). A whopping $53 billion could be generated by smart home gadgets like smart plugs and switches, smart speakers, and surveillance camera systems by 2022 [1, 2]. Despite the rapid uptake of IoT devices in the home, there have been reports of cyber-attacks and privacy concerns [3, 4]. Avast [5] estimates that one out of every two Internet of Things (IoT) devices in smart homes is vulnerable to cyberattacks. IoT devices are ubiquitous in today's smart homes, making security and privacy a top priority. An estimated 75% of people say they don't trust their IoT devices when it comes to handling and sharing their personal information [6]. Smart homes have become increasingly popular due to their convenience and ability to automate various aspects of daily life. However, with this increased reliance on technology, there is a growing need for forensic investigation of smart homes in cases of security breaches, theft, or other criminal activity. Smart home forensics involves the application of forensic techniques to digital devices and networks that make up a smart home, including the analysis of data from devices such as smart speakers, thermostats, security cameras, and home automation systems, as well as the examination of network traffic and other digital evidence. Smart homes consist of various interconnected devices and systems that are controlled by a central hub or app [6]. These devices can include smart TVs, home security systems, smart thermostats, and even smart refrigerators. They are designed to make life easier and more convenient for users, but they can also create vulnerabilities that can be exploited by hackers and other malicious actors. Smart home forensics involves the use of forensic techniques to analyze digital devices and data in order to identify evidence of unauthorized access, data theft, or other criminal activity. This may involve the collection and analysis of data from various smart devices, such as security camera footage, device logs, and other digital data. Forensic investigators may also examine network traffic to identify unusual activity and potential sources of attacks. One of the challenges of smart home forensics is the lack of standardization in smart home devices and protocols. Different manufacturers use different technologies and standards, making it difficult to create a unified approach to forensic investigation. Additionally, the complexity of smart home systems can make it difficult to identify and analyze potential sources of evidence. Another challenge is the need for specialized tools and techniques for forensic analysis. Traditional forensic tools may not be sufficient for analyzing smart home devices and data, and investigators may need to use specialized software and hardware tools to extract and analyze data from these devices. Despite these challenges, the importance of smart home forensics is likely to continue to grow as more people adopt smart home technology. Forensic investigators and other professionals will need to develop the necessary skills and knowledge to effectively investigate these types of cases and identify and prevent potential security threats [7]. An in-depth examination of forensic investigations into smart homes and the use of a laboratory to look into potential threats is provided. Both methods are described in great detail. The data from the IoT lab will assist us in answering the following research questions: There are a number of smart home devices and smartphone apps that can provide valuable information. How secure are these smart home gadgets when it comes to personal data? Does the security of these smart home devices need to be improved? For smart home devices, what are the best ways to collect and analyse data? These smart home appliances are exchanging what kinds of personal information. It's laid out like this: Section 2 provides background information on IoT forensics and Smart Home devices. Section 3 and Section 4 describe our smart home lab and the digital forensic investigative process. Threats to smart homes are discussed in Section 5 of this document. Finally, Section 6 brings an end to all of our hard work.
