<b>Securing the Internet of Things: Comprehensive Analysis, Testing, and Strategies</b>

<p dir="ltr">As IoT devices increasingly become integral parts of our homes, workplaces, and critical infrastructure, their rapid adoption brings both exciting opportunities and significant security challenges. These devices handle sensitive data, making them attractive targets for malicious activities, which can lead to privacy breaches, data theft, and service disruptions.</p><p dir="ltr">Recognizing the urgency of enhanced IoT security, this thesis focuses on the real-world Smart Nursery scenario to highlight potential Network Scanning, Unauthorized Access, Denial of Service (DoS) Attacks, and Impersonation vulnerabilities in the selected IoT devices within a smart nursery setup. By designing specific threat scenarios relevant for smart nursery on the actual security threats users face and exploiting these scenarios using security tools such as Nmap, tcpdump, Metasploit, Wireshark, and additional open-source tools such as Intelx.io, HaveIBeenPwned.com, DNStwist, Phishing Rod, and VulMon to test the security of these devices in a controlled environment. These tools helped to identify open ports, monitor network traffic for anomalies, simulate real-world attacks, and uncover compromised account credentials. They also assisted in detecting phishing attempts, enumerating subdomains, and assessing overall security. This comprehensive testing provided valuable insights into potential vulnerabilities and threats that affect the Smart Nursery and the selected IoT devices.<br>This thesis aims to identify specific security gaps such as unauthorized access, data breaches, and DoS attacks in the context of a smart nursery setup and offer recommendations to protect against the discovered threats and vulnerabilities. Through detailed security testing, specifically tailored threat scenarios analysis, and potential security recommendations, it contributes to the broader effort to create a safer, more secure IoT landscape, particularly for sensitive environments like smart nurseries.</p>
