Research studies have led to the implementation of rules that are crucial for system security and the protection of private information [14; 20; 21]. The vulnerabilities of the IoT architecture were identified, such as the heterogeneity of smart devices and their Internet interaction, which can potentially expose a home's security to intruders [22; 23; 24]. Preventing future threats and identifying solutions for possible system attacks are the main concerns of these studies. [PERSON] and [PERSON] [25] offer an extensive examination of the security challenges facing smart-home systems. This research delves into the architecture of smart homes, identifying six natural and contextual features, and discusses the dichotomy of \"spears\" (cyber-attack methods) versus \"shields\" (countermeasures). The paper highlights various security frameworks and evaluation technologies and discusses the integration of smart-home technology with other fields, such as blockchain, cloud computing, and artificial intelligence. The authors suggest that future research should focus on unifying architecture, addressing resource limitations, managing fragmentation, and enhancing code and firmware security. The survey also emphasizes the importance of prioritizing security in smart-home research over the commercialization process to ensure the development of robust and reliable systems. [PERSON] et al. [26] provide a comprehensive overview of how smart-home technologies contribute to security. The authors explore a range of smart-home functionalities that enhance the safety of residents, including the detection, identification, and response to potential threats. They offer a comparative analysis of both existing commercial products and academic research in the field. Key contributions include the discussion on sensingmechanisms within smart homes that detect anomalies or security breaches, assessing the nature and severity of these threats, and the automated response systems designed to manage these threats effectively. [PERSON] et al. [27] thoroughly examine the integration and implications of IoT technologies within the home. The paper addresses how devices are becoming ubiquitous in households, expanding the IoT landscape but also escalating security vulnerabilities. It highlights the significant increase in IoT-device deployment and the corresponding security expenditures forecasted to manage associated risks. The study details various IoT components, including sensors, actuators, and network protocols, emphasizing their roles in enhancing connectivity but also in increasing potential security breaches. The authors discuss current security challenges, such as the susceptibility to Distributed Denial of Service (DDoS) attacks and the ease of unauthorized access due to weak authentication practices. The paper concludes with a call for robust security measures embedded within the IoT development phase and continuous updates to safeguard a system against evolving cyber threats, aiming for a secure integration of IoT into daily life and infrastructure. Researchers are particularly focused on identifying solutions for intrusion-detection systems (IDSs) for smart homes [28; 29], which are critical for protecting the security of the system. The quality of service of the network is also a major issue that must be addressed in order to ensure system security. Software-Defined Networks (SDNs) offer scalability of the system, but they also increase the system's vulnerability to attacks. Researchers are tasked with developing solutions that protect the security protocols [30; 31; 32] of Routing Protocol for Low-Power and Lossy Networks (RPL) and IPv6 over Low-Power Wireless Personal Area Networks (6 LowPan) from possible attacks, while maintaining a secure network and high quality of service (QoS). In addition to a high QoS value, the IDS performance must remain sufficient, with low energy consumption and a low data processing time, while also ensuring an immediate response.
