Abstract: The Internet of Things (IoT) is an emerging technology that has gained widespread attention across industries due to its potential to revolutionize how we interact with the world. The central goal of IoT is to enable seamless communication between physical objects of all sizes, allowing them to exchange data autonomously over the Internet without human intervention. These devices are equipped with sensors to collect data and actuators to take actions based on that data, driving intelligent decision-making processes. IoT has already had a significant impact in numerous fields, such as home automation, smart cities, healthcare, agriculture, and manufacturing, as well as the development of wearables and smart devices. It has become a cornerstone for innovation, enabling the creation of smart environments that improve efficiency and convenience for individuals and businesses alike. However, the widespread adoption of IoT also introduces critical challenges, particularly concerning connectivity, compatibility, longevity, and, most importantly, security and privacy. The inherent heterogeneity and dynamism of IoT systems complicate the effective management of security risks, with sensitive data being vulnerable to various cyber threats. This paper reviews existing security frameworks and assessment standards in the context of IoT, highlighting the challenges in securing IoT-based smart environments. It emphasizes the importance of addressing these security concerns to ensure the continued growth and safe adoption of IoT technologies.
