Abstract : IoT security is essential to prevent data breaches, as most IoT devices lack built-in security mechanisms. These devices often go undetected by traditional cybersecurity systems, transferring unencrypted data over the internet, which leaves them vulnerable to attacks. IoT security refers to the measures designed to protect connected devices and systems from unauthorized access, cyberattacks, and other security threats. This encompasses securing the devices themselves, safeguarding data transmission, and fortifying the underlying network infrastructure. IoT security faces several challenges, including the vast number of devices with varying security levels, the complexity of interconnected networks, and the growing sophistication of cyber threats. This research study emphasizes the importance of enhancing IoT security. It examines the most common communication technologies—Bluetooth, Wi-Fi, and LTE—and evaluates the safeguards available for them, focusing specifically on Wi-Fi technology in this article. The EBIOS risk assessment method is employed to identify potential vulnerabilities and threats within the Wi-Fi ecosystem. The ultimate objective of this work is to highlight and mitigate security risks associated with using Wi-Fi in IoT environments. The broader goal of IoT security is to ensure the confidentiality, integrity, and availability of data and systems while maintaining the functionality and usability of connected devices.

Keywords : IoT, Cyber-attack, Bluetooth, Wi-Fi, LTE, IoT Security, Data Breach, Network Infrastructure, EBIOS Technique, Vulnerability Assessment.
