Cybersecurity has become increasingly important and critical as the world grows more interconnected and the Internet of Things (IoT) establishes itself as a global reality. Today, most embedded devices operate as IoT components, making their protection a priority. Over time, several international standards have been developed to define best practices for cybersecurity in this field, and organizations are mostly required to comply with them. After an in-depth study of the principal standards and best practices, this thesis focus shifted on the analysis of vulnerabilities in a custom embedded device. Starting from a static vulnerability assessment, targeted tests were performed, and based on the results improvements were subsequently introduced to enhance the device’s security posture.
