Abstract: The Internet of Things (IoT) represents a ubiquitous modern technology that enables devices to communicate with each other and exchange data via the internet. Given its increasingly widespread application in smart homes, industry, and critical infrastructure, the security of IoT devices has become a crucial issue. Due to their connectivity and often insufficient levels of protection, IoT devices represent a significant target for various forms of cyberattacks. The aim of this paper is to analyze the fundamental threats related to the security of IoT devices, identify vulnerabilities, and present potential protection methods and best practices in the field of cybersecurity. As part of the practical section of this paper, a security test was conducted on a smart WiFi camera to demonstrate potential weaknesses and protection methods through a concrete example. This paper provides an overview of current security threats, security testing methods, and proposals for technical and organizational protection measures in accordance with relevant security standards.
