Analýza zranitelností IoT zařízení v domácnostech

This bachelor thesis focuses on the security analysis of consumer IoT devices in smart home environments, with an emphasis on IP cameras with remote access. The aim of the thesis is to analyze the most common security vulnerabilities of household IoT devices, identify risks associated with remote communication, and verify selected security threats through practical testing. The theoretical part is based on academic literature, technical documentation, and public vulnerability databases including CVE, NVD, and CWE. The thesis also includes an analysis of vulnerability trends and methods for evaluating their severity using the CVSS framework. The practical part is conducted as a case study of four IP cameras intended for home use. During the testing process, the network communication of the devices was analyzed and selected attacks were simulated in an isolated laboratory environment. The results show that even commonly available IP cameras may contain serious security weaknesses, particularly in the areas of remote access, credential protection, and communication security. At the same time, the analysis confirmed that network traffic metadata may represent a significant privacy risk even when the communication itself is encrypted. Based on the findings, the thesis proposes recommendations aimed at improving the security of IoT devices in smart home environments.
