20.500.12556/RUL-172600 Izdelava kibernetske vabe na osnovi digitalnega dvojčka pametnega termostata Implementation of a honeypot based on a digital twin of a smart thermostat Diplomsko delo obravnava problematiko kibernetske varnosti na področju interneta stvari (ang. Internet of Things). Osrednji cilj je bil razvoj in preizkus specializirane kibernetske vabe z visoko stopnjo interakcije, ki temelji na konceptu digitalnega dvojčka pametnega termostata. Razvito orodje realistično simulira delovanje prave naprave z uporabo termodinamičnih modelov in dinamičnega odzivanja na okoljske spremembe. Implementirana simulacija vključuje sezonske in dnevne temperaturne cikle, naravno toplotno izmenjavo ter sistem HVAC s histerezo. Pametni termostat ima več API končnih točk, s katerimi se lahko bere in nastavlja več parametrov delovanja. Skozi delo so predstavljeni ključni koncepti, od zgodovine in delovanja različnih vrst honeypotov do njihove strateške postavitve v omrežju. Podrobno je opisan proces razvoja, vključno z izbiro tehnologij, kot sta Python z ogrodjem Flask in Docker, ter reševanjem tehničnih izzivov pri ustvarjanju prepričljive simulacije. Sistem je bil postavljen na strežnik z javnim IP-naslovom in testiran tri tedne, v katerih je privabil 14578 napadov iz 808 unikatnih IP-naslovov. Analiza je pokazala, da večina napadov izvira iz podatkovnih centrov, pri čemer je bilo 58,61 %} napadalcev identificiranih kot avtomatski skenerji. Sistem za zaznavanje zlonamernih vzorcev je uspešno prestregel različne napadalske tehnike, vključno z vbrizgavanjem ukazov in poskuse okužbe z zlonamerno programsko opremo. The thesis addresses the issue of cybersecurity in the Internet of Things (IoT). The main objective was to develop and test a specialized high-interaction honeypot based on the concept of a smart thermostat's digital twin. The developed tool realistically simulates the operation of a real device using thermodynamic models and dynamic responses to environmental changes. The implemented simulation includes seasonal and daily temperature cycles, natural heat exchange, and an HVAC system with hysteresis. The smart thermostat features multiple API endpoints for reading and configuring various operational parameters. The thesis also covers key concepts, including the history, operation of different types of honeypots and strategic placement within a network. It provides a detailed description of the development process, including the choice of technologies such as Python, the Flask framework, and Docker, as well as the technical challenges overcome in creating a convincing simulation. The system was deployed on a server with a public IP address and tested for three weeks, during which it was subjected to 14,578 attacks from 808 unique IP addresses. The analysis revealed that the majority of attacks originated from data centers, with 58.61%} of the attackers identified as automated scanners. The malicious pattern detection system successfully intercepted various attack techniques, such as command injection and malware infection attempts. kibernetska varnost pametni termostat honeypot digitalni dvojček IoT Docker Elastic sklad cybersecurity smart thermostat honeypot digital twin IoT Docker Elastic stack true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-09 13:25:25 2025-09-09 13:25:30 2025-10-16 03:56:48 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 62554 251695619 Laszló_Mateo_-_Izdelava_kibernetske_vabe_na_osnovi_digitalnega_dvojcka_pametnega_termostata.pdf Laszló_Mateo_-_Izdelava_kibernetske_vabe_na_osnovi_digitalnega_dvojcka_pametnega_termostata.pdf 1 B6BD72894CA9BCD67B5F573D4D9928DC ab61c1b3f01e9af6acf61d5b899f5666f05e5df98bf0f0435eeec47882c09673 89413a60-8d6f-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=216510 Fakulteta za elektrotehniko 0 0 0
