Abstract

Perkembangan Internet of Things (IoT) telah mendorong adopsi teknologi Smart Home, termasuk perangkat smart door lock yang memungkinkan kontrol akses pintu secara jarak jauh melalui jaringan lokal maupun internet. Meskipun memberikan kenyamanan, sistem ini berisiko menjadi target serangan siber apabila komunikasi data tidak diamankan dengan baik. Penelitian ini bertujuan untuk menganalisis kerentanan jaringan pada sistem smart door lock menggunakan metode penetration testing dengan skenario Man-in-the-Middle (MITM). Pengujian dilakukan terhadap tiga jenis komunikasi: tanpa enkripsi (HTTP), dengan enkripsi (HTTPS), dan koneksi melalui server cloud. Tools seperti Wireshark, Bettercap, dan mitmproxy digunakan untuk mengevaluasi apakah data dapat disadap, dimodifikasi, atau diputar ulang. Hasil menunjukkan bahwa sistem smart door lock masih rentan terhadap serangan MITM, terutama saat komunikasi tidak menggunakan protokol keamanan seperti TLS. Replay attack berhasil dilakukan pada skenario HTTP dengan tingkat keberhasilan 100% karena berdampak pada confidentiality, integrity, dan availability. Pada skenario HTTPS, payload terenkripsi sehingga serangan hanya berhasil 0%. Penelitian ini merekomendasikan penerapan enkripsi yang kuat, token dinamis, dan autentikasi berlapis untuk meningkatkan keamanan perangkat IoT sejenis. The rapid development of the Internet of Things (IoT) has accelerated the adoption of Smart Home technologies, including smart door lock devices that enable remote door access control via local networks or the internet. While offering convenience, these systems are at risk of becoming targets of cyberattacks if data communication is not properly secured. This study aims to analyze network vulnerabilities in smart door lock systems using penetration testing with Man-in-the-Middle (MITM) scenarios. The experiments were conducted on three types of communication: unencrypted (HTTP), encrypted (HTTPS), and cloud-based connections. Tools such as Wireshark, Bettercap, and mitmproxy were employed to evaluate whether data could be intercepted, modified, or replayed. The results indicate that smart door lock systems remain vulnerable to MITM attacks, particularly when communication does not use security protocols such as TLS. Replay attacks were successfully executed in the HTTP scenario with a 100% success rate, impacting confidentiality, integrity, and availability. In the HTTPS scenario, the payload was encrypted, making the attack success rate 0%. This study recommends the implementation of strong encryption, dynamic tokens, and multi-layer authentication to enhance the security of IoT devices.
