An Effective Security Method Based on Combining 802.1x, DMZ and SSL-VPN for IoT Network Security

İlhan Fırat KılınçerFatih ErtamOrhan YamanAbdülkadir Şengür

IoT applications appear in many areas due to their flexible structures and many advantages they provide. The increase in IoT applications brings many security vulnerabilities. In order to close these security gaps and ensure the security of the created system, some measures should be taken by combining existing technologies with new technologies. In this study, a method that uses various security technologies together is proposed to ensure the security of the IoT application network. Accordingly, 802.1x technology was used to connect wireless sensor devices to a Wi-Fi network. Thus, in the first step, unauthorized users are not allowed to connect to this network. In the second step, IoT data was collected on a central server, and this server was taken to the DMZ zone in the firewall. Thus, access to the server is both restricted, and server access is logged. In the last step, with SSL-VPN configured in the firewall, data can be safely monitored from the external environment. The biggest advantages of the proposed approach are that it can be used easily in existing Wi-Fi networks, provides communication security, and is low cost. Considering these advantages, it is considered to be an important work in the field of IoT network security.

IoT Ağ Güvenliği için 802.1x, DMZ ve SSL-VPN Birleştirme Tabanlı Etkili bir Güvenlik Yöntemi

İlhan Fırat KılınçerFatih ErtamOrhan YamanAbdülkadir Şengür

IoT uygulamaları, sahip oldukları esnek yapıları ve sağladıkları birçok avantajdan dolayı birçok alanda karşımıza çıkmaktadırlar. IoT uygulamalarındaki artış, birçok güvenlik açığını da getirmektedir. Bu güvenlik açıklarını kapatmak ve oluşturulan sistemin güvenliğini sağlamak için mevcut teknolojiler, yeni teknolojilerle birleştirilerek bazı önlemler alınmalıdır. Bu çalışmada, IoT uygulama ağının güvenliğini sağlamak için, çeşitli güvenlik teknolojilerini bir arada kullanan bir yöntem önerilmiştir. Buna göre, kablosuz sensör cihazlarının, Wi-Fi ağına bağlanması için 802.1x teknolojisini kullanıldı. Böylelikle, ilk adımda yetkisiz kullanıcıların bu ağa bağlanmasına izin verilmez. İkinci adımda IoT verileri merkezi bir sunucu üzerinde toplanmış ve bu sunucu güvenlik duvarındaki DMZ bölgesine alınmıştır. Böylece, sunucuya erişim hem kısıtlanır hem de sunucu erişimlerinin günlüğü tutulur. Son adımda, güvenlik duvarında konfigüre edilen SSL-VPN ile dış ortamdan verilerin güvenli bir şekilde izlenmesi sağlanmıştır. Önerilen yaklaşımın en büyük avantajları, mevcut Wi-Fi ağlarında rahatlıkla kullanılabilir olması, haberleşme güvenliğini sağlaması ve düşük maliyetli olmasıdır. Bu avantajları göz önünde bulundurulduğunda, IoT ağ güvenliği alanında önemli bir çalışma olduğu düşünülmektedir.
