Özellikle akıllı şebekelerde kritik altyapıların kontrolünde kullanılan Endüstriyel Kontrol Sistemleri, üretkenlik, ekonomi ve hız gibi insan hayatını kolaylaştıran faktörler nedeniyle izole bir ağ mimarisinden kablolu ve kablosuz dış ağlara hızlı bir geçiş yapmıştır. Bu geçişle birlikte endüstriyel kontrol sistemlerine özgü protokoller yetersiz kalmış ve hibrit protokoller kullanılmaya başlanmıştır. Sonuç olarak, endüstriyel kontrol sistemlerine özgü zafiyetlerin yanı sıra internete ve yeni protokoller özgü zafiyetler, kontrol sistemlerini tehdit etmeye başlamıştır. Bu çalışmada, sahte veri enjeksiyonu saldırısının gerçekleştirildiği akıllı şehirler ve ağ altyapıları için çözüm önerisi olarak ışık bağlantısı (Li-Fi) iletim altyapısının veri iletiminde kullanılabilirliği araştırılmıştır. Bu çalışmanın, endüstriyel kontrol sistemleri güvenliği kapsamında diğer çalışmalara önemli katkılar sağlayacağı düşünülmektedir.

A New Approach in Cyber Security of Industrial Control Systems: Li-Fi

Öz

Industrial Control Systems used in the control of critical infrastructures, especially in smart grids, have made a rapid transition from an isolated network architecture to wired and wireless external networks due to the factors that facilitate human life such as productivity, economy and speed. With this transition, industrial control systems specific protocols have become insufficient and hybrid protocols have started to be used. As a result, the vulnerabilities specific to the internet and new protocols besides the vulnerabilities specific to industrial control systems have started to threaten control systems. In this study, the usability of the Light Fidelity (Li-Fi) transmission infrastructure in data transmission was investigated as a solution proposal for the smart city / network infrastructure where attack of False Data Injection carried out. This study will make important contributions to the studies carried out for industrial control systems security.
