Kritik Altyapılarda Siber Risk Analizi ve Yönetimi
İşlevini kısmen veya tamamen yerine getiremediğinde çevrenin, toplumsal düzenin ve kamu hizmetlerinin yürütülmesinin olumsuz etkilenmesi neticesinde, vatandaşların sağlık, güvenlik ve ekonomisi üzerinde ciddi etkiler oluşturacak ağ, varlık, sistem ve yapıların bütünü kritik altyapı olarak değerlendirmektedir. Bahse konu yapıların hayati önemi nedeniyle korunması ve korunabilmesi için de öncelikle değerinin bilinmesi ve hangi risklere maruz olduğunun tespiti gereklidir. Bu kapsamda yapılacak çalışmalar risk analizi olarak değerlendirilmekte olup, risk analizi kritik altyapının bozulmasının ya da yıkımının olası etkileri ile zayıf noktalarını değerlendirebilmek için ilgili tehdit senaryolarının göz önünde bulundurulmasıdır. Konunun öneminin gün geçtikçe artması nedeniyle hem ülkeler hem de uluslararası kuruluşlar tarafından standartların belirlenmesi, koruma çerçeveleri oluşturulması çalışmaları hız kazanmıştır. Bu çalışmada uluslararası standart ve çerçevelerden faydalanarak kritik altyapıların korunması, risk analizi ve yönetiminin yapılmasına yönelik bir çatı önerilmiştir.

Cyber Risk Analysis and Management for Critical Infrastructures
As a result of the negative impact of the environment, the social order and the public services when it fails to fulfill its function partially or completely, it considers the network, assets, systems and structures that will have a serious impact on the health, safety and economy of the citizens as a critical infrastructure. In order to protect these buildings due to their vital importance, it is necessary to know the value and to determine which risks they are exposed to. The studies to be carried out in this scope are considered as risk analysis that is to take into account the related threat scenarios in order to evaluate the possible effects and weaknesses of the degradation or destruction of the critical infrastructure. As the importance of the issue has increased day by day, efforts have been accelerated by both countries and international organizations to set standards and to establish protection frameworks. In this work, a framework is proposed to form for the protection of critical infrastructures, risk analysis and management by making use of international standards and frameworks.
