Forensics Investigation in The Cloud: Determining Where Evidence Starts And Ends

Abstract

This article examines the effects of cloud computing technologies on digital forensics processes within the framework of their benefits and challenges (such as lack of physical access, data volatility, and legal complexities). While analyzing how incident response and digital evidence collection differ in the cloud, this study introduces the original Cloud Evidence Lifecycle Model (CELM) and the Evidence Accessibility and Integrity Scale (KEBS) as a methodological solution to the question of 'where evidence begins and ends in the cloud.' Forensic investigation steps and encountered issues are evaluated in light of these models through the LastPass data breach case. The study emphasizes the need for reassessing cloud systems from a digital forensics perspective, the contribution of the proposed models to this process, and the importance of enhancing organizational preparedness.

Bulut Ortamında Adli İnceleme: Kanıtın Nerede Başlayıp Nerede Bittiğinin Belirlenmesi

Abstract

Bu makale, bulut bilişim teknolojilerinin adli bilişim süreçlerine etkilerini, sunduğu faydalar ve getirdiği zorluklar (fiziksel erişim eksikliği, veri uçuculuğu, yasal karmaşa) çerçevesinde incelemektedir. Olay müdahalesi ve dijital delil toplamanın bulutta nasıl farklılaştığı analiz edilirken, 'bulutta kanıt nerede başlar, nerede biter?' sorusuna metodolojik bir çözüm olarak özgün Bulutta Kanıt Yaşam Döngüsü Modeli (CELM) ve Kanıtın Erişilebilirlik ve Bütünlük Skalası (KEBS) sunulmaktadır. LastPass veri ihlali vakası üzerinden bu modeller ışığında adli inceleme adımları ve karşılaşılan sorunlar değerlendirilmiştir. Çalışma, bulut sistemlerinin adli bilişim açısından yeniden değerlendirilmesi, önerilen modellerin bu sürece katkısı ve kurumsal hazırlığın artırılması gerektiğini vurgulamaktadır.
