  Abstract: Emergence of cloud computing technologies have changed the way we store, retrieve, and archive our data. With the promise of unlimited, reliable and always-available storage, a lot of private and confidential data are now stored on different cloud platforms. Being such a gold mine of data, cloud platforms are among the most valuable targets for attackers. Therefore, many forensics investigators have tried to develop tools, tactics and procedures to collect, preserve, analyse and report evidences of attackers’ activities on different cloud platforms. Despite the number of published articles there isn’t a bibliometric study that presents cloud forensics research trends. This paper aims to address this problem by providing a comprehensive assessment of cloud forensics research trends between 2009 and 2016. Moreover, we provide a classification of cloud forensics process to detect the most profound research areas and highlight remaining challenges.
