Cloud Computing has many facets to it which makes it diverse. Investigation of a cyber-crime that involves the cloud as a subject, object, or as an environment, is cloud forensics. Challenges in cloud forensics exist at every phase of digital forensics. To provide a holistic solution to overcome these challenges we must first understand the cloud forensics landscape (the Cloud). The elements which give the Cloud the diversity that it has, and have an impact on the forensics process of the cloud should be taken into consideration while designing the cloud forensics framework. In this paper, the researchers present a comprehensive survey of the research trend in cloud forensics. The paper also proposes a cloud forensics taxonomy based on the paradigms of cloud computing that have an impact on cloud forensics. Although forensics solution taxonomies have been proposed earlier, this paper aims at a taxonomy solution at a more generic level. The proposed taxonomy provides cloud forensics solution strategies for efficient cloud forensics.

云计算具有许多方面，这使其变得多样化。对涉及云作为主题，客体或环境的网络犯罪进行调查是云取证。数字取证的每个阶段都存在云取证的挑战。为了提供整体解决方案来克服这些挑战，我们必须首先了解云取证领域（Cloud）。在设计云取证框架时，应考虑使云具有多样性并影响云取证过程的要素。在本文中，研究人员对云取证研究的趋势进行了全面的调查。本文还提出了一种基于云计算范式的云法证学分类法，该范式会对云法证学产生影响。尽管较早提出了取证解决方案分类法，但本文还是针对更通用的分类学解决方案。拟议的分类法为有效的云取证提供了云取证解决方案策略。
