In recent years, cloud computing has gained popularity, and it is now used to support various areas of human life. Cloud forensics has been introduced to help forensic investigators find potential evidence against cloud criminal activities and maintain the security and integrity of the information stored in the cloud. While great research in the area has been carried out concerning challenges and solutions, the research on methodologies and frameworks is still in its infancy. This article focuses on the methodological aspects of cloud forensics. It critically reviews cloud forensics' existing challenges and solutions, and it explores, based on a detailed review of the area, all the work that has been carried out both in digital and cloud forensic methodologies mainly for supporting the investigation of security incidents in cloud. Furthermore, the detailed comparison reveals similarities and drawbacks of the existing methodologies providing some novel future research directions. Finally, the specific paper can be considered as a starting point for researchers wishing to design cloud-forensicable services over the cloud.
