“…Data remanence may be discovered by computer forensics and other various techniques. In addition, it is possible to find and recover files that might have been removed from a computer [103]. Cloud providers have not fully addressed data remanence, and this issue is even ignored by some cloud providers, even though it is one of the most critical issues.…”

Cloud computing is currently becoming a well-known buzzword in which business titans, such as Microsoft, Amazon, and Google, among others, are at the forefront in developing and providing sophisticated cloud computing systems to their users in a cost-effective manner. Security is the biggest concern for cloud computing and is a major obstacle to users adopting cloud computing systems. Maintaining the security of cloud computing is important, especially for the infrastructure. Several research works have been conducted in the cloud infrastructure security area; however, some gaps have not been completely addressed, while new challenges continue to arise. This paper presents a comprehensive survey of the security issues at different cloud infrastructure levels (e.g., application, network, host, and data). It investigates the most prominent issues that may affect the cloud computing business model with regard to infrastructure. It further discusses the current solutions proposed in the literature to mitigate the different security issues at each level. To assist in solving the issues, the challenges that are still unsolved are summarized. Based on the exploration of the current challenges, some cloud features such as flexibility, elasticity and the multi-tenancy are found to pose new challenges at each infrastructure level. More specifically, the multi-tenancy is found to have the most impact at all infrastructure levels, as it can lead to several security problems such as unavailability, abuse, data loss and privacy breach. This survey concludes by giving some recommendations for future research.

“…When one of these operations is carried out, there is a risk that the data are still resident in memory, and thus can be retrieved even after it appears that the data has been deleted or moved from the system. This can lead to the data falling in the hands of a malicious user [23]. In addition, data are typically stored in backup servers, so when data are deleted from the primary cloud server, CPSs must intentionally execute a delete operation on the data stored in the backup server so as to delete copies of the data [5].…”

Existing classification systems of cloud computing security challenges have mostly excluded human error as a major root cause of cloud security issues. Therefore, we propose a new cloud security challenge classification system by adding Human Error as a category and retaining the most relevant categories-Network, Data Access, and Virtualization-from previous research. Through a literature survey, we identified effective defensive measures that are used by experts to combat these security challenges and we provided a mapping of the challenges to their defensive measures. Our findings reveal that there is, indeed, a case for human error to be included as a category in the classification of the security challenges encountered in cloud computing, and if cloud service providers (CSPs) and their customers are fully informed on the security challenges encountered in the cloud, both parties can fully benefit from the advantages this model of computing offers.

Usage of Multi-user Environment services leaves traces of the client data on different servers (passwords, keys etc.). Since, most of the cloud servers use virtualization technology, it is difficult to find the co-resident virtual machine attacks in the private and public cloud systems. This was the great risk for the client accessing the multi-user environment services, with the leakage of their confidential information. So several memory reconstruction mechanisms are their by examine those mechanisms and develop a mechanism to only authorized person can access the confidential data. This paper introduces an overview of cloud data replication issues, data security issues and cloud attacks in the multi-user cloud computing environment. Hence, It is necessary to decrease the server maintenance cost by migrating the cloud user's sensitive data in a secured framework for future reference.
