Using cloud computing, businesses can adopt IT without incurring a significant upfront cost. The Internet has numerous benefits, but model security remains a concern, which affects cloud embracing negatively. The security challenge gets too difficult underneath data center, while additional dimensions such as model design, multitenancy, elasticity, and the layers dependency stack have been added to the problem scope. We present a thorough examination of the cloud security challenge in this article. We looked at the issue from the standpoints of network infrastructure: cloud-provided features, cloud consumers, and cloud service delivery methods. Based on this research, we developed an in-depth characterization of the data protection challenge and recommended security solutions that should address the critical aspects of the issue. Cloud computing is an exploding field of research that relies on distributing computing power instead of using dedicated computers or smart devices. Most of the growth in this sector is attributed to the indispensability of electronic and digital gadgets and the shift from a traditional IT subscription model to a unique cloud model. Cloud computing offered a significant danger and difficulty for information system projects, but it also provided them with several possibilities to improve their data processing. It has also been noted that cloud users and consumers do not yet have the necessary forensic skills to detect illegal activity in the cloud. Although the cloud offers potential technological and economic advantages, consumers have been reluctant to adopt it primarily due to security concerns and the difficulty of conducting an appropriate investigation into the cloud. Some study has been done in this area, and strategies for conducting forensic investigations have been proposed. In this research paper, we begin by analyzing the intrusion detection progress made by other academics, and then we analyze and evaluate our conclusions in order to assess the potential difficulties that cloud forensics face based on these findings.

“…5) Open, Multi-Tenancy: It should allow new tenants to enter the system, connect services/agents by different vendors, and create new value out of them. The benefits of such a multi-tenancy include efficiency through shared resources and competitive costs [25]. 6) Distribution: It should allow the seamless distribution of computing tasks, on the one hand connecting different types of devices (e.g.…”

“…Virtualization abstracts and multiplexes the shared physical infrastructure of a cloud service provider (CSP) and hides the complexity of its underlying pool of virtualized resources. Multitenancy, on the other hand, allows different tenants to share the pool of virtualized resources provided by the CSP (Auer et al., 2019; Goyal et al., 2019). Both these techniques are realized by the concept of a VM instance.…”

“…It would only take another tenant, who might be a competitor, to launch an inter‐VM attack targeted at its rival to gain access to their confidential data. For this reason, the ever‐increasing demand of cloud computing services places VM placement at the heart of CSPs’ decision‐making process (Goyal et al., 2019).…”

For businesses to benefit from the many opportunities of cloud computing, they must first address a number of security challenges, such as the potential leakage of confidential data to unintended third parties. An inter‐VM (where VM is virtual machine) attack, also known as cross‐VM attack, is one threat through which cloud‐hosted confidential data could be leaked to unintended third parties. An inter‐VM attack exploits vulnerabilities between co‐resident guest VMs that share the same cloud infrastructure. In an attempt to stop such an attack, this paper uses the principles of logical analysis to model a solution that provides physical separation of VMs belonging to conflicting tenants based on their levels of conflict. The derived mathematical model is founded on scientific principles and implemented using four conflict‐aware VM placement algorithms. The resultant algorithms consider a tenant's risk appetite and cost implications. The model offers guidance to VM placement and is validated using a proof of concept. A cloud simulation tool was used to test and evaluate the effectiveness and efficiency of the model. The findings reflect that the introduction of the proposed model introduced a time lag in the time it took to place VM instances. On top of this, it was also discovered that the number and size of the VM instances has an effect on the VM placement performance. The findings further illustrate that the conflict tolerance level of a VM has a direct impact on the time it took to place.
