# Cyberattacks and Security of Cloud Computing: A Complete Guideline
## 2 Threat Reasons in Cloud Computing
### Recent Studies in Cloud Security  
[PERSON] and [PERSON] [15] conducted a survey focused on the contemporary security challenges within MultiCloud Computing (MCC). They address the transition from local to cloud computing, which has brought about security challenges for both clients and service providers. The primary objective of their paper is to provide insights into the core characteristics of Cloud Computing (CC) and MultiCloud Computing (MCC). Additionally, they delve into the security issues associated with these models and propose potential solutions. The researchers specifically address the types of security risks, the security mechanisms employed, and the various cloud deployment models relevant to each risk. [PERSON] et al. [16] conducted a comprehensive review of cloud computing security challenges. Their study sheds light on critical concerns in securing cloud computing environments, including trust, authenticity, confidentiality, encryption, key management, multitenancy, data splitting, and virtual machine security. They also proposed potential solutions to mitigate these challenges. Notably, the study emphasized the importance of addressing resource-sharing issues in cloud environments, suggesting this as a priority for future research in the field of cloud security. [PERSON] et al. [17] conducted a survey examining security concerns within various service delivery models of cloud computing. They explore issues related to data privacy, data integrity, authentication, authorization, and access control. The authors also examine the risks associated with multitenancy, virtualization, and the potential for unauthorized data exposure. Additionally, the paper addresses security concerns arising from the geographical distribution of cloud data centers. They also noted the advantages of cloud computing, including swift deployment, pay-as-you-go pricing, cost reduction, flexibility, rapid provisioning, enhanced scalability, improved stability, and hypervisor protection against network-based attacks. [PERSON] et al. [18] discussed various artificial intelligence methods and technologies aimed at enhancing the protection of cloud computing systems. In particular, their research examined the significant security threats within cloud computing environments, which often involve the abusive and malicious utilization of cloud services. The paper highlighted the use of Intrusion Detection Systems (IDPs) as a valuable tool in identifying security policy issues, recording existing threats, and preventing data exchange participants from violating security policies. In their paper, [PERSON] et al. [19] conduct an extensive survey focusing on the security and privacy challenges within the realm of cloud computing. They also explore potential solutions and outline future research directions in this field. The authors underscore that the adoption of cloud computing has introduced a host of security challenges. These challenges pertain to safeguarding data, applications, and services hosted within cloud environments. Security risks may involve unauthorized access, data breaches, loss of control over data, and compliance with regulatory requirements. [PERSON] et al. [20] conducted a review focused on cloud storage security risks, practices, and measures. The primary objective of their paper was to examine security concerns and present contemporary implementations aimed at addressing them. The authors identify several security risks associated with cloud storage, including challenges related to data visibility, unprotected storage locations, data breaches, and vulnerabilities in application programming interfaces (APIs). These risks have the potential to lead to significant financial losses and data exposure for individuals and organizations. It offers practical guidance on mitigating risks and implementing effective security measures, making it a valuable resource for organizations and individuals looking to enhance their cloud storage security practices.
