Experience has shown that virtualization can provide a dramatic increase in the efficiency and effectiveness of complex organizations and communities, and is expected to constitute an important technological pillar of a thriving data-driven economy and the European single digital market. However, virtualization also bears a number of (new) security risks. First, some risks are shared with traditional computing environments and include, for instance, issues affecting operating systems, communication protocols, and applications. Second, the above issues may even be exacerbated by the use of virtualized components, producing a greater security impact. For instance, privilege escalation may have increased impact if the target of the escalation is the OS of the physical machine hosting a virtualized system. Finally, virtualization also introduces a number of virtualization-specific security issues that require ad hoc solutions. For instance, new security issues are related to multi-tenancy allowing cross-platform information flow between customers sharing the same physical host, and allowing adversaries to execute arbitrary out-of-the-guest code without owning the required access rights. Nowadays, as the basis of distributed infrastructures like the cloud, virtualized environments are adopted pervasively and therefore increasingly targeted by cyber-attacks. Even more elaborated and specialized attacks are currently being devised to exploit vulnerabilities or weaknesses at the virtualization layer. This report provides an analysis of the status of virtualization security. In it, we present current efforts, emerging best practices and known security gaps, discussing the impact the latter have on environments based on virtualization technologies.

Virtualization has become a widely and attractive employed technology in cloud computing environments. Sharing of a single physical machine between multiple isolated virtual machines leading to a more optimized hardware usage, as well as make the migration and management of a virtual system more efficiently than its physical counterpart. Virtualization is a fundamental technology in a cloud environment. However, the presence of an additional abstraction layer among software and hardware causes new security issues. Security issues related to virtualization technology have become a significant concern for organizations due to arising some new security challenges. This paper aims to identify the main challenges and risks of virtualization in cloud computing environments. Furthermore, it focuses on some common virtual-related threats and attacks affect the security of cloud computing. The survey was conducted to obtain the views of the cloud stakeholders on virtualization vulnerabilities, threats, and approaches that can be used to overcome them. Finally, we propose recommendations for improving security, and mitigating risks encounter virtualization that necessary to adopt secure cloud computing.

This paper reviews, discusses, and highlights some of the standard cloud computing vulnerabilities primarily related to virtualization platforms and their implementations while outsourcing services and resources to different end-users and business enterprises. Furthermore, we provide Blockchain-enabled solutions for virtualized cloud computing platform involving both the end-users as well as cloud service providers (CSP) to address and solve different security and privacy-related vulnerabilities using blockchain-enabled solutions to improve their cloud services and resource provisioning facilities.

Cyber threats against clouds have evolved rapidly. Traditional reactive cyber defense technologies are not effective and sufficient to protect federated clouds. This chapter introduces the novel federated cloud security architecture that includes proactive cloud defense technologies for secure and agile cloud development. The federated security architecture consists of a set of seamlessly integrated systematic security mechanisms at the application layer, the network layer and the system layer in federated cloud computing environments. Features of the architecture include: (1) it is centered on proactive cyber defense; (2) it facilitates to detect early warning cyber attacks against at one layer and deploy early warning signs of attacks to other layers for countermeasures; (3) it uses command and control (C2) to coordinate both in-cloud and cross-cloud defense activities via federated cloud security centers. 1

Cloud computing represents the most recent enterprise trend in information technology and refers to the virtualization of computing resources that are available on demand. Cloud computing saves cost and time for businesses. Moreover, this computing process reflects a radical technological revolution in how companies develop, deploy, and manage enterprise applications over the Internet. Virtualized cloud computing mainly offers cloud-computing delivery models such as software as a service, platform as a service, and infrastructure as a service. Security and privacy are presently considered critical factors in the adaptation of any cloud-service delivery model. Cloud computing leverages several technologies; in the process , this model can inherit potential security threats. Thus far, security issues in cloud computing have rarely been addressed at the service delivery level. Key security concerns include Web application security, network security, data security, integration, vulnerabilities in the virtualized environment, and physical security. The aim of this research is to comprehensively present the security threats with respect to their cloud service deliver models. This study also determines how service delivery models differ from existing enterprise applications, classify these models, and investigate the inherent security challenges. This study primarily focuses on the security concerns of each layer of the cloud-service delivery model, as well as on existing solutions and approaches. In addition, countermeasures to potential security threats are also presented for each cloud model.
