“…Typical confidentiality threats that can affect virtual networks are sniffing and spoofing attacks [143]. Moreover, if from a user's prospective the virtual network is a private network, it might in reality rely on a public infrastructure and therefore appropriate protections to secure communications are needed [110]. A novel type of attack that exploits virtual networks as a cornerstone for subsequently compromising the whole Cloud system is the "virtual switch attacker model for packet-parsing" (vAMP attack) [131].…”

The Internet of Things (IoT) is rapidly changing our society to a world where every "thing" is connected to the Internet, making computing pervasive like never before. This tsunami of connectivity and data collection relies more and more on the Cloud, where data analytics and intelligence actually reside. Cloud computing has indeed revolutionized the way computational resources and services can be used and accessed, implementing the concept of utility computing whose advantages are undeniable for every business. However, despite the benefits in terms of flexibility, economic savings, and support of new services, its widespread adoption is hindered by the security issues arising with its usage. From a security perspective, the technological revolution introduced by IoT and Cloud computing can represent a disaster, as each object might become inherently remotely hackable and, as a consequence, controllable by malicious actors. While the literature mostly focuses on security of IoT and Cloud computing as separate entities, in this article we provide an up-to-date and well-structured survey of the security issues of Cloud computing in the IoT era. We give a clear picture of where security issues occur and what their potential impact is. As a result, we claim that it is not enough to secure IoT devices, as cyber-storms come from Clouds.

“…However, their main goal is to give a high level description of potential problems, not on providing a fine-grained analysis of how each of the many threats identified apply to specific scenarios (e.g., virtual networking). On the other hand, there are works in the literature that investigate SVNs in more depth, such as (Chowdhury and Boutaba, 2010; Schoo et al, 2011;Natarajan and Wolf, 2012). Unfortunately, since their goal is to survey solutions and to identify challenges in the area, they fail to provide a reusable classification of the virtual networking threats described.…”

A central component of managing risks in cloud computing is to understand the nature of security threats. The relevance of security concerns are evidenced by the efforts from both the academic community and technological organizations such as NIST, ENISA and CSA, to investigate security threats and vulnerabilities related to cloud systems. Provisioning secure virtual networks (SVNs) in a multi-tenant environment is a fundamental aspect to ensure trust in public cloud systems and to encourage their adoption. However, comparing existing SVN-oriented solutions is a difficult task due to the lack of studies summarizing the main concerns of network virtualization and providing a comprehensive list of threats those solutions should cover. To address this issue, this paper presents a threat classification for cloud networking, describing threat categories and attack scenarios that should be taken into account when designing, comparing, or categorizing solutions. The classification is based on the CSA threat report, building upon studies and surveys from the specialized literature to extend the CSA list of threats and to allow a more detailed analysis of cloud network virtualization issues. 214 M.

Cloud computing is the latest emerging technology which offers reduced capital expenditure, complexity, operational risks, maintenance, and increased scalability while providing the services at different abstraction levels, namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). A new approach called cloud networking that enables and adds the networking functions and resources to cloud computing and provide the means of dynamic and flexible placement of virtual resources that crossing over provider borders. It also allows various kinds of functionalities and optimization techniques, e.g., reducing network load. This approach brings out and enables new security challenges. This paper presents a new security architecture, which enables the user of cloud networking to illustrate the security requirements and apply them in the cloud networking infrastructure.
