“…Which provide virtualized switches, virtualized routers and virtualized firewalls and even virtualized entire network such as ISP. NVF provides easiest flexible and scalable network functions deployment [21]. The market size of NVS is expected to grow to USD 39.3 billion$ by 2023, it was about 12.9 billion$ in 2019, at a Compound Annual Growth Rate (CAGR) of 22.90% during the estimate period [13].…”

Infrastructure as a Service (IaaS) provides logical separation between data, network, applications and machines from the physical constrains of real machines. IaaS is one of the basis of cloud virtualization. Recently, security issues are also gradually emerging with virtualization of cloud computing. Different security aspects of cloud virtualization will be explored in this research paper, security recognizing potential threats or attacks that exploit these vulnerabilities, and what security measures are used to alleviate such threats. In addition, a discussion of general security requirements and the existing security schemes is also provided. As shown in this paper, different components of virtualization environment are targets to various attacks that in turn leads to security issues compromising the whole cloud infrastructure. In this paper an overview of various cloud security aspects is also provided. Different attack scenarios of virtualization environments and security solutions to cater these attacks have been discussed in the paper. We then proceed to discuss API security concerns, data security, hijacking of user account and other security concerns. The aforementioned discussions can be used in the future to propose assessment criteria, which could be useful in analyzing the efficiency of security solutions of virtualization environment in the face of various virtual environment attacks.

“…• Virtual Network Function (VNF): VNFs is a software implementation of the network functions of NDs, which run in one or more containers or in virtual machines [160]. To manage the functionality of VNFs, Element Management System (EMS) is deployed to ensure the synchronization between them [161].…”

Softwarization of UAV Networks: A Survey of Applications and Future Trends

Unmanned Aerial Vehicles (UAVs) have become increasingly important in assisting 5G and beyond 5G (B5G) mobile networks. Indeed, UAVs have all the potentials to both satisfy the ever-increasing mobile data demands of such mobile networks and provide ubiquitous connectivity to different kinds of wireless devices. However, the UAV assistance paradigm faces a set of crucial issues and challenges. For example, the network management of current UAV-assisted systems is time consuming, complicated, and carried out manually, thus causing a multitude of interoperability issues. To efficiently address all these issues, Software-Defined Network (SDN) and Network Function Virtualization (NFV) are two promising technologies to efficiently manage and improve the UAV assistance for the next generation of mobile networks. In the literature, no clear guidelines are describing the different use cases of SDN and NFV in the context of UAV assistance to terrestrial networks, including mobile networks. Motivated by this fact, in this survey, we guide the reader through a comprehensive discussion of the main characteristics of SDN and NFV technologies. Moreover, we provide a thorough analysis of the different classifications, use cases, and challenges related to UAV-assisted systems. We then discuss SDN/NFV-enabled UAV-assisted systems, along with several case studies and issues, such as the involvement of UAVs in cellular communications, monitoring, and routing, to name a few. We furthermore present a set of open research challenges, high-level insights, and future research directions related to UAV-assisted systems.

“…NFV allows Internet Service Providers to provide flexible network service deployments. However, recent research [12] have shown that this new technology should be secured from both the service provider and the end-user perspective. NVF surveys [13], [14], [15] have pointed out multiple threats and vulnerabilities in NFV, where end-user privacy is an open issue.…”

Dynamic setup of IPsec VPNs in service function chaining

This article describes a novel mechanism for the automated establishment of dynamic Virtual Private Networks (VPN) in the application domain of Network Function Virtualization (NFV). Each hop in an NFV Service Function Chain (SFC) lacks the capability of perflow encryption, that makes the traffic flow in federated NFV environments vulnerable for eavesdropping. Due to the possible lack of bidirectional data plane communication channels between VNFs in an SFC, the Internet Security Key Exchange protocol (IPsec-IKE) is not applicable inside a VNF. Hence, this article introduces an alternative to IPsec-IKE that is specifically designed for NFV environments. This component is named Software Defined Security Associations (SD-SA), which is shown through a proof of concept evaluation to perform better than IPsec-IKE with respect to bandwidth and resource consumption.
