5G represents the next major phase of mobile telecommunication systems and network architectures beyond the current 4G standards, aiming at extreme broadband and ultra-robust, low latency connectivity, to enable the programmable connectivity for the Internet of Everything. Despite the significant debate on the technical specifications and the technological maturity of 5G, which are under discussion in various fora, 5G is expected to affect positively and significantly several industry sectors ranging from ICT to industry sectors such as car and other manufacturing, health and agriculture in the period up to and beyond 2020. 5G will be driven by the influence of software on network functions, known as Software Defined Networking (SDN) and Network Function Virtualization (NFV). The key concept that underpins SDN is the logical centralization of network control functions by decoupling the control and packet forwarding functionality of the network.^NFV complements this vision through the virtualization of these functionalities based on recent advances in general server and enterprise IT virtualization. Considering the technological maturity of the technologies that 5G can leverage on, SDN is the one that is moving faster from development to production. To realize the business potential of SDN/5G, a number of technical issues related to the design and operation of Software Defined Networks need to be addressed. Amongst them, SDN/5G security is one of the key issues, that needs to be addressed comprehensively in order to avoid missing the business opportunities arising from SDN/5G. In this report, we review threats and potential compromises related to the security of SDN/5G networks. More specifically, this report contains a review of the emerging threat landscape of 5G networks with particular focus on Software Defined Networking. It also considers security of NFV and radio network access.^To provide a comprehensive account of the emerging threat SDN/5G landscape, this report has identified related network assets and the security threats, challenges and risks arising for these assets. Driven by the identified threats and risks, this report has also reviewed and identified existing security mechanisms and good practices for SDN/5G/NFV, and based on these it has analysed gaps and provided technical, policy and organizational recommendations for proactively enhancing the security of SDN/5G.

The software and networking industry is experiencing a rapid development and deployment of Network Functions Visualization (NFV) technology, in both enterprise and cloud data center networks. One of the primary reasons for this technological trend is that NFV has the capability to reduce CAPEX and OPEX, whilst increasing networking service efficiency, performance, agility, scalability, and resource utilization. Despite such well-recognized benefits, security remains a major concern of network service providers and seriously impedes the further expansion of NFV. This book is therefore dedicated to investigating and exploring the potential security issues of NFV. It contains three major elements: a thorough overview of the NFV framework and architecture, a comprehensive threat analysis aiming to establish a layer-specific threat taxonomy for NFV enabled networking services, and a series of comparative studies of security best practices in traditional networking scenarios and in NFV, ultimately leading to a set of recommendations on security countermeasures in NFV. This book is primarily intended for engineers, engineering students and researchers and those with an interest in the field of networks and telecommunications (architectures, protocols, services) in general, and particularly software-defined network (SDN) and network functions virtualization (NFV)-based security services. Extensively studies security issues in NFV Presents a basis or guideline for both academia researchers and industry practitioners to work together to achieve secure and dependable lifecycle management of NFV based network services

Software-defined network (SDN) and network function virtualization (NFV) are two technology trends that have revolutionized network management, particularly in highly distributed networks that are used in public, private, or hybrid cloud services. SDN and NFV technologies, when combined, simplify the deployment of network resources, lower capital and operating expenses, and offer greater network flexibility. The increasing usage of NFV is one of the primary factors that make SDN adoption attractive. The integration of these two technologies; SDN and NFV, offer a complementary service, with NFV delivering many of the real services controlled in an SDN. While SDN is focused on the control plane, NFV optimizes the actual network services that manage the data flows. Devices such as routers, firewalls, and VPN terminators are replaced with virtual devices that run on commodity hardware in NFV physical networking. This resembles the 'as-a-service' typical model of cloud services in many aspects. These virtual devices can be accessed on-demand by communication, network, or data center providers.This book illustrates the fundamentals and evolution of SDN and NFV and highlights how these two technologies can be integrated to solve traditional networking problems. In addition, it will focus on the utilization of SDN and NFV to enhance network security, which will open ways to integrate them with current technologies such as IoT, edge computing and blockchain, SDN-based network programmability, and current network orchestration technologies. The basics of SDN and NFV and associated issues, challenges, technological advancements along with advantages and risks of shifting networking paradigm towards SDN are also discussed. Detailed exercises within the book and corresponding solutions are available online as accompanying supplementary material.

This thesis is intended to explore security issues in the virtualized and software-defined world, and starts with two important hypotheses: (1) SDN and NFV offer plenty of opportunities for us to rethink security management in the new networking paradigms; (2) both legacy and new security threats and vulnerabilities in NFV/SDN enabled environments need to be sufficiently addressed in order to pave the way for their further development and deployment. To validate the hypotheses, we carry out an in-depth study on NFV/SDN from security perspective, including its architecture, management and orchestration (MANO) framework, and use cases, leading to two major contributions, (1) a security management and orchestration framework (called SecMANO) based on NFV MANO, which has the potential to manage a set of policy-driven security mechanisms, such as access control, IDS/IPS, network isolation, data protection; (2) a comprehensive threat analysis on five NFV use cases and the state-of-the-art security countermeasures, resulting in a NFV layer-specific threat taxonomy and a set of security recommendations on securing NFV based services.We believe that both of the two contributions lay down a foundation for security research in NFV/SDN domain. In particular, based on the two contributions, we further develop a security orchestrator as an extension of available NFV orchestrator, with an objective to enabling the basic security functions to be effectively orchestrated and provided as on-demand services to the customers, meanwhile allowing high-level security policies to be specified and enforced in a dynamic and flexible way. Specifically, a software-defined access control paradigm is implemented and prototyped with OpenStack and Tacker (a NFV orchestrator using TOSCA model), which allows the security administrators to dynamically customize the access control models and policies for different tenant domains, eventually achieving flexible and scalable protection across different layers and multiple cloud data centers. Both prototype of concept and real-life experiments on testbed have been carried out, clearly demonstrating the feasibility and effectiveness of our security orchestrator.In addition, as our NFV cross-layer threat taxonomy indicates, a large set of novel threats will be introduced, among which VNF (Virtualized Network Function) is a unique and important asset that deserves careful protection. The fourth contribution of this thesis is therefore devoted to achieving secure and dependable SFC (Service Function Chaining) in NFV and SDN environment. Specifically, an identity-based ordered multisignature scheme called SecSFC is designed and applied to ensure that, (1) each service function involved in a particular service chain is authenticated and legitimate; (2) all the service functions are chained in a consistent, optimal, and reliable way, meeting with the pre-defined high-level specifications like VNF Forwarding Graph. Both theoretical security analysis and experimental results demonstrate that our scheme can effectively defend against a large set of destructive attacks like rule modification and topology tempering, moving an important step towards secure and dependable SFC. Importantly, the signature construction and validation process is lightweight, generating compact and constant-size keys and signatures, thereby only incurring minimal computational overhead and latency.
