“…In fact, these approaches should be more accurate and practical to operate the network resources and large data generated in 5G and to meet the needs of both users and operators [4,28]. Artificial Intelligence (AI) has the potential to deliver and operate new services with different and various requirements on top of the future network architecture.…”

“…Security becomes a fundamental feature of the design and operation in the 5G network. In fact, 5G must manage and provide solutions to have high-level security [28]. Moreover, the IDSs implemented in current cellular become obsolete and it will be unable to effectively detect new types of intrusion.…”

5G cellular networks are expected to be the key infrastructure to deliver the emerging services. These services bring new requirements and challenges that obstruct the desired goal of forthcoming networks. Mobile operators are rethinking their network design to provide more flexible, dynamic, cost-effective and intelligent solutions. This paper starts with describing the background of the 5G wireless networks then we give a deep insight into a set of 5G challenges and research opportunities for machine learning (ML) techniques to manage these challenges. The first part of the paper is devoted to overview the fifth-generation of cellular networks, explaining its requirements as well as its key technologies, their challenges and its forthcoming architecture. The second part is devoted to present a basic overview of ML techniques that are nowadays applied to cellular networks. The last part discusses the most important related works which propose ML solutions in order to overcome 5G challenges.

Multi-party and multi-layer nature of 5G networks implies the inherent distribution of management and orchestration decisions across multiple entities. Therefore, responsibility for management decisions concerning end-to-end services become blurred if no efficient liability and accountability mechanism is used. In this paper, we present the design, building blocks and challenges of a Liability-Aware Security Management (LASM) system for 5G. We describe how existing security concepts such as manifests and Security-by-Contract, root cause analysis, remote attestation, proof of transit, and trust and reputation models can be composed and enhanced to take risk and responsibilities into account for security and liability management.

Although 5G (fifth generation) networks are still in the realm of ideas, their architecture can be considered as reaching a forming phase. There are several reports and white papers which attempt to precise 5G architectural requirements presenting them from different points of view, including techno-socio-economic impacts and technological constraints. Most of them deal with network slicing aspects as a central point, often strengthening slices with slice isolation. The idea of isolation in the network is not new. However, currently considered technologies give new capabilities that can bring added value in this field. The goal of this paper is to present and examine the isolation capabilities and selected approaches to its realization in network slicing context. As the 5G architecture is still evolving, the specification of isolated slices operation and management brings new requirements that need to be addressed, especially in a context of end-to-end (E2E) security. Thus, an outline of recent trends in slice isolation and a set of challenges are presented. The challenges, if properly addressed, could be a step from the concept of 5G networks to proof-of-concept solutions which provide E2E user's security based on slices isolation. Among other things, the key features are proper slice design and establishment, security at interfaces, suitable access protocols, correct virtual resources sharing, and an adaptable management and orchestration architecture (MANO). In conclusion of the paper, short outlines of two of the main secure isolation challenges are given: a proper definition of isolation parameters and designing suitable MANO system. which is close to end users and ensuring an end-toend security services chain realized by virtualized open access physical layer security (PLS). These novel crosslayer approaches to security address such areas as: data confidentiality, data integrity, provider's resources isolation, and authentication and authorization. The security aspects of 5G networks are discussed in 5G-ENSURE project [3]. Main goals of the initiative focus on developing non-intrusive security and privacy mechanisms, which will ensure the following: AAA services, privacy, trust, network management and monitoring, and virtualization isolation for the core 5G architecture. Within the project, the 5G security testbed with proposed security components was demonstrated. The 5G NORMA (Novel Radio Multi-service adaptive network Architecture) [4] project has the key objective to develop a novel, adaptive, and future-oriented 5G mobile network architecture. The created architecture should provide network customizability and, at the same time, ensure meeting requirements associated with rigorous performance, energy saving, cost
