In present digital societies, telecommunication networks provide connectivity, which is crucial for the operation and management of many other critical infrastructures and services such as healthcare, industrial operations and public safety. This situation is expected to be exacerbated with the incorporation of the Fifth Generation (5G) wireless services such as enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and massive machine-type communications (mMTC). Security and Privacy have become the primary concern in 5G and Beyond 5G (B5G) network as risks can have high consequences. Thus, this tutorial will explain the potential security attacks and breaches of privacy that the emerging 5G networking paradigm is facing. It will present a comprehensive detail on the core and enabling technologies, which are used to build the 5G security model; network softwarization security, PHY (Physical) layer security and 5G privacy concerns, among others. Moreover, the tutorial will explain the possible ways of developing novel security and privacy solutions to protect the 5G telecommunication networks to strengthen critical infrastructures. Finally, future directions and open challenges will be discussed to encourage future research.
