“…These APIs are potential sources of security threats [20]. In a cloud environment, Virtual Network Functions (VNFs) may lead to security threats like confidential data leakage, malicious loops, network failures, and abuse of hypervisor, one of the architectural components of NFV [21]. Hypervisor domain can face unauthorized access and data leakage [22].…”

Growing client population, ever-increasing service demand, and complexity of services are the driving factors for the mobile operators for a paradigm shift in their core technology and radio access networks. 5G mobile network is the result of this paradigm shift and currently under deployment in many developed countries such as United States, United Kingdom, South Korea, Japan, and China-to name a few. However, most of the Least Developed Countries (LDCs) have very recently been implemented 4G mobile networks for which the overall role out phase is still not complete. In this paper, we investigate how feasible it is for LDCs to emphasize on a possible deployment of 5G networks at the moment. At first, we take a holistic approach to show the major technical challenges LDCs are likely to face while deploying the 5G mobile networks. Then we argue that various security aspects of 5G networks are an ongoing issue and LDCs are not technologically competent to handle many security glitches of 5G networks. At the same time, we show that most of the use cases of 5G networks are not applicable in the context of many LDCs (at least at the present time). Finally, this paper concludes that the start of the 5G network deployment in LDCs would take much longer time than expected.

The current domestic cloud platform, including China Mobile's public cloud and DICT private cloud, cannot satisfy the needs of high-end clients in many industries, such as ''government, public security, education, healthcare, finance, transportation, power, and large enterprises''. Those specifics are: customization, ''data cannot be stored out of the local city'', ''must meet the Chinese safety standard of Classified Protection of Cybersecurity Version 2.0 Third Level (CPCv2.0 Lv.3) '', strong isolation and exclusiveness. Therefore, Industry-specific Cloud Platform built this time can provide the cloud resources and security services, facing to above eight industries. Thus selecting IDC (Integrated Data Center) to build an Industry-specific Cloud Platform, in which network management area, maintenance area and computing & storage area can be deployed locally. The structure adopts SDN architecture and related supporting SDN equipment, which can also meet the platform's CPCv2.0 Lv.3 requirements, while also providing external security services. At its root, it can solve the needs of high-end clients in eight industries for cloud resources and security services.

“…Their location often depends on the requirements of latency or bandwidth limits, so they are hosted where necessary (see [136]) or for economic purposes where the resources are available. What is essential, such relocation is not indifferent to security level because it indicates new threats [137] to VNFs which were usually not present in the legacy architecture and had additional perimeter protection.…”

5G is the fifth-generation cellular network satisfying the requirements IMT-2020 (International Mobile Telecommunications-2020) of the International Telecommunication Union. Mobile network operators started using it worldwide in 2019. Generally, 5G achieves exceptionally high values of performance parameters of access and transmission. The application of edge servers facilitated the implementation of such requirements of 5G, which resulted in 5G MEC (Multi-access Edge Computing) technology. Moreover, to optimize services for specific business applications, the concept of 5G vertical industries has been proposed. In this paper, we study how the application of the MEC technology affects the functioning of 5G MEC-based services. We consider twelve representative vertical industries of 5G MEC by presenting their essential characteristics, threats, vulnerabilities, and known attacks. Next, we analyze their functional properties, give efficiency patterns and identify the effect of applying the MEC technology in 5G on the resultant network's quality parameters to identify the expected security requirements. Finally, we identify the impact of classified threats on the 5G empowered vertical industries and identify the most sensitive cases to focus on their protection against network attacks in the first place.
