As 5G begins to be widely available, several things will happen. Firstly, in addition to exponentially faster speeds, 5G will also introduce greater capacity, reduced latency, and more flexible service delivery. This will enable organizations to provide better content, more real-time transactions, and much richer user experiences across entertainment and commercial activities.
Lower latency and highly reliable connections will then enable greater edge-based computing without the need for nearby data centers to support latency-sensitive transactions and workflows. Instead, by provisioning computing services closer to end-users, 5G servers will acquire enough intelligence to act as application servers — supporting a wide array of edge-based applications, transactions, and business processes. Eventually, when 5G speeds and capacity are combined with the unprecedented power of edge devices, we will see the creation of new edge-based networks that can share and process information locally, as well as cloud-based resources.
Because these edge-based computing resources will be highly distributed, they will need to be interconnected using enterprise-grade applications and high-speed connections to ensure that the huge volumes of data, workflows, and transactions they will create are tracked and analyzed in real-time. 5G networking will also offer application developers and content providers cloud computing capabilities and an IT service environment at the edge of mobile networks to create new services. However, these open, hyperconnected edge networks will also have serious implications for how devices, data, applications, and workflows can be managed, along with how they connect to traditional and cloud-based networks.
5G will also have an impact far beyond interconnecting endpoint devices. IoT devices will be enlisted to track other devices and users, monitor inventory, gather user and device information, and provide real-time data that can impact everything from agile application development and manufacturing floors to managing and coordinating resources in highly connected environments such as smart cities.

The following paper presents challenges and recommendations regarding 5G-IoT scenarios: Conference Paper Security Challenges and Recommendations in 5G-IoT Scenarios
Abstract: The fifth-generation (5G) mobile communication systems are already a reality. This communication technology can increase and simplify the adoption of the Internet of Things (IoT) applications (e.g., industrial IoT), given that it will provide the means to connect up to one million devices in a squared kilometer. Many of these applications can generate sensitive data, which requires the adoption of security mechanisms, and these mechanisms must consider the computational limitations of the devices. Considering that IoT devices under security attacks can access the 5G infrastructure, this paper presents recommendations and challenges regarding security in IoT devices. It also presents a threat model and a few common attacks, classifying them with the STRIDE model and CVSS and discussing how they can impact the 5G infrastructure .
We recently submitted a systematic literature review, related to that paper, to a journal.
1. Securing 5G wireless networks: 5G networks will open up many new attack vectors, and new security measures must be put in place to protect them.
2. Securing the edge devices: With the increasing number of edge devices, it is critical to ensure that the data exchanged between them is secure and protected from potential malicious actors.
3. Securing data transmission: As data is transmitted across multiple networks and devices, security measures must be implemented to ensure data privacy and integrity.
4. Securing FogEdge computing systems: FogEdge computing systems must be secured from potential malicious actors, and measures must be taken to ensure that data is not exposed to unauthorized access.
5. Securing IoT devices: IoT devices pose unique security challenges, as they can easily be hacked and used to gain access to sensitive data or networks. Security measures must be put in place to protect them.
