A Cybersecurity Architecture to Secure the 5G Network through Modeling & Simulation
Open Access DepositedThe fifth-generation technology standard for mobile networks (5G) introduced a massive increase in capability due to the increased use of Internet of Things devices. However, implementing additional untrusted technology, such as IoT devices, exposes the infrastructure to unsecure hardware and software. As a result, the attack surface of the 5G mobile network has increased after transitioning from LTE to the 5G standard. Three research questions and hypotheses were composed to evaluate the architectural design of the network for the healthcare use case. The Perimeter Security, Zero Trust Microsegmentation, and Non-Standalone Models were designed in the Cyber Virtual Assured Network simulator and compared so that the researcher can identify the ideal architectural solution. The researcher composed three research questions that are concerned with the effectiveness of the 5G topology design, the security resilience of a simulated cyber architecture, and architecture model comparison in network latency performance. For the hypotheses, the author conducted research to substantiate that the User Equipment-New Radio is the most effective topology in completing the scope of work, CyberVAN can enhance the security resilience of the 5G network, and the Perimeter Security Model performs best in network latency. After comparing the models, the researcher concluded the Zero Trust Microsegmentation Model is the most cyber-resilient architecture for the healthcare use case that performed well in network latency performance. Lastly, the author recommends future work for other researchers who show interest in this research area.
