5G Network Security
Project Overview
5G has designed in security controls to address many of the threats faced in today's 4G/3G/2G networks. These controls include new mutual authentication capabilities, enhanced subscriber identity protection, and additional security mechanisms. 5G offers the mobile industry an unprecedented opportunity to uplift network and service security levels. 5G provides preventative measures to limit the impact of known threats, but adopting new network technologies introduces potential new threats for the industry to manage.
The PolySec Lab is looking at the security of the data, so phone and application usage is secured from the hackers.

Experimental Evaluation of 5G Network Fuzzers Using a Real Private 5G Network Deployment A Research Study on Cybersecurity Testing in Real-World 5G Environments Abstract: Network fuzzing is a widely adopted technique for identifying vulnerabilities within communication protocols, particularly in emerging technologies such as 5G networks. Although various fuzzing tools, including 5GReplay, Frizzer, and Fuzzowski, have traditionally been evaluated using simulated environments, their effectiveness and reliability in realistic settings remain uncertain. This research addresses this gap by experimentally evaluating the performance of these three prominent 5G fuzzers against a real-world private 5G network deployment. Our study highlights critical discrepancies between simulated environments and actual deployments, which introduce unique system-specific constraints, network complexities, and protocol behaviors not replicated in simulated scenarios. Through rigorous experimentation, we demonstrate that all three fuzzers exhibit diminished performance in real-world conditions, primarily due to their reliance on simplified assumptions inherent in simulation frameworks. These findings underscore the necessity of validating network fuzzers in realistic environments, thus informing the design and optimization of future fuzz testing methodologies and tools explicitly tailored for practical 5G network deployments.
Network-Level Penetration Testing and Network Protocol Fuzzing in a Real-World Private 5G Network Deployment: Methodologies, Findings, and Performance Evaluation A Research Study on 5G Network Security: Methodologies, Findings, and Performance Evaluation Abstract: This paper explores network-level penetration testing and protocol fuzzing applied to a real-world private 5G network deployment. It investigates critical vulnerabilities and protocol anomalies across UE, ORAN, DU, CU, and 5G Core Network (5GC) components. Findings include detailed vulnerability characterization, real-world impact scenarios, and comprehensive performance metrics. Recommendations for enhancing private 5G network security based on empirical results are provided.
