Riassunto
The evolution of mobile networks toward highly software-defined architectures introduces new testing challenges, particularly as 5G systems become foundational to critical infrastructure. These challenges are amplified in multi-vendor environments where access to internal system details is restricted. This work explores for protocol fuzzing — evaluating how networks handle malformed or unexpected inputs — as an effective method for uncovering vulnerabilities under such constraints. A Black-Box testing framework is developed to analyze network robustness by dynamically mutating protocol messages exchanged across the interfaces between emulated Radio Access components and Core Network Functions. The approach is designed to assess multiple critical functions, demonstrating its adaptability across different network layers. Experimental validation confirms the framework’s ability to identify implementation flaws, reinforcing the value of adversarial testing in real-world deployments.
