As with any new technology, vulnerabilities in 5G are to be expected. To help find these vulnerabilities, developers will need an entire suite of security processes and tools in place to conduct tests at all layers of the 5G network.
Fuzz testing is one of the many security testing solutions development organizations should consider. Fuzzing complements other security testing techniques in that it’s designed to find unknown vulnerabilities, whereas others are geared toward published weaknesses and vulnerabilities.
Fuzzing is well established as an excellent technique for locating vulnerabilities in software. The basic premise is to deliver intentionally malformed input to the target software and detect failure. Fuzzing is a crucial tool in software vulnerability management, both for organizations that build software and systems and for organizations that use them.
Fuzz testing will be a primary testing technique to find unknown vulnerabilities in 5G systems that might incorporate unique software in the IP, transport, and application layers.
But whatever tools developers use in testing their 5G infrastructure, services, and devices, they won’t be able to address them all on their own. Developers must work closely with 5G network providers to ensure end-to-end security ranging from applications, devices, and services to the IP layer and core cellular infrastructure.
