5G core networks, with their promise of tailored connectivity and enhanced capabilities, have become increasingly popular across industries from diverse sectors ranging from manufacturing, healthcare and smart cities to defense networks. With the integration of mission-critical systems and sensitive data transmission, organizations face an urgent need to fortify their 5G core networks against evolving cyber threats. One of the critical challenges here lies in the shortage of expertise and the requisite skillset to effectively secure 5G networks. This gap manifests in various stages, from the initial deployment phase to ongoing testing and adaptation. The need for specialized knowledge in mobile network attacks, secure deployment practices, and testing methodologies becomes apparent and our training is your key to mastering the art of safeguarding 5G networks. This training program is not just about theory; it's a journey through practical application and real- world scenarios. Get ready to immerse yourself in hands-on exercises, simulations, and practical demonstrations that mirror the challenges faced by 5G security professionals. The training will cover a wide range of topics, including 5G network architecture, threat modeling, risk assessment, defense-in-depth strategies and 5G security features and their role in protecting the modern day virtualized core networks against potential attacks. Through practical exercises and case studies, hackathon experiences, participants will learn about new ways to attack core networks by exploiting device and network authentication issues, vulnerabilities in network slicing, by deploying rogue network functions, container breakouts, and invesitgate the potential for data interception and manipulation. This hands-on experience is achieved entirely in an ethically controlled test environment with security testing tools and techniques, including reconnaissance, penetration testing and vulnerability scanning. The training will also cover advanced topics such as fuzzing the service based and Telecom APIs. By the end of this training, participants will be equipped with the technical expertise to design, implement, and maintain secure 5G core networks. They will have the confidence to tackle the security challenges posed by 5G technology and ensure the availability, integrity and confidentiality of their networks.
