The rapid evolution of cellular network technologies, particularly the rollout of 5G, Open Radio Access Network (ORAN), and the continued dominance of 4G/LTE transforms mobile networks into a dynamic, hybrid cloud ecosystem that drives innovation and supports critical infrastructure. However, these advancements have also created expanded attack surfaces, amplified supply chain vulnerabilities, and increased operational complexity, as evidenced by recent high-profile breaches. Traditional security models can no longer address these risks, necessitating a transition to a comprehensive zero-trust security paradigm. This working group proposes to create a Zero Trust guidance for Cellular Networks, primarily focusing on securing 5G, ORAN, and 4G/LTE environments. The guidance will integrate telecom security standards with enterprise Zero Trust principles, delivering actionable solutions that are practical, implementable, and adaptable to hybrid cloud deployments.
