Considerations and strategies for Open RAN cyber security

This report explores the cyber-security implications of adopting Open RAN architecture instead of traditional physical RAN and closed vRAN alternatives. It examines the components and features of Open RAN that exacerbate RAN security challenges, and provides recommendations for how telecoms operators, Open RAN vendors and the wider Open RAN ecosystem can mitigate them. The report also discusses the potential cyber-security benefits that can emerge from adopting Open RAN architecture and considers how these benefits can best be realised.
