It is important that 5G and next-G networks providing critical infrastructure and mission critical use cases are built with a Zero Trust Architecture (ZTA) to protect against external and internal threats. ZTA is the evolution of the zero trust concept to a concrete plan based upon multi-layered security controls that provide confidentiality, integrity, availability, authentication, and authorization protections from internal and external threats. The O-RAN ALLIANCE is committed to pursue a ZTA through stages of a maturity model that achieve a strong security posture to protect against evolving threats.
