CISA and the National Security Agency (NSA) have published Open Radio Access Network Security Considerations. This product—generated by the Enduring Security Framework (ESF) Open Radio Access Network (RAN) Working Panel, a subgroup within the cross-sector working group—assessed the benefits and security considerations associated with implementing an Open RAN architecture. Focusing on current designs and specification standards, the ESF Open RAN Working Panel examined how security compares with, and is distinct from, traditional, proprietary RANs.
CISA encourages users, network operators, vendors, and stakeholders to review the considerations. For more information, see the ESF’s Open Radio Access Network Security Considerations, peruse CISA’s 5G Library, and visit Securing 5G Open RAN Architecture from Cybersecurity Risks.
