[CDP-development] New ESF Guidance for Open Radio Access Network

[Masse, Theresa]

FYSA

Today, the Cybersecurity and Infrastructure Security Agency (CISA) and National Security Agency (NSA), through the Enduring Security Framework (ESF), a cross-sector working group, published a paper titled, Open Radio Access Network Security Considerations,<https://www.cisa.gov/sites/default/files/publications/open-radio-access-network-security-considerations_508.pdf> which assesses the benefits and security considerations with implementing Open RAN architecture.



Mobile network operators provide cell services with a vast deployment of antennas and radios on cell towers connected to base station equipment. The base station equipment converts the wireless signals to data consisting of text messages, phone calls, streaming videos, and all the other pervasive applications offered today. The mobile network industry calls the radios, cell towers, and base station equipment converting wireless signals to data the Radio Access Network (RAN). This assessment considers the security of a mobile industry initiative toward an Open RAN.



In developing this paper, the ESF’s Open RAN Working Panel focused on current designs and specifications for Open RAN architectures, and considered how these security considerations compared to, or are distinct from, traditional, proprietary RANs. The ESF Working Panel also addressed the additional resources required to fulfill the vision of interoperable, multi-vendor RAN powered by cloud services and software.



This guidance in this paper is provided “as is” based on knowledge and recommended practices in existence at the time of publication document and was written for general informational purposes only. It is intended to apply to a variety of factual circumstances and industry stakeholders.
