US Agencies Publish Security Guidance on Implementing Open RAN Architecture


A general-purpose document titled Open Radio Access Network Security Considerations, the guidance is based on current knowledge and recommended practices and should apply to a variety of industries.

“Open RAN is the industry term for the evolution of traditional RAN architecture to open interoperable interfaces, virtualization, and big data and AI-enabled intelligence,” the document reads.

An Open RAN architecture, CISA and the NSA explain, opens the door to cloudification and virtualization, while promoting ‘increased competition, vendor diversity, and innovation’ by creating a multi-vendor ecosystem.
