Formalize the integrated architecture and security of I-nRT RIC with SON, MEC, and slicing

Formalize the integrated architecture, interfaces, and security requirements of the proposed Integrated Near-Real-Time RIC (I-nRT RIC) that consolidates O-RAN with Self-Organizing Networks (SON), Multi-Access Edge Computing (MEC), and network slicing, addressing the increased attack surface and enabling centralized, robust security mechanisms.

Background

The authors discuss a high-level integration concept where an Integrated nRT RIC (I-nRT RIC) coordinates O-RAN with SON, MEC, and network slicing, aiming to streamline control and monitoring functions.

They note that the nature of these integrated systems is not yet fully defined, and that the integration may increase the attack surface. A formal specification and security framework are needed to guide implementation and mitigate risks.

References

Furthermore, as the concept is presented at a high level and the nature of these systems is not yet fully defined, security considerations should be incorporated into the design and development phases.
