rApp

In telecom networks, an rApp is an application running on the Non-Real-Time RIC within the SMO that performs longer-loop optimization and policy generation for the RAN, typically over the A1 and O1 interfaces. rApps handle tasks such as configuration management, AI-driven optimization, and large-scale analytics.

rApp in context

The radio access network is the layer where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations, downgrade attacks and jamming, and defenses hinge on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

Moving network functions off dedicated hardware into NFV, Kubernetes and Open RAN reshapes the threat model. Isolation now depends on hypervisor, container and service-mesh controls, and supply-chain security around images, Helm charts and RIC xApps becomes as important as protocol-layer defenses.

To place rApp in the wider telecom-security picture, review RIC, SMO, Data Localization, RRH, SBOM and xApp.
