Provider admission, inside Protocol & Grid: 5G system security, network product security assurance, open RAN security, 5G security reference practice and more. Every item is traced to its specification, from 3GPP TS 33.501 (Rel-18) to 3GPP TS 33.117 (SCAS general requirements), and runs on the open Observatory Protocol. [Plan with us](https://observatory.global/contact/) Architecture [The protocol](https://observatory.global/protocol/specification/) **Technologies**: 9 **At the frontier**: 0 **Protocol functions**: 5 of 8 **Industries served**: 6 Reference design, drawn to scale · drag to turn · hover a part **01** What it is ## 5G and wireless security. How every node proves what it is and what it runs, how links and keys are protected, how software is traced to its source, how personal data is minimised, and how incidents are found and handled. Each technology below carries what it is, what we do with it, and the standard it is drawn against. Security, identity and trust ### 5G system security Authentication, key hierarchy, subscriber privacy and network domain security for 5G. We design, integrate and operate. 3GPP TS 33.501 (Rel-18) Security, identity and trust ### Network product security assurance Security test specifications and assessment schemes for 5G network functions. We design and integrate. 3GPP TS 33.117 (SCAS general requirements) · GSMA NESAS Security, identity and trust ### Open RAN security Security requirements for open fronthaul, near-real-time RIC and O-Cloud interfaces. We design and integrate. O-RAN WG11 security specifications Security, identity and trust ### 5G security reference practice Practical guidance for securing 5G deployments. We design. NIST SP 1800-33 (5G cybersecurity) Security, identity and trust ### LPWAN security Session keys, join servers and key provisioning for LoRaWAN and cellular IoT. We design, integrate and operate. LoRaWAN L2 1.0.4 (TS001-1.0.4) · LoRaWAN Backend Interfaces (TS002) Security, identity and trust ### RF jamming and rogue emitter detection Spectrum monitoring that flags jamming, rogue base stations and unauthorised links. We design, integrate and operate. ITU-R Handbook on Spectrum Monitoring Security, identity and trust ### Industrial security programmes Security management system for asset owners of control and monitoring systems. We design and operate. IEC 62443-2-1 Security, identity and trust ### System and component security levels Security requirements for systems and components at target security levels. We design and integrate. IEC 62443-3-3 (system requirements) · IEC 62443-4-2 (component requirements) Security, identity and trust ### Secure development lifecycle Secure product development practice for anything shipped to sites. We design. IEC 62443-4-1 · NIST SP 800-218 (SSDF) **02** Architecture ## Where it sits, and what it speaks. Provider admission draws on 1 domain and 8 layers of the spectrum; the highlighted layers carry this area. It speaks 5 of the protocol's 8 core functions. Device identity and attestation 8 PKI, secure boot and updates 7 Zero trust and network security 7 5G and wireless security 6 OT security and software supply chain 9 Privacy and data protection 7 Keys, cryptography and post-quantum migration 9 Monitoring, incident response and governance 8 01**Join** Identity, attestation quote, signed policy. 02**Admit** Admitted for a stated scope, nothing wider. 03**Describe** What, where, how and by whom, with calibration. 04**Time** One clock across the grid, with its error bound. 05**Observe** Every value with quality and provenance. 06**Qualify** Tested against the specification, state on record. 07**Federate** Signed exchange across grids and trust domains. 08**Orchestrate** Software and configuration by signed plan. **03** On the grid ## Every site joins one observing grid. The open networks on the grid today, over real relief and the geodesic cells we count them into. A site built here enrols into the same grid. **04** In the field ## Where this runs, sector by sector. 6 deployment scenarios from the sector research that rely on provider admission.
