📋 Audit Checklist: itu-t Y.4401 IoT Functional Security

Field Security Audit // Node_Operational
Completion_Index0%

Device Registration & Authentication

item_em-0

Lighthouse/Sparkle Support: Are devices using lightweight cryptography for authentication (ECC-256 or equivalent)?

item_em-1

Secure Boot & Hardware Trust: Do devices implement a Hardware Root of Trust (e.g., TPM, Secure Element)?

item_em-2

Identity Integrity: Are device IDs (IMEI, EUI-64) cryptographically bound to the authentication token?

Payload & Interface Protection

item_em-3

Southbound Interface (D-IF): Is payload data encrypted at the application layer (AES-128 GCM)? Audit the use of DTLS (Datagram TLS) for constrained networks (MQTT/NB-IoT).

item_em-4

Northbound API Security: Are the APIs exposed to 3rd-party application providers (Y.4401 N-IF) secured with OAuth 2.0/OIDC? Is there rate-limiting to prevent mIoT DDoS attacks on the core?

Management and Orchestration (M-Plane)

item_em-5

Lifecycle Management: Audit the OTA (Over-the-Air) firmware update mechanism. Is it signed?

item_em-6

Configuration Integrity: Are devices managed via secure protocols (LwM2M with DTLS or TR-069 with HTTPS)?

item_em-7

Isolation: Are IoT traffic slices logically isolated at the PGW/UPF level?

Global Compliance (3GPP/GSMA)

item_em-8

GSMA CLP.11 Alignment: Does the deployment meet the GSMA IoT Security Guidelines?

item_em-9

Privacy Compliance: Are sensors anonymizing PII before transmission to the cloud?
