AI-ML Native Security (5G/6G Networks)
As telecommunications networks transition to 6G / IMT-2030, the control plane shifts from static rules to Machine Learning (ML) models. itu-t Series Y.3170 defines the architectural and security frameworks for these AI-Native networks.
🏛️ Intelligence Levels (Y.3173)
The security of an AI-Native network is defined by its Intelligence Level, ranging from human-manual to fully autonomous.
| Level | Name | Security Autonomy |
|---|---|---|
| L1 | Manual | Human-driven patching and config. |
| L2 | Assisted | AI identifies anomalies; human approves fix. |
| L3 | Conditional | AI fixes known threats; human reviews logs. |
| L4 | High | AI performs proactive threat-hunting; human-off. |
| L5 | Fully Autonomous | Self-healing, self-defending network (Y.3181). |
📑 Technical Mappings
| Recommendation | Technical Scope | Security Mapping |
|---|---|---|
| Y.3172 | ML Shared Framework | Common mapping of ML Pipelines to 5G slices. |
| Y.3173 | Intelligence Evaluation | Framework for auditing the Security Autonomy (L1-L5). |
| Y.3181 | ML-based Operations | Requirements for Autonomous Remediation of threats. |
| X.1051 (AI-Ext) | AI Governance | Mapping the Risk Management of AI in Telco. |
| Y.3175 | ML Model Management | Securing the Model-as-a-Service (MlaaS) infrastructure. |
🧠 Security Orchestration (Y.3181)
- Model Robustness: Ensuring the ML-controller is resilient to Adversarial Noise.
- Data Integrity: Protecting the Training Data from poisoning (Series-X.10x).
- Autonomous Response: Implementing a "Closed-Loop" security remediation cycle (Detection -> Analysis -> Action -> Verification).
- Explainability (XAI): Requirements for the AI to provide a "Forensic Trace" of why a security decision was made.

📋 Field Audit Checklist (AI-Native)
[ ]Model Resilience: Has the ML model been tested against adversarial perturbation (e.g., FGSM or PGD attacks)?[ ]Closed-Loop Isolation: Is the autonomous remediation logic (L4/L5) isolated from the core Control Plane (CP) to prevent cascading failures?[ ]Data Lineage: Is there a verified audit trail for the training datasets used in security-critical network functions?[ ]Explainability (XAI): Can the AI module provide a human-readable justification for automatically blocking a signaling peer?[ ]Drift Detection: Is there an automated monitor for "Security Performance Drift" in the ML models?
