Causal Deep Learning for Enhancing Explainability in 6G Network Edge Intelligence Anomaly Detection
Our deep dive into recent advancements reveals a breakthrough in AI-driven network security. This analysis explores how Causal Deep Learning (CausalDL) addresses critical challenges in 6G Network Edge Intelligence (NEI), offering unprecedented explainability and robustness in anomaly detection.
Executive Summary
This study introduces an innovative framework for anomaly detection that integrates CausalDL to address the explainability challenges in identifying anomalies within 6G NEI networks. This methodology starts with the use of Random Fourier Features (RFF) and causal interventions to estimate feature independence and precise effect sizes, subsequently employing these estimates to generate adversarially synthesized, balanced datasets via Generative Adversarial Networks (GANs) for training purposes. Long Short-Term Memory (LSTM) units capture prolonged dependencies in network traffic, filtering out noise and thereby providing causally explainable insights. The system's efficacy is empirically validated, with improvements in explainability and reductions in root-cause localization time, establishing a new cybersecurity paradigm for 6G edge intelligence.

Conventional ML struggles with transparency in 6G NEI anomaly detection. CausalDL uses causal inference to establish direct cause-effect relationships, offering clear, interpretable insights into why an anomaly occurred, fostering trust in AI-driven cybersecurity decisions.
By integrating Random Fourier Features (RFF) for decorrelation and Generative Adversarial Networks (GANs) for synthetic data generation, CausalDL significantly enhances anomaly detection accuracy, especially for rare or novel attack types in complex 6G environments. Sample weighting further refines the model's focus on critical causal features.
The framework leverages LSTM networks' ability to handle sequential data and temporal patterns efficiently. While demanding for training, the RFF preprocessing and targeted causal interventions streamline the learning process, making the detection robust for large-scale, real-time 6G NEI operations.

Case Study: DDoS Attack Detection in 6G NEI
In a simulated 6G NEI environment, traditional anomaly detection systems identified a surge in network traffic as a potential DDoS attack, but couldn't explain why or what specific factors were driving it beyond simple correlations. Our CausalDL framework, however, not only detected the DDoS attack with high accuracy but also identified the specific network flow features (e.g., Total Fwd Packets, Fwd Packets/s) that had a direct causal impact on the anomaly. This allowed operators to rapidly pinpoint the compromised services and affected edge devices, reducing mean time to resolution by over 50% compared to traditional methods. The explainable insights enabled targeted mitigation strategies instead of broad, potentially disruptive, network-wide interventions.
