Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Traditional ML algorithms often struggle with high computational overhead, a lack of transparency (being 'black boxes'), and non-determinism, making them less suitable for resource-constrained IoT devices. They also typically focus on specific attack types and lack causal understanding, leading to potential false positives/negatives.
Traditional ML vs. Hybrid FCM for IDS
| Feature | Traditional ML | Hybrid FCM |
|---|---|---|
| Computational Cost | High, Opaque | Low, Efficient (O(n.log n) / O(n.k)) |
| Interpretability | Black-box, Post-hoc XAI needed | Transparent (FCM graph, explicit weights) |
| Resource Constraints | Not well-suited for IoT | Well-suited (low memory footprint) |
| Determinism | Randomness in some algorithms | Deterministic |
| Causal Understanding | Limited, implicit | Explicit (FCM edges model relationships) |
Fuzzy Cognitive Maps (FCMs) model hazy causal relationships between 'concepts' or 'features' as a fuzzy digraph. Directed edges (weights) quantify the influence of one feature on another, allowing for complex inter-dependencies to be modeled. The dynamic approach iteratively updates feature values, making FCMs powerful for forecasting and classification without a hidden layer, ensuring full transparency.

Packet Classification (Attack/Benign)
Our hybrid method combines ML feature selection (like SelectKBest) to derive transparent input feature weights with FCM classification. An automated AUC-based threshold computation ensures optimal classification. This results in a simple, reliable, and transparent intrusion detection system with a low memory footprint, ideally suited for resource-constrained IoT devices.

Why SKB-C/C2 Excel in Hybrid DDoS Detection
Our experiments show that statistical feature selection algorithms like SelectKBest-Classification (SKB-C) and SelectKBest-ChiSquared (SKB-C2) consistently yield the best results when paired with FCM. These methods are inherently simple, transparent, and effective at quantifying the direct influence of features on the output. Their low computational overhead and deterministic nature make them superior for resource-constrained environments compared to more complex, black-box ML algorithms, ensuring reliable and consistent DDoS attack detection.
