Uncertainty Measurement for Anomaly Detection
Entropy quantifies the uncertainty or information content within a random variable. In network security, tracking entropy helps identify deviations from normal traffic patterns. However, traditional information entropy based solely on source IPs can be less sensitive to nuanced attacks.
Conditional Entropy (H(X|Y)) extends this by measuring the uncertainty of one variable (e.g., source IP) given another known variable (e.g., destination IP). This research shows that during a DDoS attack, the conditional entropy of source IP with respect to destination IP changes significantly, offering a more sensitive and stable indicator of malicious activity. This metric is a cornerstone of ATS-DTA's rapid first-stage anomaly detection, enabling early identification of potential threats.
Adaptive Threshold Adjustment for Dynamic Environments
The EWMA-ARIMA Adaptive Threshold Adjustment (EWAMA) module is key to ATS-DTA's flexibility. It combines the strengths of two powerful time-series models:
- Exponentially Weighted Moving Average (EWMA): Excels in real-time anomaly detection and smoothing short-term fluctuations, giving more weight to recent data.
- AutoRegressive Integrated Moving Average (ARIMA): Ideal for forecasting long-term trends and understanding seasonal patterns in network traffic.
EWAMA dynamically adjusts detection thresholds by adapting the weight (β) between ARIMA's long-term predictions and EWMA's short-term responsiveness. This ensures the system remains highly accurate and adaptable to both stable network conditions and volatile DDoS attack scenarios, significantly reducing false positives and improving detection timeliness.
Intelligent Attack Classification with Machine Learning
Following initial anomaly detection by the conditional entropy module, the Machine Learning Detection Module in ATS-DTA provides precise attack confirmation. It employs a suite of robust algorithms selected for their adaptability to diverse attack characteristics:
- Support Vector Machine (SVM): Effective for classification, robust with high-dimensional data.
- K-Nearest Neighbors (KNN): A non-parametric method well-suited for diverse attack patterns.
- Decision Tree (DT): Provides interpretability, helping to understand attack features.
- Random Forest (RF): An ensemble method that improves model stability and accuracy.
These models analyze a rich set of traffic features including Speed of Source IP (SSIP), Average Packets (AP), Standard Deviation of Packets (SDP), Average Byte Frequency (ABF), and Ratio of Flow Pairs (RFP). This multi-faceted analysis ensures high-accuracy classification, enabling timely and effective mitigation of complex DDoS attacks.

Case Study: Dynamic Adaptability in Complex Network Environments
In a simulated enterprise SDN environment experiencing fluctuating traffic patterns and diverse DDoS attack vectors, traditional static-threshold detection systems struggled with high false positive rates and missed detections. Implementing ATS-DTA, however, significantly transformed the network's defense posture. The system's EWAMA Dynamic Threshold Adjustment continuously adapted to real-time traffic changes, ensuring accurate anomaly detection without manual intervention. This adaptability resulted in a 1.91% average accuracy improvement and a 1.23% increase in precision over previous static methods, proving ATS-DTA's capability to maintain robust security even under complex and evolving attack scenarios, minimizing operational burden and maximizing defense efficacy.
