In today's digital era, the complexity and frequency of cyberattacks continue to rise. Traditional rule-based Intrusion Detection Systems (IDS) can identify known threats but struggle with zero-day vulnerabilities, variant malware, and Advanced Persistent Threats (APT). Meanwhile, enterprise network logs and traffic data are exploding, making manual analysis unfeasible.

AIDefenseX was born to address these issues. By integrating machine learning technology with mature open-source security tools, it builds an intelligent intrusion detection and prevention platform to enhance threat detection accuracy and response speed.

AIDefenseX adopts a layered architecture design, integrating data collection, intelligent analysis, and active defense:

Data Collection Layer: Wazuh Security Monitoring

Wazuh collects security event logs from end devices and servers, providing raw data for subsequent analysis.

Network Detection Layer: Suricata Threat Detection

Suricata monitors network traffic in real time, capturing suspicious network behaviors and attack patterns.

Intelligent Analysis Layer: Machine Learning Models

It collects multi-source data from Wazuh and Suricata, performs in-depth analysis via machine learning models to identify abnormal behaviors and potential threats—differentiated from traditional signature-based detection.

The machine learning module of AIDefenseX undertakes multiple tasks:

Anomaly Detection: Uses unsupervised/semi-supervised models (e.g., Isolation Forest, Autoencoder) to identify abnormal events deviating from normal behavior, addressing unknown attacks.

Threat Classification: Applies supervised learning models (e.g., Random Forest, XGBoost, neural networks) to classify suspicious activities and determine attack types (DDoS, port scanning, etc.).

Risk Scoring: Calculates risk scores for security events to help teams prioritize high-risk incidents.

Predictive Defense: Analyzes time-series features of attacks to predict next steps and enable proactive defense.

Data Preprocessing

Unifies and cleans heterogeneous data from Wazuh and Suricata, including log parsing, field extraction, timestamp alignment, and feature standardization.

Model Training & Update

Supports incremental learning and online updates to adapt to environmental changes and new threats; addresses class imbalance issues (normal samples far outnumber attack samples).

Real-Time Inference Optimization

Meets real-time requirements in production environments via model quantization, batch inference, or dedicated hardware acceleration.

Visualization & Alerts

Provides an intuitive dashboard to display security posture, supporting multi-channel alerts (email, Slack, Webhook, etc.).

AIDefenseX applies to multiple scenarios:

Enterprise Network Protection: Deployed at internal network boundaries and key segments for 7×24 monitoring and protection.

Cloud Environment Security: Adapts to cloud-native architectures to protect cloud servers, containers, and microservices.

Industrial Control Systems: Deployed in OT networks to protect critical infrastructure.

Security Operations Center Enhancement: Assists SOC teams in reducing alert fatigue and improving analyst efficiency.

AIDefenseX represents a trend in the cybersecurity field: deep integration of artificial intelligence and traditional security tools, using machine learning to detect complex threats, and leveraging the open-source tool ecosystem to reduce deployment costs.

In the future, with the development of large language models (LLMs) and deep learning, intrusion detection systems are expected to make breakthroughs in interpretability, adaptability, and automated response, building a more robust security defense line.
