This article introduces an intelligent intrusion detection system that integrates AI technology with the open-source Snort engine. By combining machine learning models with signature-based detection, it achieves real-time identification of network anomalies and threat early warning. This system addresses the limitations of traditional rule-based IDS in handling zero-day vulnerabilities and the high false positive rate of pure ML solutions. It uses a dual-engine architecture to balance detection accuracy and false positive control, providing a new approach for network security protection.

## Background: Ongoing Challenges in Cybersecurity

With the deepening of digital transformation, enterprises face increasingly complex cyber threats. Traditional rule-based intrusion detection systems can identify known attack patterns but struggle with zero-day vulnerabilities and variant attacks. Pure machine learning solutions, while having generalization capabilities, may produce high false positive rates, increasing the burden on security teams. Balancing detection accuracy and false positive control has become a key issue in modern IDS design.

## System Architecture: Dual-Engine Collaborative Design

This project uses an 'AI + Snort' dual-engine architecture. Snort provides a mature signature rule base and real-time traffic analysis capabilities; the machine learning module is responsible for learning unknown patterns to complement Snort's limitations in handling new threats. Core advantages: Snort responds immediately when known threats are detected; when traffic deviates from the normal baseline but does not match known rules, the AI model intervenes to analyze potential risks.

## Mechanism of the Machine Learning Model

The AI component identifies anomalies by analyzing multi-dimensional features of network traffic (packet size distribution, connection frequency, port access patterns, protocol anomalies, etc.). During the training phase, it learns statistical features of normal behavior to establish a dynamic baseline; during operation, it compares real-time traffic with the baseline and outputs an anomaly score for assessment. This method can effectively detect hidden attacks that are difficult to capture with traditional rules (such as slow scanning, data exfiltration, and APT).

## Real-Time Detection and Response Process

The detection process emphasizes low latency and high throughput: after traffic is preprocessed to extract features, it is sent in parallel to the Snort rule engine and ML inference module; the results are comprehensively evaluated through a fusion layer to output security decisions. After confirming a threat, multiple responses are supported: generating alarm logs, blocking suspicious connections, notifying the SOC, etc., to shorten the threat handling time window.

## Application Scenarios and Practical Value

It is suitable for scenarios such as enterprise intranet boundary protection, data center traffic monitoring, and cloud environment security auditing. Small and medium-sized organizations can reduce the threshold for security construction through open-source solutions; large enterprises can use it as a supplementary layer to existing architectures to enhance unknown threat perception. The combination of AI and Snort provides a feasible path for the intelligent upgrade of traditional security infrastructure, allowing ML capabilities to be introduced without replacing existing equipment.

## Summary and Outlook

AI-powered IDS represents an important development direction in network security protection. By combining rule engines with ML models, it maintains low false positives while expanding threat coverage. In the future, with the popularization of edge computing and 5G, distributed IDS will become a hot topic; how to deploy lightweight AI models on resource-constrained edge nodes while maintaining accuracy is a direction for continuous exploration.
