## Description

Security Onion is a security information and event management platform and network security monitoring suite. It functions as an intrusion detection system and a network traffic analysis tool designed to identify malicious activity and network intrusions through signature-based detection and host-based monitoring.

The platform integrates a security case management system to organize investigations by tracking detections and grouping related security events. It provides capabilities for full packet capture, network metadata extraction, and the collection and indexing of security logs from diverse sources.

The system covers a broad range of security operations, including security incident investigation, threat hunting workflows, and security log aggregation. It utilizes a unified web console to analyze security events and alerts, and incorporates artificial intelligence to assist in the investigation of security data.
