How to Build a Home Security Operations Center Using Free Open-Source Tools

A developer has published a guide detailing how to build an enterprise-grade Security Operations Center (SOC) on a home network using entirely open-source software. The core stack includes Suricata for signature-based intrusion detection, Zeek for comprehensive network activity logging, and Wazuh for endpoint monitoring and vulnerability scanning. ntopng provides real-time human-readable traffic analysis, while Elasticsearch serves as the central data layer for indexing and querying all collected security data. The guide emphasizes understanding each tool's role rather than blindly copying steps, arguing that architecture matters more than expensive hardware. It can be run on a standard laptop or desktop using VirtualBox, with an optional migration to Proxmox for always-on deployment.
