## Overview

This repository documents a cybersecurity homelab rather than providing executable software. Its workflow is to configure a small simulated IT environment, then apply security monitoring, vulnerability scanning, and threat simulation. The README names the components and tasks, but provides no source excerpts or detailed data-flow descriptions; aside from OpenVPN’s LDAP integration with Active Directory, relationships between components are therefore not inferred. Component paths point to the README, which documents them.

Main entry points: [`README.md`](https://github.com/birdm4nw/cybersecurity-homelab/blob/main/README.md) (OpenVPN)
