CYBERSPACE UNLOCKED — VOLUME 4

CyberSpace Unlocked, Volume 4: The Defensive Toolkit and Home Lab

Defensive Cybersecurity Textbook & Lab Manual

Learn how to practise defensive cybersecurity without turning a home network into a testing ground. CyberSpace Unlocked, Volume 4: The Defensive Toolkit and Home Lab, guides you through building a controlled virtual environment and understanding the tools defenders use to observe, inventory and protect systems.

Explore VirtualBox virtual machines and network modes, Kali Linux and Ubuntu, Wireshark packet capture, authorised Nmap service inventory, pfSense Community Edition, Wazuh security monitoring, Greenbone Community Edition vulnerability management, Bitwarden and KeePassXC password storage, and BleachBit cleanup. Then work through 15 guided defensive lab exercises and a capstone that combines the tools in a miniature network.

This practical textbook and lab manual also includes resource-planning guidance, safe lab boundaries, troubleshooting and shutdown procedures, lab-scope and asset-inventory templates, a 20-question examination with explained answers, a glossary and an official source index. Every hands-on activity is framed around systems you own or are authorised to administer, synthetic data and appropriately isolated virtual networks. Legal examples are U.S.-focused.
