This document summarizes a student-run cybersecurity lab that was created on a limited budget. The lab uses ESXi virtualization to allow multiple students to collaborate on network penetration testing, defense, and forensics simulations. Virtual machines containing different operating systems and software can be cloned, backed up, and deleted as needed for educational exercises. The virtual network is contained within the lab environment through the use of a Pfsense firewall. This provides students hands-on experience building and securing networks while learning from mistakes in a safe environment before entering the workforce.
