Project History
Enterprise Attack & Detection Cyber Range Lab
https://youtu.be/4lJtoUl9W_w?si=Q9LUF-SNjygxQT8tDesigned and operated a simulated enterprise environment to run repeatable attack and detection scenarios and improve incident response workflows.
Built and operated a hands-on cyber range lab environment that simulates real-world enterprise attack and detection scenarios across Active Directory and cloud-integrated systems. The project focused on operational reliability, incident response readiness, and monitoring validation.
I designed the network layout, deployed virtual machines, configured logging and alert pipelines, and created repeatable attack scenarios to test detection quality and response procedures. I developed operational runbooks and reset procedures so scenarios could be executed consistently and safely.
The lab was used to validate alert behavior, practice incident triage, test containment steps, and improve root-cause analysis workflows. This project strengthened operational discipline, troubleshooting methodology, and incident-handling structure, similar to those in production support environments.
