🧭 Background

➜ ➜ ➜ ➜ ➜
Three years on the HPE-Aruba TAC team gave me a ground-level view of how enterprise infrastructure actually behaves under attack conditions — real customers, real incidents, real production networks. The security thread was always there: VAPT cycles, access control hardening, Splunk log analysis, flagging misconfigurations before they became incidents. That operational foundation is what pushed me toward formalizing the security side at GMU.

💡 My logic: understand how everything connects, then learn how to defend it.
