Focus

Blue-team analysis
Defense is the focus: hardening systems, reading logs, and understanding attacks from the analyst's side. That direction comes out of the NEISD iCSI Cybersecurity Program and CyberPatriot, backed by the CompTIA CySA+ certification.

CTF competition
I compete in events like National Cyber League, BYU CTF, RowdyCon, CTF@CIT, and Squ1rrel CTF. CTFs are where fundamentals get pressure-tested against real challenges, and writeups are published here as they're finished.

Tools & homelab
Practical tooling matters: this site ships small browser-based security utilities, and a homelab gives me a safe place for hands-on experiments. Notes from that work are collected as lab notes.
