🧑‍💻 About Me

I'm a Computer Science student (4/8) based in Brazil, building hands-on skills in cybersecurity, SOC operations, and infrastructure monitoring.

My focus is on the defensive side of security — detecting real attacks, analyzing network traffic, and building functional lab environments that mirror production SOC workflows.

  • 🎓 B.Sc. Computer Science — currently in 4th semester
  • 🛡️ Focus areas: SOC Operations · Threat Detection · Incident Response · Log Analysis
  • 🔬 Currently building: homelab environments with Elastic Stack, Zeek, and attack simulations
  • 📚 Also studying: Data Structures, Databases, JavaScript, C
  • 🌱 Learning on the side: English · Basketball

🔐 Featured Project — Threat Detection Lab

A functional SOC environment running on a single VM with only 3.2 GB RAM.

Repo Status Elastic Stack Zeek

Network Sentinel Lab simulates and detects real attack techniques in a controlled environment:

Layer Stack
SIEM / Logging Elasticsearch · Kibana · Filebeat
IDS / NTA Zeek 6.0
Vulnerable target Apache2 + PHP · MySQL
Infrastructure Ubuntu Server 22.04 · VirtualBox
Automation Bash scripting

Attack scenarios covered (MITRE ATT&CK):

  • T1595 — Active Scanning via Nmap → detected by Zeek conn.log
  • T1190 — SQL Injection against vulnerable web app → logged in attacks.log
  • T1110 — Brute-force via Hydra → captured in login_attempts.log
  • T1046 — Network Service Discovery → flagged by Zeek

OWASP Top 10 vulnerabilities intentionally implemented for detection practice (A01, A03, A04, A05, A06:2021).
