Hey, I'm Ersin. πŸ‘‹

Career changer. 3 CompTIA exams in 5 months. Building toward SOC Operations.

I don't just study for certifications β€” I build labs, break things, and document what I find.

CompTIA A+ CompTIA Security+ CompTIA Network+ TryHackMe


🎯 Where I'm headed

I'm building a career in Security Operations β€” learning how attacks work in order to detect, analyze, and respond to them effectively.

My goal: a SOC Analyst role where I contribute to threat detection, alert triage, and incident response. I believe the best defenders understand how systems can be broken β€” so I build labs that reflect real attack scenarios and document every finding.


πŸ”’ Certifications

Certification Status Date
CompTIA A+ βœ… Passed Jan 2026
CompTIA Security+ βœ… Passed Mar 2026
CompTIA Network+ πŸ”„ Studying 2026

πŸ§ͺ What I'm building

I learn by doing. My HomeLab Projects and HomeLab Aegis repos document real hands-on work β€” not tutorial copy-paste, but actual discovery, mistakes, and lessons. Aegis goes deeper: IDS deployment, SIEM integration, exploitation and detection.

πŸ–₯️ Lab Environment

Machine Specs OS Role
πŸ’» MacBook Pro 16GB RAM Β· 500GB SSD macOS Primary workstation β€” scanning, documentation, analysis

03 Exploitation & Detection If Metasploit gets a shell β€” does the IDS see it? πŸ”œ
04 Lateral Movement Can SIEM detect movement between hosts post-compromise? πŸ”œ
05 PCAP Forensics What does C2 and infostealer traffic look like in a PCAP? πŸ”œ
06 Detection Rule Writing Can we write a Suricata rule that catches a specific threat? πŸ”œ
07 Incident Response Can we build a full IR timeline and harden the environment? πŸ”œ

🧠 How I think

A certification proves you studied. A lab proves you understand.
I do both.

  • πŸ” I question results before accepting them
  • πŸ“ I document findings, not assumptions
  • ⚑ I treat every lab as a real environment
  • πŸ” I revisit and improve β€” no lab is ever truly finished

πŸ“Œ Currently

πŸ“– Studying CompTIA Network+ while building hands-on security labs πŸ§ͺ Running firewall and traffic analysis labs β€” documenting everything πŸŽ“ Cybersecurity Weiterbildung in Germany β€” finishing late 2026 πŸ’» TryHackMe Cybersecurity 101 β€” 51% complete
