root@fathur:~$ Saya adalah seorang siswa di SMK Bangun Nusa Bangsa yang memiliki antusiasme mendalam terhadap arsitektur jaringan komputer dan keamanan sistem informasi.

Perjalanan saya dimulai dari merancang topologi jaringan lokal, mengonfigurasi perangkat router/switch (Cisco & MikroTik), hingga mendalami dunia Offensive & Defensive Security. Saya terbiasa melakukan simulasi penetration testing di lab terkontrol untuk mengidentifikasi kerentanan sebelum dieksploitasi oleh pihak yang tidak bertanggung jawab.

Dengan kemampuan administrasi Linux Server dan otomatisasi script (Bash/Python), saya fokus membangun infrastruktur yang tangguh, efisien, dan memiliki sistem pertahanan berlapis (defense-in-depth).

Network Architecture & Routing
Konfigurasi VLAN, OSPF, BGP, NAT, Hotspot, VPN Tunneling (WireGuard/OpenVPN) pada Cisco IOS dan MikroTik RouterOS.
Vulnerability Assessment & PenTesting
Reconnaissance, network mapping, scanning kerentanan web & network, privilege escalation, dan analisis paket via Wireshark.
Linux Sysadmin & Hardening
Manajemen server Debian/Ubuntu/Arch Linux, implementasi Firewall IPTables/UFW, fail2ban, SSH hardening, dan container Docker.
