πŸ‘‹ Hello, I'm Rosa!

Aspiring System Administrator | Security Operations Enthusiast

I’m an IT student passionate about enterprise infrastructure and security hardening. I focus on building resilient systems, automating administrative tasks, and understanding the β€œwhy” behind network vulnerabilities. I’m exploring cybersecurity roles where I can leverage infrastructure expertise like IAM, SOC analysis, and cloud security.


πŸ› οΈ Current Technical Focus (2026)

  • Active Directory: Building forest/domain structures, GPO hardening, and identity management.
  • Security Research: Traffic analysis with Wireshark and threat modeling in virtualized environments.
  • Automation: Leveraging PowerShell and Bash to streamline repetitive SysAdmin tasks.

πŸ“‚ Featured Security Labs

Deployment of a Windows Server 2025 environment featuring automated user onboarding and GPO-based hardening.

  • Tools: VMware, Windows Server, PowerShell, Group Policy.
  • Key Achievements: Successfully promoted a DC in a new forest (homelab.local) and designed a logical OU hierarchy (UAE_Assets) to streamline administrative delegation, and implementing restricted groups via GPO.

A collection of packet captures and analysis reports focusing on identifying suspicious network behavior.

  • Tools: Wireshark, TShark, Nmap.
  • Key Outcome: Identified anomalous DNS and HTTP traffic patterns to simulate real-world threat detection.
