Hi there, I'm Daniel!

Security Analyst Threat Hunter Researcher

Welcome to my digital headquarters. This profile documents my journey into the Art of Investigation, combining technical analysis with probabilistic thinking to solve security challenges.


🚀 The Ecosystem

My work is divided into two primary repositories. Click the badges below to navigate:

🛡️ The Portfolio

Cybersecurity Repo

  • Focus: Deep-dive investigations, fully documented projects, and end-to-end analysis.
  • Key Phases: Foundations | Threat Intelligence | AI & Automation

⚡ The Lab

Daily Drill Repo

  • Focus: Continuous learning, quick scripts, and "Art of Investigation" notes.
  • Key Contents: Linux Admin | SOC Playbooks | Lab Notes

🛠️ Tools & Technologies

I build and analyze using a "Code-First" approach to security.

Category Stack
SIEM & Analysis Splunk Wireshark
Operating Systems Linux Windows
Automation & Data Python Pandas Jupyter Bash
Infrastructure VMware Ubuntu

🧠 Philosophy & Methodology

My approach to cybersecurity is built on:

  1. Probabilistic Thinking: Applying Bayes' theorem and logic to triage alerts and reduce false positives.
  2. The Art of Investigation: Moving beyond tools to understand the intent and narrative of an attack.
  3. Documentation: Believing that if it isn't documented, it didn't happen.

🖥️ Current Lab Infrastructure

My projects are built and tested in a dedicated home lab environment:

  • Hardware: Dell AIO Server
  • Virtualization: VMware ESXi
  • Visualization: JupyterLabs (integrated with GitHub for reporting)
