Hi, I'm Sreejith Reji 👋

Cybersecurity Professional | MSc Cyber Security | CEH | Security+

I hold a Masters in Cyber Security with industry certifications, and I am currently building hands-on Python scripting, SQL, KQL and SPL skills applied directly to real SOC workflows — log analysis, threat detection, IOC enrichment, and security automation.

🎯 Current Focus

  • 🐍 Python — log parsing, automation, API integration, IOC enrichment
  • 🔍 KQL — Microsoft Sentinel and Defender XDR threat hunting
  • 🔎 SPL — Splunk alert investigation and detection engineering
  • 🗄️ SQL — querying security data and SIEM exports
  • 🪟 Windows Security — Event Log analysis, Active Directory fundamentals
  • 🔵 SOC workflows — alert triage, incident investigation, shift reporting

🛠️ Projects

Project Status Description
soc-python-tools 🔨 In progress Python scripts for SOC automation — IOC checker, log analyser, alert triage
soc-sample-logs ✅ Live 500-line realistic SOC log files simulating a full attack lifecycle
kql-soc-queries ✅ Live Comprehensive KQL query library for Microsoft Sentinel and Defender XDR
spl-soc-queries ✅ Live Comprehensive SPL query library for Splunk SOC analysts
cybersecurity-portfolio ✅ Live Full portfolio — tools, skills, and learning roadmap
SQL Security Investigation Lab 📋 Planned SQL queries for security data analysis
Windows Event Log Notes 📋 Planned Reference notes for Windows security event IDs
