MSc Project

AI-Powered Endpoint Security & Automated Incident Response

Feb 2026 – Apr 2026
Wazuh XDR n8n LangChain Python Wireshark MITRE ATT&CK
  • Built a full SOC monitoring pipeline using Wazuh XDR for real-time endpoint and web threat detection
  • Mapped detections to MITRE ATT&CK techniques T1110 (Brute Force) and T1078 (Valid Accounts)
  • Automated alert triage and incident response with n8n and Python, enabling firewall-based IP blocking and host isolation via Wazuh Active Response
  • Integrated LangChain (LLM) for AI-powered incident summarization and OSINT enrichment, reducing analyst triage time
  • Developed a daily automated reporting system generating severity-classified HTML and JSON security reports
Personal Lab

AWASA — Automated Web Application Security Assessment

Feb 2026 – Apr 2026
Python LangChain Claude AI Gemini API OWASP Top 10
  • Designed an AI-powered web security scanner automating reconnaissance and vulnerability detection
  • Implemented 10+ security checks mapped to OWASP Top 10 2021 categories with automated report generation
  • Integrated Claude/Gemini LLM via LangChain for intelligent vulnerability analysis and false positive filtering
  • Severity classification system: Critical / High / Medium / Low
  • Reduced manual assessment time with end-to-end automated scanning and AI-driven remediation recommendations
Controlled Lab
