Incident Response/Threat Hunting/Cloud & SOC Security

MSc Information & Network Security student building hands-on detection and response capability through a home SOC lab, MITRE ATT&CK-mapped anomaly research, and applied cloud security work — aimed at defending enterprise and product environments against real-world threats.

01

Detections — Projects & Applied Work

Logged as detections, because that's how a SOC would triage them: each one flags a real capability, with the tooling and technique behind it.

DET-002High confidence

Authentication Anomaly Detection & Risk Scoring Engine

MSc dissertation project: a Python risk-scoring engine using Isolation Forest and LSTM models to flag anomalous login behaviour — normal, suspicious, and brute-force scenarios — with detections mapped to MITRE ATT&CK tactics and techniques. Supervised by Dr. Eckhard Pfluegel, in collaboration with industry partner David Douglas.

Home SOC & SIEM Lab

Self-built lab for SOC analyst portfolio work: Windows Server 2022 and endpoint telemetry via Sysmon (SwiftOnSecurity config), ingested into Splunk Enterprise for log analysis, detection engineering, and incident triage practice.

AI-Powered Vulnerability Scanner

Modular Python tool built for postgraduate coursework: scanning, CVE lookup, an LLM-based triage agent (Groq / LLaMA 3.3 70B), and automated reporting — tested against live scan targets, with full architecture documentation and a risk register.

ISO 27001 ISMS Gap Assessment

GRC internship deliverable: asset register, ISO 27001 gap assessment, and security policy documentation built around a simulated FinTech environment — grounding technical detection work in governance and compliance context.
