01 About

Detection-first, hands-on defence.

MSc Computing graduate (Sheffield Hallam University, 2026 — Secure Distributed Systems & Multi-Cloud Architecture) and B.Tech Electronics & Communication Engineering graduate, with hands-on experience across SOC monitoring, threat detection, incident triage, IT support, and cloud security.

Every project in this portfolio is a working tool that solves a real SOC problem — built from the ground up and fully documented. Not demos: the same lookups, correlations, and reports an analyst runs on the job, automated end to end.

Background spans a Cyber Security Engineer rotation at Redynox, security-tooling internships at CodeAlpha and Future Interns, and a full-time SOC role at Emandi Exim — plus real operational leadership from a floor-lead role in Sheffield.

Based in Sheffield on a UK Graduate visa with full work authorisation, and available to start immediately.

// Areas of focus

SOC/IRIncident response — SIEM-style log analysis, alert triage, detection → investigation → escalation
THREATThreat detection — MITRE ATT&CK mapping, IOC correlation, campaign & behavioural analysis
INTELThreat intelligence — OSINT automation, IP/domain investigation, cert transparency
CLOUDCloud security — IAM/RBAC, Zero Trust, posture monitoring across AWS, Azure, GCP
OFFSECOffensive-informed defence — OWASP Top 10, API security, vuln assessment, Suricata IDS/IPS
02 Security Engineering Portfolio

Tools a SOC analyst would use on the job.

All fully working, tested, and documented on GitHub. Built from scratch — no boilerplate, no demos.

🛡️ Mini-SOC-in-a-Box
100% recall/precision

A from-scratch SOC detection pipeline. Detects a full kill-chain intrusion using detection-as-code (YAML → Sigma), maps every alert to MITRE ATT&CK, and correlates them into a single incident — measured at 100% recall and precision with zero false positives.

  • Detection-as-code — rules written in YAML, compiled to Sigma, version-controlled and tested
  • Full kill-chain detection — every alert mapped to a specific MITRE ATT&CK technique
  • Incident correlation — related alerts grouped into one coherent incident with pytest coverage
PythonSigmaMITRE ATT&CKpytest
github.com/Singh847/mini-soc
🕵️ OSINT Investigator v2
50 IOCs / batch

Automated open-source intelligence for SOC analysts. Enter any IP, domain, or URL and get a complete investigation report in one click — the same lookups an analyst runs manually in 10–15 minutes, done in seconds.

  • MITRE ATT&CK auto-tagging — every finding mapped to a specific technique with a plain-English reason
  • Campaign correlation engine — clusters related IOCs by shared ASN, registrar, nameserver, or registration week
  • Ticket-ready PDF reports with risk indicators and recommendations

📊 Log Sentinel v3
9 patterns

Mini-SIEM that parses SSH auth, web access, and Windows Security Event logs — detecting 9 attack patterns, every alert mapped to MITRE ATT&CK.

  • Correlation engine — chains alerts into incidents like "brute force → lockout → admin privileges = full domain compromise"
  • GeoIP enrichment + environment risk score (0–100)
  • Real-time watch mode tails live logs and fires alerts as attacks happen

🧠 Phishing URL Detector
93.5% acc

ML classifier that detects phishing URLs from URL text alone — no network calls, instant offline predictions. Trained on 2,072 labelled URLs.

  • 24 lexical features — abused-TLD detection, punycode lookalikes, IP-as-hostname, subdomain depth
  • Flask web UI + JSON API for integration with other tools

🔑 Password Audit — SOC Tool
HIBP k-anon

SOC-grade credential tool for post-incident vault auditing — check dumped hashes against HIBP without ever sending the full hash.

  • Cross-vault pattern detection — finds template reuse, base-word reuse, keyboard walks
  • PDF executive health report with pattern risk score; imports Bitwarden / Chrome / 1Password / LastPass

☁️ Multi-Cloud Control Plane
MSc research

Cloud security posture monitoring that scores AWS, Azure, and GCP on latency, cost, availability, and security — with misconfiguration and drift detection, severity classification, and automated PDF reporting.

🔐 Asset Security API
3-tier RBAC

REST API implementing JWT authentication, token blacklisting, three-tier RBAC (admin / operator / viewer), and full audit logging — core IAM and least-privilege principles applied end to end.
