About Me

I am a Cyber Security Infrastructure and Detection Engineer with hands-on experience across SOC operations, detection engineering, incident response, and secure infrastructure design. My background combines strong infrastructure fundamentals with advanced defensive security, allowing me to build controls that work reliably in real operational environments.

I design and operate SIEM-based detections using Microsoft Sentinel (KQL) and Splunk (SPL), working closely with SOC teams to investigate incidents, tune alerts, reduce false positives, and improve detection quality — all aligned to MITRE ATT&CK, covering identity abuse, MFA fatigue, PowerShell misuse, ransomware indicators, and lateral movement.

From an infrastructure perspective I bring practical knowledge of TCP/IP, DNS, DHCP, VLANs, firewalls, VPNs, and traffic analysis using Wireshark. I have designed DNS security monitoring pipelines including DNSSEC-enabled recursive resolution, secure log forwarding, and SIEM-based detection of malicious domains.

My early career included NOC and data centre operations, network rack builds, device configuration, and enterprise server migration support — giving me the infrastructure depth that most detection engineers lack. I am seeking a role where I can contribute immediately to security operations while continuing to grow as a detection-focused security engineer.

Key Projects

🔍
Microsoft Sentinel Threat Hunting Portfolio
Sentinel · KQL · Sysmon · MITRE ATT&CK
  • Built a Threat Hunting Workbook with 20+ custom KQL queries detecting PowerShell abuse, C2 traffic & lateral movement.
  • Analysed BEC attack paths — detections for MFA fatigue, inbox rules & token replay.
  • Developed ransomware early-detection workflows focusing on behavioural patterns & file system anomalies.
  • Engineered credential theft detections for LSASS dumping & Kerberoasting (Event Logs 4624/4625).

Cyber-Physical SOC: IoT to Splunk Pipeline
Splunk · SPL · Python · Raspberry Pi · DHT11 / PIR / MPU6050
  • Designed end-to-end telemetry pipeline: Sensors → Raspberry Pi → JSON logs → Splunk Universal Forwarder.
  • Integrated DHT11 (temp/humidity), PIR (motion), and MPU6050 (vibration/tamper) sensors.
  • Built SPL-based time-window correlation logic (Motion + Tamper within 120s) to reduce false positives.
  • Automated incident creation with severity scoring and SOC-style lifecycle tracking.

Cowrie Honeypot & SIEM Detection Engineering
Splunk · Cowrie SSH · MITRE ATT&CK · IR Playbooks
  • Deployed Cowrie SSH honeypot on Raspberry Pi — capturing auth attempts, HASSH fingerprints, command execution & session lifecycle.
  • Forwarded structured JSON telemetry to Splunk via Universal Forwarder.
  • Built SOC detections for brute-force (T1110), credential compromise (T1078), and post-exploitation (T1059, T1105).
  • Created IR playbooks for high-severity events; honeypot kept off public internet per DMZ best practice.

DNS Security Monitoring Platform
Pi-hole · Unbound · DNSSEC · Splunk · Tailscale
  • Built a SOC-grade DNS telemetry platform treating DNS as a primary security signal.
  • Pi-hole for filtering + Unbound for full recursive DNSSEC resolution; all activity forwarded to Splunk.
  • Secured transport over a private Tailscale mesh network; host hardened with firewall rules & access controls.
  • Enables detection of DNS tunnelling, beaconing, and malicious domain patterns. MITRE ATT&CK extension planned.

"Amanpreet never allowed challenges to break his focus. He was the one who stayed consistent, encouraged others, shared notes, explained concepts patiently, and supported anyone who was falling behind. What I admire most is how he handles pressure — calmly, logically, and with a maturity far beyond his age. Amanpreet is not just hardworking; he is reliable, humble, and genuinely supportive. Anyone who works with him will see the same qualities: resilience, integrity, and a mindset that refuses to give up."
