IT Support & Security Analyst · SIEM · Alert Triage · Security Automation

Help Desk Analyst at Upstate Medical University, supporting clinical and administrative staff in an SLA-driven healthcare environment. Outside the queue, I build hands-on security labs in Azure: Microsoft Sentinel detections in KQL, honeypots that catch real attackers, and SOAR playbooks that enrich and contain threats in seconds.

Security Projects

Detection & Response

SOC Home Lab: Azure Honeypots + Sentinel

Three internet-facing honeypots feeding Microsoft Sentinel, used to write and test real detections against real attackers.

  • Deployed Windows RDP, Cowrie SSH and Endlessh honeypots with Azure Monitor Agent and custom log tables; captured 1.24M attempts from 75 IPs with zero compromises.
  • Wrote 5 KQL analytics rules (password spray, brute-force-then-success) and rebuilt the low-and-slow rule after v1 missed an attacker guessing once every 12 minutes.
  • Reconstructed an SSH intrusion chain, mapped 13 ATT&CK techniques, and identified Panchan, Mirai and Bashlite samples by hash.

SOAR Automation

Sentinel SOAR: Automated Brute-Force Response

A Logic App playbook that enriches Sentinel incidents with threat intel and blocks high-risk IPs automatically.

  • Integrated Sentinel, the AbuseIPDB API and the Azure REST API, running under a least-privilege managed identity.
  • Cut triage to ~12 seconds (8–18 s) from 10–15 minutes; blocked IPs made zero further attempts.
  • Per-IP grouping reduced 65 alerts to 6 incidents, about 91% less noise for analysts.

Data Analysis

HHS Healthcare Breach Analysis

An analysis of every breach reported to HHS OCR, turned into practical guidance for a small clinic.

  • Cleaned and analyzed 8,013 breach records (2009–2026) with Python and pandas.
  • Showed hacking grew to 81% of breaches by 2025; published an interactive Plotly dashboard.
  • Wrote a security-budget memo for a 40-person clinic based on the findings.

Infrastructure as Code

This Website: Azure + Terraform

The page you're reading is hosted on Azure Storage and deployed entirely with Terraform.

  • Storage account hardened with TLS 1.2+, HTTPS only, no anonymous blob access and soft delete.
  • GitHub Actions runs fmt, validate and a Checkov security scan on every push, and fails on any unaddressed finding.
  • Each accepted risk is documented in code with a written justification.
