Data Governance Lab — Purview
Taxonomy, LFPDPPP glossary and 4 PII classification rules over ~1,350 records; remediation memo mapped to LFPDPPP Arts. 3, 15–18 & 37.
Cybersecurity student at Tec de Monterrey — I turn security controls, data governance and risk into clear, defensible compliance.
ScrollI'm Alfonso — a cybersecurity student who fell for the unglamorous half of security: governance, risk, and the rules that decide whether a control actually counts. I learn by building (a data-governance lab in Purview, a SIEM on AWS) and by competing, which is how I landed top-5% in Latin America's biggest cyber contest. What drives me is making risk legible — turning messy systems into something a business can trust, and writing it down so it holds up.
Microsoft Purview, LFPDPPP & GDPR — taxonomy, regulatory glossaries, PII classification (CURP, RFC, CLABE), consent & retention.
GRC risk — likelihood × impact analysis, risk registers and treatment plans that turn scattered findings into decisions a business can act on.
Wazuh & AWS SIEM — insider-risk alerts, audit logs for traceability, and triage with chain of custody.
ISO 27001 & GRC fundamentals — mapping technical controls back to the regulation that justifies them.
AWS with Infrastructure-as-Code (CDK) — serverless detection pipelines and least-privilege by default.
VLAN segmentation, pfSense / OPNsense firewalls and encrypted site-to-site tunnels across multi-branch networks.
CTF exploitation, enumeration and privilege escalation — understanding the attacker to defend the control.
Leading a university security club — talks on threat analysis, malware and data-protection culture.
Skills — by the focus I put into each
Tec de Monterrey (ITESM)
Lead talks and initiatives on threat analysis, malware and data protection — building a security culture across the student community.
Microsoft Purview · simulated Mexican fintech
Built a governance lab: collection taxonomy, an LFPDPPP-aligned glossary and PII classification (CURP, RFC, CLABE, email). Scanned ~1,350 records and flagged 20% of clients with no documented consent, plus expired vendor contracts and a missing retention policy.
AWS · compliance monitoring & insider risk
Deployed a serverless SIEM (CDK → Kinesis → S3 → Lambda → OpenSearch) detecting after-hours access, bulk transfers and exfiltration, with audit logs for traceability. ~700 events/day across 5 endpoints; one incident taken through full triage and a formal findings report.
DDD Impressions · 3 branches, 52 employees
Designed a segmented corporate network (VLANs, Inter-VLAN routing), hardened the perimeter with pfSense/OPNsense and encrypted tunnels between CDMX, Monterrey and Mérida, applying VLSM with a 25% scalability margin. Delivered at $26,371 USD.
OAS · cybersecurity competition (Latin America)
Evaluated security controls in simulated environments using OWASP, documenting findings with impact, probability and remediation. Analyzed access-control & credential-management gaps and produced severity-classified reports. Ranked 45th of 845.
Taxonomy, LFPDPPP glossary and 4 PII classification rules over ~1,350 records; remediation memo mapped to LFPDPPP Arts. 3, 15–18 & 37.
Serverless SIEM (CDK, Kinesis→S3→Lambda→OpenSearch) for compliance monitoring & insider-risk detection, with full incident triage and audit logs.
VLAN-segmented network with pfSense firewalls and encrypted tunnels across CDMX, Monterrey & Mérida; VLSM with 25% growth margin. Delivered at $26K.
Control evaluation in simulated environments with OWASP; impact/probability scoring and severity-classified vulnerability reports.
End-to-end ops dashboard (Python → PostgreSQL → Power BI) tracking SLAs, incidents and retention for Borregos Gaming, with auto-filled postmortems.
