Information Security Analyst at L & A Technologies LLC, triaging 50+ weekly QRadar alerts and supporting incident response.

Message

At L & A Technologies LLC, I monitor enterprise networks, endpoints, and applications through IBM QRadar, triaging 50+ weekly security alerts and escalating validated incidents. I analyze firewall activity, endpoint logs, system events, and network traffic to distinguish true incidents from false positives.

I also conduct vulnerability assessments and penetration testing, documenting exploitable findings and coordinating remediation. I support incident response across containment, eradication, and recovery, and help update security policies aligned with ISO 27001 and NIST CSF.

Previously, I worked in risk, compliance, governance, and IT audit roles at COJENE, KPMG, and Crowe. My work included third-party risk reviews, ITGC testing, and cloud and AI governance considerations; I hold an MSc in Information Security and certifications including ISC2 CC, CCNA, Azure Fundamentals, and Azure AI Fundamentals.
