From security signals
to actionable insight.

A Cybersecurity Officer with hands-on experience in security operations, vulnerability remediation, and enterprise infrastructure security. I review vulnerability assessment findings across servers and network devices, evaluate affected services and operational risks, and collaborate with Security Operations Center (SOC) teams and infrastructure engineers to prioritize and implement remediation measures. My responsibilities include server security assessments, service updates, security hardening, patch management, and minimizing the attack surface of network services.

My experience in Security Operations Center (SOC) environments includes security monitoring, alert triage, log analysis, incident investigation, SIEM dashboard configuration, custom decoder development, and correlation rule creation. I also review security configurations for management controllers and surveillance systems, assess the operational impact of security changes, and verify the continued availability of critical services following updates.

Beyond vulnerability remediation, I document security findings and recommendations, evaluate cybersecurity solutions against business and technical requirements, and contribute to feasibility studies and procurement specifications.
