What I'm looking for

I’m seeking an entry-level SOC Analyst role to contribute to alert monitoring, triage, and incident documentation. I want to strengthen detection with SIEM workflows while learning from real incidents in a Blue Team environment.

I’m a Cybersecurity Analyst Jr focused on SOC / Blue Team operations, (ISC)² Certified in Cybersecurity (CC), and hands-on in SIEM deployment (Wazuh), endpoint monitoring, and Linux hardening. I implemented custom File Integrity Monitoring rules and analyzed authentication logs for brute-force detection, strengthening alerting with evidence-based documentation.

Through my projects, I deployed Wazuh (Manager, Indexer, Dashboard), validated SSH brute-force alerts and PAM/sudo activity, and produced technical hardening findings using Lynis. I also secured EC2 deployments on AWS by enforcing least-privilege access and verified SSH connectivity with .pem key authentication—now looking to contribute to SOC alert monitoring, triage, and incident documentation.
