Monitored ELK/Wazuh SIEM dashboards for phishing, brute-force, botnet, malware, suspicious login, endpoint, and network-based alerts across 20+ simulated systems. Investigated security events by reviewing authentication logs, endpoint activity, firewall logs, network traffic indicators, network device logs, and alert context to identify IOCs, validate severity, reduce false positives, and prepare escalation notes. Followed SOC playbooks to document findings, recommend containment/remediation actions, maintain incident records, prepare shift handover notes, and support 24x7-style security monitoring workflows.
