Monitored and responded to security incidents in a 24×7 SOC setup, ensuring timely triage and resolution across 18+ enterprise sites. Investigated alerts across EDR, firewall, and SIEM inputs — documented findings, escalated critical cases, and drove incident closure. Worked with Azure Sentinel (familiar) for rule-based alerting and log visibility; enriched IOC context using threat feeds. Performed packet-level analysis (Wireshark) for root cause investigation of DDoS symptoms and internal traffic anomalies. Applied knowledge of WAF behavior and rule sets while reviewing access control gaps and web-layer alerts. Conducted basic threat hunting activities, using TTP patterns to correlate suspicious behavior with known attack campaigns. Created and maintained SOPs and incident response playbooks for shift teams; contributed to RCA documentation. Collaborated with network and firewall teams on ACL issues, policy tuning, and segmentation reviews.
