Logical Policy Diagrams: Used SIEM tools to design CIIs logical policy diagrams and monitor inbound, outbound, and internal network traffic to detect unusual activity and unauthorized port usage. True positive and SOC alerts: Analysed SOC and True-Positive alerts for all CIIs under West Zone NCIIPC on daily, weekly, and quarterly cycles. Validated alerts using logs and threat intelligence, classified them as TP/FP/Benign, and investigated IOCs (IP, hash, domain) to identify attack patterns. National Cyber Coordination Centre (NCCC) & Vulnerability Assessment (VA) report: Managed alerts & reports for West Zone CIIs by analyzing, prioritizing, correlating, escalating incidents, tracking ATRs, verifying remediation, and ensuring compliance with NCIIPC, reporting, and secure record management.
