• Playbook Development and Refinement: Create, maintain, and enhance Incident Response (IR) playbooks and procedures, integrating automation.
• DFIR and Post-Incident Analysis: Lead detailed forensic investigations to determine the root cause (Root Cause Analysis - RCA) and scope of compromise, facilitating meetings and preparing post-mortem documentation.
• Threat Detection: Advanced knowledge of threat detection, rule creation, and rule tuning/enhancement in SIEM and EDR.
• Cyber Threat Intelligence (CTI): In-depth mastery of the full CTI lifecycle, focusing on converting data into actionable intelligence to strengthen SOC routines.
• Vendor Management (Tier 1/Tier 2): Work in direct partnership with Tier 1 to optimize operational routines, maximizing value delivery from the active contract and vendor.
