  • Cross‑Source Correlation: Stitching together fragmented data from SIEM, EDR, and NDR tools to build a comprehensive picture of the attack.
• Proactive Threat Hunting and Detection Engineering

• Mentorship and Leadership
  • Guidance for other members of the team: In the future, mentoring and training Tier 1 and Tier 2 analysts on complex investigations and new technologies.
  • Quality Assurance: Performing ticket reviews and providing feedback to ensure high‑quality documentation and adherence to Service Level Agreements (SLAs).
• Strategy, Compliance, and Reporting
  • Vulnerability Assessment: Analyzing vulnerability scan results to identify critical weaknesses and recommending remediation plans.
  • Reporting and Compliance: Generating reports on incidents, trends, and SOC performance for management, and auditing systems for compliance (e.g., ISO 27K1, PCI DSS, HIPAA).
  • Threat Intelligence Integration: Incorporating external threat intel feeds to anticipate emerging threats and update defenses.
