• Create and update tickets with accurate details, evidence, and recommended next steps.
• Follow runbooks, SOPs, and escalate incidents to L2/OT teams when necessary.

L2 – Tier-2 (Second Line)

• Perform detailed investigations, RCA, and incident validation.
• Coordinate with OT engineers, SMEs, and asset owners to drive remediation activities such as configuration changes, segmentation updates, and firmware updates.
• Tune detection rules, reduce false positives, and improve baseline models.
• Maintain and enhance playbooks, runbooks, and detection signatures.
• Conduct advanced packet analysis and reconstruct sessions using pcaps.
• Correlate Claroty telemetry with SIEM, NMS, and other monitoring systems.
• Manage asset inventory, reconciliation, anomaly detection tuning, and forensic data collection.

Minimum Experience and BackgroundL1 Requirements
