Document alert triage findings accurately and completely in the ITSM or case management platform, ensuring all relevant event data, analysis steps, and disposition rationale are captured for audit and investigation purposes.
Escalate confirmed or suspected security incidents, high-priority alerts, and complex analytical findings to senior engineers and incident response personnel in a timely and well-documented manner.
Assist with security event correlation and timeline reconstruction activities, aggregating and analyzing event data across multiple log sources to support incident investigation and root cause analysis efforts.
Support the development and maintenance of alert triage procedures, runbooks, and analysis playbooks, contributing documentation based on recurring alert scenarios and lessons learned from completed triage activities.

Threat Intelligence Integration

Assist with the integration and operationalization of threat intelligence feeds within the SIEM platform, supporting the configuration of indicator of compromise (IOC) matching rules, threat intelligence enrichment workflows, and automated alert enrichment capabilities.
