• At least 1+ year hands-on experience with security alert triage through work, an internship, or a practical lab, including use of at least one SIEM and exposure to EDR or XDR and case-management workflows

• Basic use of indicators of compromise, reputation sources, and threat-intelligence context, with awareness of the MITRE ATT&CK framework
• Ability to create a concise investigation timeline and document evidence, actions, conclusions, and handover or escalation notes in a case-management system
