10. Participate in post-incident reviews, contributing to process and detection improvements.

Responsibilities: 

1. Monitor alerts generated from the SOC/SIEM and perform initial to intermediate-level investigations.
2. Review and validate security events from multiple log sources and identify legitimate threats.
3. Perform deep-dive investigations for incidents involving malware, phishing, insider threats, and cloud breaches.
4. Assist in detection rule creation and tuning under the guidance of senior incident responders.
5. Use frameworks like MITRE ATT&CK for mapping and improving detection quality.
6. Conduct threat hunting using Elastic Stack and related tools.
