Role Expectations: Monitor, investigate, and respond to security alerts across cloud, endpoint, identity, email, SaaS, and enterprise environments. Take ownership of assigned incidents from triage through containment, remediation support, documentation, and lessons learned. Work with internal teams and external SOC partners to ensure incidents are handled consistently and within defined operational expectations. Contribute to detection improvements, playbook maturity, operational documentation, and knowledge sharing across the SOC team. Key Responsibilities: 1. AWS Security Incident Response & Cloud Security Investigate AWS security alerts, suspicious activity, misconfigurations, and potential compromise scenarios using available cloud logs and security tooling.
