Which of the following best describes a Tier 3 SOC Analyst?

A Tier 3 SOC Analyst is a senior security expert with deep knowledge of cybersecurity threats and incident response. Their primary responsibilities include handling the most complex and severe security incidents escalated from Tier 1 and Tier 2. They perform advanced forensic analysis, malware reverse engineering, and lead proactive threat hunting initiatives to uncover hidden threats within the network. Their expertise is crucial for resolving major security events and improving the organization's overall security posture.

A security expert responsible for initial triage of alerts: This is the primary role of a Tier 1 analyst, who performs initial investigation and escalates true positives. A junior analyst responsible for managing firewall configurations: This is typically a network security administrator role, not a senior SOC analyst function focused on threat hunting. A helpdesk technician assisting with password resets: This is an IT support function, entirely separate from the specialized roles within a SOC.
