Position Responsibilities

Vulnerability Analysis and Remediation

• Review vulnerability scan results and security configuration findings to determine affected assets, exposure, and required corrective actions.
• Prioritize assigned findings using exploitability, asset criticality, external exposure, threat activity, and established remediation requirements.
• Validate findings, investigate potential false positives, and identify asset owners responsible for corrective action.
• Create and maintain remediation tickets with clear technical details, recommended actions, ownership, and due dates.
• Coordinate patching, configuration changes, software upgrades, and removal of unsupported technologies with infrastructure, endpoint, network, and application teams.

• Verify remediation through rescanning, configuration review, or other technical evidence before closing findings.
• Track overdue vulnerabilities, document remediation barriers, and elevate unresolved exposures.
• Support assessment of newly disclosed and actively exploited vulnerabilities to identify affected systems and accelerate remediation.
• Document compensating controls and exception requests for review by the appropriate risk owner.

Security Incident Ticket Support

• Triage and investigate assigned security tickets involving suspicious emails, endpoint alerts, potentially compromised accounts, unauthorized software, and other security concerns.
