• Apply vulnerability scoring and prioritization methodologies, including CVSS, CISA Known Exploited Vulnerabilities (KEV), vendor advisories, and threat intelligence, to support risk-based remediation decisions.
• Assess vulnerabilities and security configurations on Linux systems, including troubleshooting authenticated scans and supporting remediation activities.
• Support compliance and security assessment activities involving STIGs, DoD security requirements, vulnerability remediation requirements, and security baselines.
• Identify opportunities to improve vulnerability management processes through automation, scripting, workflow optimization, and integration with enterprise security technologies.
