• Review existing vulnerability reports supplied by authorized internal or external sources; identify affected servers, operating systems, applications, services, and infrastructure components.
• Determine whether findings apply to the environment and identify duplicates, false positives, previously remediated items, or findings mitigated by existing controls.
• Research vendor advisories, patch guidance, release notes, upgrades, configuration changes, and other corrective options; evaluate compatibility, downtime, dependencies, testing, and rollback requirements.
• Prioritize findings with the IT Manager and relevant system owners based on severity, exploitability, exposure, system criticality, business impact, compliance requirements, and available mitigations.
