- 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.
