Refresh Timing Risks: CVE Exposure in Aging Servers
🔍 A healthcare customer bought servers in 2017 and, due to COVID-era lifecycle extensions and current supply-chain bottlenecks, now faces expiring vendor support and long lead times that prevent timely hardware refresh. The article recommends building a complete inventory using scanners (Nessus, Qualys, Rapid7, Greenbone/OpenVAS), network discovery (Nmap) and device fingerprinting (runZero), then mapping assets to NVD and CISA Known Exploited Vulnerabilities (KEV). Use a weighted risk formula to prioritize remediation and sort systems into immediate, managed, and monitored tiers. Document risk acceptance, deploy compensating controls where needed, and consider continuous monitoring with Wazuh.
