The patch management lifecycle
Inventory and scan: know what you run and what is missing. Prioritize: rank by severity, exploitability, and business exposure. Test: validate patches in pre-production before production. Deploy and verify: roll out in batches, confirm success, report compliance.
Firmware: the layer OS patch tools cannot reach
Windows and Linux patch tooling is mature; the layer beneath it is not. BIOS/UEFI, BMC firmware, RAID controller firmware, and NIC firmware each carry their own CVEs — and OS-level patch tools see none of them and fix none of them. Key advantages: collect firmware versions from every BMC, flag baseline-compliance drift, batch-roll out over out-of-band channels, a single view across brands, and auditable patch records.
FAQ
Software patch management is the process of identifying, testing, and deploying OS and application updates. Automated patch management uses tools to scan for missing patches, apply them by schedule or policy, and report compliance. Firmware patches update the code beneath the OS — a layer OS patch tools cannot touch. Patch management vs vulnerability management: vulnerability management finds and prioritizes weaknesses; patch management fixes the subset that has a patch available.
