Covers discovery, [CVSS](/glossary/cvss) + rubric-based assessment, disclosure, patch validation, and QMS integration. For: Postmarket security teams, PSIRTs at medical device manufacturers, regulatory affairs, and quality leads. 7 min read Last updated Jul 10, 2026· 1mo ago Print Reviewed by [MedTech Cyber Tips Editorial Team](/authors/editorial-team) · Last reviewed July 2026 12 structured tips Checklist mode ## The walk-through 01 Technical ### Continuously monitor your SBOM against vulnerability feeds Copy link Reconcile every [SBOM](/glossary/sbom) component against NVD, CISA KEV, GitHub Security Advisories, and vendor [PSIRT](/glossary/psirt) feeds daily. Automate the diff - manual monthly reviews miss the 24-72 hour window where an exploited vulnerability becomes an FDA-reportable event. 02 Process ### Use CVSS plus a medical-device rubric, not CVSS alone Copy link [CVSS](/glossary/cvss) base scores ignore clinical impact. Layer a rubric that considers patient-safety severity, exploitability given the device's network posture, and the population of fielded devices. FDA's postmarket guidance expects both a technical score and a clinical-risk determination. 03 Process ### Establish a coordinated vulnerability disclosure (CVD) policy Copy link Publish a security.txt at your marketing domain and a plain-language [CVD](/glossary/cvd) policy: how researchers report, your acknowledgment SLA, safe-harbor language, and expected fix windows. CISA and FDA both point to ISO/IEC 29147 and 30111 as the reference model. 04 Process ### Run a PSIRT with defined SLAs Copy link Stand up a Product Security Incident Response Team with named owners, a triage queue, and SLAs by severity (e.g. critical acknowledged in 24h, mitigated in 30 days). Reviewers ask for this org chart in postmarket audits. 05 Technical ### Validate patches against the intended-use environment Copy link A patch that fixes the [CVE](/glossary/cve) but breaks a clinical workflow is worse than the vulnerability. Regression-test every patch against your verification suite, including any device-specific interoperability (DICOM, HL7/FHIR, MedRadio) before releasing. 06 Technical ### Distinguish exploitable, applicable, and reachable Copy link A CVE in a linked library may not be exploitable in your device (unused code path), may not be applicable (different config), or not reachable (no network exposure). Document the reasoning per finding in a [VEX](/glossary/vex) document so customers and reviewers can act on your actual risk, not the raw CVE count. 07 Regulatory ### Meet the EU CRA 24/72-hour reporting clock Copy link Under the Cyber Resilience Act, actively exploited vulnerabilities and severe incidents in devices sold in the EU must be reported to ENISA within 24 hours (early warning) and 72 hours (full notification). Wire this into your PSIRT runbook - the clock starts when you know, not when you fix. 08 Documentation ### Publish machine-readable advisories (CSAF) Copy link CISA and healthcare ISACs increasingly ingest CSAF 2.0 (Common Security Advisory Framework) rather than PDF bulletins. Publishing CSAF advisories accelerates [HDO](/glossary/hdo) patching and satisfies FDA's postmarket communication expectations. 09 Process ### Feed every finding back into the threat model Copy link A vulnerability that surprised you means your threat model missed a component, trust boundary, or attacker capability. Update the model and [STRIDE](/glossary/stride) analysis after every postmarket finding - this is the loop reviewers look for in a mature [SPDF](/glossary/spdf). 10 Process ### Track mean-time-to-remediate (MTTR) as a QMS metric Copy link Trend MTTR by severity in your Quality Management System. Rising MTTR is an early warning of process breakdown and shows up in FDA inspections. Set an internal target (e.g. 30 days for high, 90 for medium) and review quarterly. 11 Process ### Coordinate with HDOs on patch deployment windows Copy link Hospitals rarely patch on your schedule. Provide compensating controls (network segmentation guidance, IOC signatures, WAF rules) alongside the patch so HDOs can mitigate before their maintenance window arrives. 12 Documentation ### Retire and re-verify SBOMs on every release Copy link An SBOM is only correct for a specific build. Regenerate on every release, sign it (e.g. with Sigstore), and retire prior SBOMs from your distribution channels so customers do not scan against stale component data. ### Common pitfalls - Treating CVSS as sufficient - reviewers want a clinical-risk overlay and a fielded-population impact estimate. - No published CVD policy, so researchers escalate directly to CISA or the press instead of your PSIRT. - Patching without regression against the clinical workflow, breaking interoperability in production. - Ignoring EU CRA's 24/72-hour reporting timeline for devices distributed in the EU market. - Stale SBOMs - reconciling last quarter's SBOM against today's CVE feed misses the components you actually shipped. - Counting raw CVE numbers instead of publishing a VEX that distinguishes applicable from not-applicable findings. ### Your next steps 1. 1 Publish a coordinated vulnerability disclosure policy and security.txt at your marketing domain. 2. 2 Automate daily SBOM-to-CVE reconciliation with NVD, CISA KEV, and vendor advisories. 3. 3 Adopt a CVSS-plus-clinical-rubric scoring model and document it in the postmarket plan. 4. 4 Stand up a PSIRT with SLAs by severity and a defined escalation path to regulatory affairs. 5. 5 Publish machine-readable CSAF advisories and per-release VEX documents. 6. 6 Wire the EU CRA 24/72-hour reporting timeline into the PSIRT runbook for EU-distributed devices.
