Vulnerability validation

Objective

Validate scanner findings, remove false positives, and prioritize remediation with clear owners.

Authorized scope

Only systems listed for scanning/validation. No exploit development on production without separate RoE.

Prerequisites

  • Vulnerability assessment basics
  • Authenticated scan access where approved
  • Asset criticality data
Course →Roadmap L13 →

Step-by-step workflow

  1. Step 01

    Ingest findings

    • Import scanner output
    • Deduplicate by asset + CVE/CWE
    • Tag internet-facing vs internal

  2. Step 02

    Validate

    • Confirm service/version where safe
    • Mark FP with evidence
    • Note exploitability context

  3. Step 03

    Prioritize

    • Combine CVSS/EPSS with asset criticality
    • Set SLA buckets
    • Assign owners

  4. Step 04

    Track to closure

    • Ticket each accepted risk or fix
    • Retest after patch
    • Report KPIs (open/aging)

Expected evidence

  • Raw scan export
  • Validation notes / FP proofs
  • Prioritized backlog with owners
  • Retest results

Checklist

  • Credentials for authenticated scans secured
  • FP rate measured
  • Critical internet findings escalated same day

Remediation

  • Patch or compensate critical exposures first
  • Remove unnecessary services
  • Fix recurring root causes (golden images, IaC)
