  VULNERABILITY REMEDIATION – INCIDENT RESPONSE FROMVULNERABILITY DETECTION TO CONTAINMENT, REMEDIATION & RECOVERY
• 2.
  WHAT IS VULNERABILITY REMEDIATION? Typical Flow- Detect→ Assess → Prioritize → Remediate → Validate → Monitor Key points: Identify vulnerabilities through tools such as Qualys, Tenable/Nessus, Rapid7 Assess CVSS, exploitability, asset criticality and business impact Apply patch or other mitigation Validate that the vulnerability is closed Continue monitoring for exploitation attempts

  END-TO- END INCIDENT Scenario: Critical vulnerability detected → Exploitation suspected→ Response initiated. Step 1 — Detection Step 2 — Risk Assessment Step 3 — Exploitation Detection Step 4 — Containment Step 5 — Eradication & Remediation Step 6 — Valiation

  KEY TAKEAWAYS /LESSONS LEARNED • 5 Key Takeaways • Not every vulnerability is an incident. • Prioritize vulnerabilities based on risk + exploitability + asset criticality. • If exploitation is suspected, move from vulnerability management to incident response. • Use SIEM + EDR + vulnerability management together for effective detection and response. • After remediation, always validate through rescanning and monitoring.
