Validating Vulnerability Remediation

(OBJ .)

Remediation

• Involve installing patches, reconfiguring devices, or other actions
• Check Vulnerability Response and Remediations

Rescanning Devices

• Conduct post-remediation scans to double-check vulnerability mitigation
• Identify any remaining unaddressed vulnerabilities
• Detect new vulnerabilities that may have emerged since the initial scan
• Validate whether applied patches effectively solved the identified vulnerabilities
• Suggestions
  • Schedule automatic re-scans and maintain consistency with initial scan conditions
  • Use comprehensive scans
  • Replicate initial scan conditions

Auditing Devices

• Auditing
  • Involves systematic review of logs, configurations, and patches
  • Ensures alignment with established security standards and policies
• Configuration Auditing
  • Checks for misconfigurations or deviations
• Patch Auditing
  • Confirms proper application and effectiveness of patches
• Maintain detailed records of vulnerabilities, patches, and changes
• Use automated auditing tools and include compliance checks for industry regulations or standards

Verification of Devices

• Verification
  • Final step in validating remediation
  • Involves testing systems to confirm patches and configuration changes
• Conduct penetration tests to verify vulnerability remediation
• User Verification
  • Ensures applications and services are functioning correctly
• Establish feedback loops with users and staff to identify and address post-remediation issues
• Perform
  • Holistic testing
  • Continuous monitoring
  • Consider external auditors for verification
• Verify both the resolution of vulnerabilities and overall system stability and functionality
