DEFENSIVE REMEDIATION WORKFLOW

Recommended response

  1. Identify affected assets with Qualys, Tanium, software inventory, CMDB or configuration-management data.
  2. Confirm package/application applicability before change execution; CVSS alone does not prove that every host is vulnerable.
  3. Patch, upgrade, rehydrate or apply a vendor-approved mitigation through controlled change. GraceITS can automate eligible waves with Ansible/Tanium.
  4. Rescan after remediation and reconcile remaining exceptions, false positives, unsupported systems and compensating controls.
