See the CI matching in Vulnerability Response knowledge base article \[[KB0998706\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0998706) for more information about CI matching rule concepts and how CI matching works. - **[View and reclassify unmatched configuration items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/view-discovered-items.md)** Configuration items \(CIs\) that are not found in the Configuration Management Database \(CMDB\) are placed in a viewable list of discovered items. This list offers a convenient way to reclassify unmatched CIs. - **[Reconcile unmatched discovered items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/reapply-reconcile-unmatched-discovered-items.md)** Create a scheduled job to reconcile unmatched discovered items. - **[Steps to help prevent duplicate or orphaned records after running Vulnerability Response CI lookup rules](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/ci-identifier-rules-impl-test.md)** Take steps to help prevent duplicate or orphan records resulting from matching \(configuration items \(CIs\) within the CMDB. - **[De-duplicating existing configuration items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/reapply-deduplication.md)** Whenever configuration items \(CIs\) are updated through a deduplication task, the discovered items \(DIs\) that are related to those CIs are also updated. The vulnerable items \(VIs\) and detections are also updated with the CI. - **[Resolve remediation tasks](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/remediate-vuln-groups.md)** The flexibility inherent in Vulnerability Response allows you to remediate vulnerabilities in whatever way suits your security organization. **Parent Topic:**[Vulnerability Response remediation overview](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/security-management/vulnerability-response/cj-common-vuln-tasks.md)
