    Summary of Vulnerability Response Remediation Overview

    Vulnerability Response remediation is a structured, phased approach aimed at verifying import completion, triaging new vulnerabilities, and monitoring remediation progress. This method helps streamline the remediation process, making it more manageable and automated. It is essential for understanding your security posture and identifying critical vulnerabilities that require attention.

    To implement this process effectively, you must have Vulnerability Response and a third-party integration, such as the Qualys Vulnerability Integration, installed and configured.

    Key Features

    • Verify Third-Party Integration Imports: Ensure successful completion of imports from third-party sources, which provide essential data for creating vulnerable items and remediation tasks. Regular monitoring of integration status is crucial for identifying issues.
    • Triage Vulnerabilities: Review new vulnerabilities and their associated vulnerable items (VI). Assign risk levels and set remediation targets, adjusting rules as necessary to ensure effective triage.
    • Monitor Progress: Keep track of remediation efforts, monitor the status of imports, and verify compliance with regulatory obligations. Use Performance Analytics for Vulnerability Response to analyze trends and measure remediation success.

    Key Outcomes

    By following this structured remediation process, ServiceNow customers can expect improved management of vulnerabilities, timely responses to critical issues, and enhanced visibility into their security posture. Successful implementation leads to more efficient remediation efforts and better alignment with compliance requirements.

    Vulnerability Response remediation is a phased process consisting of verifying import completion, triaging new vulnerabilities, and monitoring progress to completion. Approached in this way, remediation becomes manageable, timely, and in many ways, automated.

    Understanding your security posture across company assets helps you identify the most critical vulnerabilities for remediation. This remediation process requires that Vulnerability Response and a third-party integration such as the Qualys Vulnerability Integration are installed and configured.

    Verify the successful completion of third-party integration imports

    The first phase in this process is to ensure that everything is working correctly. Vulnerability Response is preset to download National Vulnerability Database (NVD) and Common Enumeration Weakness (CWE) vulnerabilities. Third-party imports provide you with the data you need to create vulnerable items and remediation tasks. Successful remediation depends on the consistent and successful import of vulnerabilities and vulnerable items.

    During import CI Lookup Rules match third-party assets to assets in the Configuration Management Database (CMDB). All assets are stored in the Discovered Items module. CI information is critical to solution implementation.

    Note:
    Once a third-party integration has been installed and configured, there are few instances where an import can fail, for example, if the third-party vendor throttles their API calls. When imports do fail, they require prompt attention.

    Integration status run reports for the supported third-party integrations are shipped with the applications to give you a graphical overview of your imports. Use this report, or create your own, to easily determine whether your latest import has succeeded. For more information about supported integrations, see Vulnerability Response integrations.

    Review and triage vulnerabilities and vulnerable items

    The next phase of remediation calls for the review of new vulnerabilities and vulnerable items. A vulnerable item (VI) is a detected combination of vulnerability and configuration item (CI). As vulnerable items are formed, various rules are run that assign VIs, determine the risk they pose and set remediation targets. Adjust any rules, as necessary, to ensure that the vulnerable items have been triaged successfully.

    Monitor the progress of existing vulnerability remediation

    The final phase of remediation consists of monitoring your progress.
    • Review the status of imports for patch implementations that have not shown up and follow up with IT Operations.
    • Track the progress of regulatory compliance obligations and ensure their completion.
    • Review deferred item status and revise or implement fixes.
    • Monitor Vulnerability Management dashboards. To review trends, view reports in real-time, and use metrics that track your remediation target attainment rates, you may prefer to monitor your processes with the Performance Analytics for Vulnerability Response application.
