    Summary of Data Transformation for the Patch Orchestration Integration with HCL BigFix

    This document outlines the data transformation process for integrating HCL BigFix with ServiceNow's Vulnerability Response patch orchestration. It details how data from various sources, including computer assets and fixlets, is imported and transformed within the ServiceNow AI Platform.

    Key Features

    • BigFix Collection Import: Data from computers and computer groups is imported into the BigFix Collection Import table using the BigFix Computer and Computer Groups Import transform map. Modifications to this map affect data processing.
    • BigFix Fixlet Import: Fixlet data is imported into the BigFix Fixlet Import table. The associated transform map is crucial for accurate data handling.
    • BigFix Device Fixlet Import: Relevant fixlet data related to devices is loaded into the BigFix Device Fixlet Import table, utilizing the appropriate transform map.
    • BigFix Actions Import: Action data is imported into the BigFix Actions Import table, with transformation managed by the corresponding import transform map.

    Key Outcomes

    By leveraging these import and transformation processes, ServiceNow customers can:

    • Effectively manage and respond to vulnerabilities in their IT environment by integrating data from HCL BigFix.
    • Maintain accurate and up-to-date Configuration Items (CIs) through automated data processing and transformation scripts.
    • Ensure comprehensive visibility into the status of patches and actions across their systems.

    All transformation scripts are marked for internal use and should remain unaltered to ensure functionality and integrity of the integration.

    Data is retrieved from the Vulnerability Response patch orchestration with HCL BigFix integration, processed through a set of data sources, and transformed in your ServiceNow AI Platform® instance.

    BigFix Collection import

    The data from the imported assets (computers and computer groups) are loaded into the BigFix Collection Import [sn_vul_bigfix_collection_import] table. The BigFix Computer and Computer Groups Import TM (transform map?) is used to transform the imported information.
    Note:
    Changes to this transform map alter how data from the BigFix Collection import is processed.
    To access this transform map, navigate to System Import Sets > Transform Maps and locate BigFix Computer and Computer Groups Import TM. The following table lists the transform map fields by integration.
    Table 1. BigFix Computer and Computer Groups import transform map script timing
    Script Description
    OnStart (when an import set has created transformation). Script used to initialize the values in the scope variable [sn_vul_bigfix] for the integration process. This script is for internal use and should not be modified or deleted.
    onBefore (before an import set has completed transformation).

    Script used to create and update CIs based on CI Lookup Rules and collections as well as relation between them. Based on the results, this script modifies the values in the scope variable [sn_vul_bigfix]. This script is for internal use and should not be modified or deleted.
    onComplete (when an import set has completed transformation). Script that is used to set the number of CIs created, updated, and ignored. This script is for internal use and should not be modified or deleted.

    BigFix Fixlet import

    The data from the imported fixlets are loaded into BigFix Fixlet Import [sn_vul_bigfix_patch_update_import] table.

    BigFix Fixlet Import TM is used to transform the imported information.

    Note:
    Changes to this transform map alter how data from the BigFix Fixlet import is processed.

    To access this transform map, navigate to System Import Sets > Transform Maps and locate the BigFix Fixlet Import TM.

    The following table lists the transform map fields by integration.

    Table 2. BigFix Fixlet import transform map fields

    Table 3. BigFix Fixlet import transform map script timing
    Script Description
    OnStart (when an import set has created transformation). Script that is used to initialize the values in the scope variable [sn_vul_bigfix] for the integration process. This script is for internal use and should not be modified or deleted.
    onBefore (before an import set has completed transformation).

    The script that is used to update the values in the scope variable [sn_vul_bigfix]. This script is for internal use and should not be modified or deleted.
    onComplete (when an import set has completed transformation). Script that is used to set the number of fixlets created, updated, and ignored. This script is for internal use and should not be modified or deleted.

    BigFix Device Fixlet Import

    The data from the imported relevent fixlets on computers are loaded into the BigFix Device Fixlet Import [sn_vul_bigfix_device_patch_import] table.

    BigFix Device Fixlet TM is used to transform the imported information.

    Note:
    Changes to this transform map alter how data from the BigFix Device Fixlet import is processed.
