    Summary of CI Lookup Rules for Microsoft Defender for Cloud Integration and Palo Alto Prisma Cloud

    The CI Lookup rules module enables the identification of resource types in the Configuration Management Database (CMDB) for Microsoft Defender for Cloud and Palo Alto Prisma Cloud integrations. These rules are essential for mapping applications and their releases, ensuring that all assets are uniquely identified by their object ID, cloud account, and logical datacenter in ServiceNow.

    Key Features

    • Object ID Formats: Different formats are used to populate the Objectid column for various resource types. Using the correct format is crucial for accurate asset lookup.
    • CI Lookup Rules: Predefined rules exist for common resource types, such as AWS::S3::Bucket and AWS::ElasticLoadBalancing::LoadBalancer, facilitating easier identification of CIs.
    • Custom Rules: If existing rules do not yield results, customers can create custom CI lookup rules tailored to their specific resource types.
    • Order of Execution: Priority can be set for CI lookup rules, allowing customers to control which rules are applied first based on their order value.

    Key Outcomes

    By effectively utilizing CI lookup rules, ServiceNow customers can ensure accurate asset identification within the CMDB, enhancing their ability to manage and monitor cloud resources. Customers can expect improved matching results for various resource types when using the correct object ID formats and defining appropriate lookup rules tailored to their needs.

    You can use the configuration item (CI) lookup rules for the Microsoft Defender for Cloud Integration and Palo Alto Prisma Cloud integrations to find a correct match to commonly used resource types in the Configuration Management Database (CMDB).

    Overview

    The CI Lookup rules module contains the rules that help you to define the fields that have the matching data in the Configuration Management Database (CMDB). You can use these rules to identify the applications and application releases. All Microsoft Defender for Cloud Integration and Palo Alto Prisma Cloud assets are uniquely identified by the combination of their object ID, cloud account, and logical datacenter in the ServiceNow platform. ServiceNow discovery populates the resource ID in the Object_id column of the CMDB in different formats for the different resource types. The following table shows the object ID formats of commonly used resource types that the discovery service uses to populate in the Object_id column of the CI. Any scanner that wants to look up an asset of a particular resource type must search by using the right object ID format. You can get the right object ID format by looking into the object ID column of corresponding CMDB CI class and then try to construct the object ID using the values that are received from scanner.
    Table 1. Object ID format for various resource types
    Resource Type Format
    AWS::EC2::Instance Object ID
    AWS::ElasticLoadBalancing::LoadBalancer Load balancer name
    AWS::S3::Bucket arn:aws:s3:::<Bucket Name>

    The CI match for a test result may not be found accurately in the Configuration Management Database (CMDB) unless the same format of the object_id is used in the lookup rule. Most of the times, the OOB CI lookup rules find a match for the most commonly used resource types for Microsoft Defender for Cloud Integration and Palo Alto Prisma Cloud. If the following CI lookup rules aren’t finding the CIs in the CMDB for your test results, you can create a CI lookup rule for a resource type. For more information on how to create a CI lookup rule, see Create a CI lookup rule.

    CI lookup rules

    The following CI lookup rules are specific to the Microsoft Defender for Cloud Integration and Palo Alto Prisma Cloud.
    S3 Bucket
    This lookup rule attempts to find the CI in the CMDB by the value that was obtained by concatenating the arn:aws:s3::: and resource name. The obtained value is looked up in the object_id column of the cmdb_ci_cloud_object_storage table. This lookup rule applies only when the resource type is AWS::S3::Bucket.​
    Name
    This lookup rule attempts to find the CI in the CMDB by name. The name, which is looked up in the Object_id column of the CI class, corresponds to a resource type in the sn_capi_resource_type table.
    Note:
    For the Palo Alto Prisma Cloud application, this CI lookup rule runs only for the AWS::RDS::DBInstance, AWS::ElasticLoadBalancing::LoadBalancer, and AWS::CloudTrail::Trail resource types​. You can add the resource types that you want to execute this CI lookup rule for.
    Resource Id
    This lookup rule attempts to find the CI in the CMDB by the resource ID. The resource ID, which is looked up in the Object_id column of the CI class, corresponds to a resource type in the sn_capi_resource_type table.
    Note:
    You can set the priority for a CI lookup rule in the Order field. The CI lookup rule with the least order value is executed first.
