Detailed system requirements

This section provides comprehensive information on the system requirements for Integration Services. Prior to service deployment, it is necessary for the user to possess the access outlined below.

BigFix Service Account Requirements

  • Admin access (not SOAP role admin access)

To facilitate the import of ServiceNow CMDB data into BigFix, a Master Operator account is required. Otherwise, the minimum account requirements to send BigFix endpoint data to ServiceNow are the following:

  • A non-master operator account with permissions against the in-scope computers.

  • Read access to the BigFix ServiceNow Data Flow site.

  • The Can use REST API setting set to Yes

  • The Can Create Actions setting set to No.

ServiceNow Service Account Requirements

  • Read and write access for CMDB_CI_COMPUTERS , SYS_CHOICE and CORE_COMPANY tables

  • The ServiceNow Administrator should have a service account that leverages basic authentication with read and write access to the CMDB tables.

Important: While running the BigFix ServiceNow integration from ServiceNow to BigFix, it's crucial to ensure that user roles align with the table's Access Control List (ACL) for successful attribute extraction. If there's a mismatch between user roles and the table's ACL, users may encounter instances of empty data.
