User Guide: TruSTAR for ServiceNow

Updated 3 months ago by TruSTAR

Please migrate to the TruSTAR for ServiceNow v2 App for more features and better integration with ServiceNow.

This document explains how to use the features of the TruSTAR Workflow App for ServiceNow (London and newer versions). You can use the TruSTAR App to:

  • Enrich: Quickly provide context to aid in triage and investigation of Security Incidents.
  • Manage: Conduct advanced searches for reports and indicators across all internal repositories and external sources in a single query.
  • Analyze: Add analyst notes and comments to support ongoing investigation, analysis, and collaboration.
  • Detect: Deploy internal and external intelligence to detection tools.

Features

The App automates the extraction of Observables from events and enriches them using TruSTAR intelligence sources. All enrichment - including links directly to TruSTAR’s in-depth analysis - is stored in the ServiceNow ticket. With the TruSTAR app, you can

  • Submit a Security Incident to TruSTAR
This functionality is only available if you have the ServiceNow Threat Intelligence plug-in installed. 
  • Perform Threat Lookups on Security Incidents
  • Enrich Observables found in Security Incidents.

This video is a short demonstration of how TruSTAR works with ServiceNow.

Submitting a Security Incident

To create and submit a Security Incident Response (SIR) incident to TruSTAR, you must have this plug-in enabled: ServiceNow Security Incident Response version 4.0.25 or higher. 

Use this procedure to create and submit a Security Incident Response (SIR):

  1. Select Security Incidents on the left menu.
  2. Select Incidents, then select Show All Incidents.

  1. Click New.
  2. Fill in the Short Description and Description on the Security Incident form.
  3. Click Submit to send the report to TruSTAR. 

You can now see the date of the report and a link to TruSTAR Station in the Notes field. Click on the link to view the report on TruSTAR Station.

After the report has been submitted, if you have automatic Threat Lookup and Observable Enrichment configured, the TruSTAR Integration will add observables found in TruSTAR to the Observables table in the Security Incident, with links to more information on TruSTAR Station. 

ServiceNow_UserGuide_Figure5
There is a maximum of 100 items that can be added to the Observables table for each Security Incident.

Viewing Observables

The TruSTAR platform is constantly updated with new Observables that can provide enrichment for an existing Security Incident. 

To view Associated Indicators:

  1. Select Show IOC under the Related Links subheading. You now see a list of Observables for the Security Incident.
  2. Click the Associated Indicators tab.

Using the Security Operations Integration

To use the TruSTAR Threat Lookup and Observable Enrichment features, you must have this plug-in enabled:

  • ServiceNow Threat Intelligence

Performing Threat Lookups

You can use Threat Lookup to determine the priority of an Observable. The lookup returns one of the following values:

  • HIGH (considered malicious) - displays a TruSTAR High Priority blue tag
  • MEDIUM
  • LOW
  • NOT FOUND

Before running a manual threat lookup, you need to select the Threat Lookup checkbox on the Security Operations Configuration tab:

  1. Log into ServiceNow using the Admin role.
  2. Click Configuration on the left menu.
  3. In Settings, click the Security Operation Configurations tab.
  4. Select the Threat Lookup checkbox.

Manual Threat Lookup on a Single Observable
  1. Move to the Security Incident where you want to run a Threat Lookup.
  2. Click Show IoC. This displays all TruSTAR extracted Indicators as Observables.
  3. Open the desired Observable. This opens the detail page for that Observable.
  4. Click Run Threat Lookup.
Manual Threat Lookup on Multiple Observables
  1. Move to the Security Incident where you want to run a Threat Lookup.
  2. Click Show IoC. This displays all TruSTAR extracted Indicators as Observables.
  3. Select the checkbox next to each Observable.
  4. Select Action on selected Rows from the dropdown menu.
  5. Choose Run Threat Lookup.

Checking Threat Lookup Results

You can find the result of a Threat Lookup by clicking the Threat Lookup Results tab.

To see Threat Lookup results of individual Observables, click the Threat Lookup Results tab inside that Observable.

Performing Observable Enrichment

You can enrich an Observable by collecting more data about that observable from TruSTAR. 

Note: Disabling this functionality affects only TruSTAR enrichment. Enrichment from all other security integrations installed on your instance will still work

Before running a manual observable enrichment, you need to check the Observable Enrichment box on the Security Operations Configuration tab:

  1. Log into ServiceNow using the Admin role.
  2. Click Configuration on the left menu.
  3. In Settings, click the Security Operation Configurations tab.
  4. Select the Observable Enrichment checkbox.
