Splunk Enterprise Event Ingestion integration for Security Operations by ServiceNow

The Splunk Enterprise event and alert data integration with the Security Incident Response (SIR) product allows security incident analysts to collect and process security logs and related event data.

Overview

Data is collected in real-time, and it is used by analysts to identify and report on potential cyber threats. The security events that are collected can be processed into triggered alerts that are ingested automatically with this integration. Also, individual security events can be manually forwarded on-demand from the Splunk Enterprise search and reporting interface into the Security Incident Response product of the Now Platform to create security incidents. You can retrieve notable events from Splunk Enterprise search with the search head cluster configuration. You can achieve this by using the URL and API port of any search head that is a part of the cluster.

This integration provides a security operations center (SOC) analyst with visibility to events and related alert data. This data can be integrated into Now Platform Security Incident Response (SIR) security incidents for further investigation and remediation. Profiles for Splunk ongoing ingested alerts and forwarded events are created in your Now Platform instance. These profiles customize how different Splunk alert and event fields are displayed on SIR security incidents. A default mapping of alert fields is provided that can be edited and augmented to meet customer-specific needs.

Key features

This integration includes the following key features:

  • Create multiple alert ingestion profiles to create SIR security incidents for specific types of threats such as phishing and malware.
  • Create multiple event profiles for on-demand event forwarding from your Splunk console to create SIR security incidents.
  • Drag-and-drop mapping of Splunk alert and event field values to associated SIR security incident fields.
  • A preview of the SIR security incident layout based on sample alerts or events to validate profile configuration.
  • Ingest historical alerts as well as ongoing, future alerts on configurable intervals.
  • Aggregate events or alerts to existing SIR security incidents based on matching field values to avoid duplicate security incidents.
