How do you integrate external threat intelligence into Splunk ES?

Integrating external threat intelligence into Splunk Enterprise Security (ES) is effectively accomplished by utilizing threat intelligence feeds within the Threat Intelligence Framework. This framework is specifically designed to ingest and normalize information from various threat intelligence sources. By leveraging these feeds, organizations can enhance their ability to detect, investigate, and respond to potential security threats based on real-time, actionable intelligence.

Using threat intelligence feeds allows Splunk ES to correlate this data against existing logs and alerts, improving the accuracy of threat detection and enriching security incident analysis. This integration streamlines the operational workflow by automatically updating threat profiles and allowing analysts to focus on actionable alerts rather than manual data entry or analysis.

The other options do not provide the comprehensive capabilities that the Threat Intelligence Framework offers. Manually entering threat data lacks the efficiency and scalability of automated feeds. Relying solely on internal assessments might not capture the full spectrum of external threats, and utilizing third-party analytics tools may not integrate seamlessly into the Splunk environment, potentially missing the full context of security incidents. Thus, the correct choice reflects the most integrated and efficient method for managing external threat intelligence within Splunk ES.
