What does "Data Enrichment" mean in Splunk ES?

Data enrichment in Splunk Enterprise Security refers to the process of enhancing raw event data with additional contextual information. This augmentation is crucial for improving the quality and depth of analysis performed on the data. By adding context, analysts can gain deeper insights into the events being monitored, which ultimately helps in threat detection, incident response, and overall security monitoring.

This additional information can come from various sources, including threat intelligence feeds, user behavior analytics, or contextual data about assets and vulnerabilities. Enriching data enables security teams to make more informed decisions by providing a broader understanding of the security landscape and enabling them to correlate events more effectively.

Other options are not aligned with the concept of data enrichment. Archiving data focuses on long-term storage rather than enhancing data for analysis. The application of machine learning for predicting future threats is a separate analytical approach that does not specifically involve enhancing raw data. Lastly, compressing data for storage is about optimizing space rather than enriching the context of the data itself.
