This topic explains options for adding an external data source to provide additional information in alerts. Enrichment sources provide additional information in alerts. For example, an in-memory table can provide a full name, title, office location, and employee number if a user matches rule criteria. The following types of enrichment sources are available:
- Context Hub List (Preferred)
- In-Memory Table (Ad hoc only)
It is preferable to use Context Hub List enrichment sources instead of In-Memory Table enrichment sources. You can share Context Hub List enrichment sources across the NetWitness Platform. You can only use the In-Memory Table with ESA. Recurring In-Memory Tables are no longer supported; use Content Hub Lists as enrichment sources.
