How Splunk Enterprise Security processes and merges asset and identity data
Splunk Enterprise Security takes the asset and identity data that you add as lookups and generates combined lookup files. Splunk Enterprise Security uses the generated lookup files to correlate asset and identity data with events using automatic lookups. The following steps describe this process at a high level.
- You collect asset and identity data from data sources using an add-on and a custom search or manually with a CSV file. See Collect and extract asset and identity data.
- You configure any settings in the identity lookup configuration setup. See Define identity formats on the identity configuration page.
- The Splunk Enterprise Security identity manager modular input updates settings in the
- You format the data as a lookup, using a search or manually with a CSV file. See Format the asset or identity list as a lookup.
- You configure the list as a lookup table, definition, and input. See Configure a new asset or identity list.
- The Splunk Enterprise Security identity manager modular input detects two things:
- Changed content in the
- Changes to stanzas in the input.
inputs.conf. For example, the
`generate_identities`macro dynamically updates based on the conventions specified on the Identity Lookup Configuration page.
- The primary saved searches concatenate the lookup tables referenced by the identity manager input, generate new fields, and output the concatenated asset and identity lists into target lookup table files.
- Secondary saved searches generate lookup tables for asset categories, identity categories, and asset PCI domains (in the Splunk App for PCI Compliance).
The merging of identity and asset lookups does not validate or de-duplicate input. Errors from the identity manager modular input are logged in
identity_manager.log. This log does not show data errors.
