Create an asset lookup from your current LDAP data in Splunk Enterprise Security

Use the Lightweight Directory Access Protocol (LDAP) to register your assets, create a lookup, and schedule a search to run on a regular basis.

Prerequisites
This requires the Splunk Supporting Add-on for Active Directory for access to the | ldapsearch command. See Extract asset and identity data in Splunk Enterprise Security.

To get started with the Asset and Identity Builder, do the following:

1. From the Splunk Enterprise Security menu bar, select Configure then Datasets, then Asset and identity management.
2. Select the Asset Lookups tab.
3. Select New.
4. Select the LDAP Lookup from the drop-down menu.

Search

In the search section, do the following to name the lookup generating search:

1. Provide a unique name for the search.
2. Provide your LDAP domain.

Once you have provided your LDAP domain, you will see messages in the custom search builder preview, such as "InvalidLDAPSearchSpec: Valid LDAP search specifications must supply a lookup." This message is normal at this point.

Lookup

In the lookup section, do the following:

1. Provide a lookup label for your search-driven lookup.
2. Provide a unique lookup name and/or transform name.
3. The lookup filename .csv will auto-complete based on the name you provided for the lookup name.

Search schedule

Once you have completed the lookup fields, the custom search builder preview will show the search it has created. Select Run search to verify if the search returns results.

In the search schedule section, do the following to run the search on a regular basis:

1. Enter a cron schedule.
2. Select Real-time or Continuous scheduling.
3. Select Save.

This saves two things:

• Saved searches that you can find in Content management
• Lookup table and lookup definition that you can find in Settings > Lookups

Asset management

The next step is where you begin to create the settings stored in the inputs.conf file that points to the lookup and pulls the data every 5 minutes to make updates to the asset or identity collections.

Since this example is for an asset, the next window that pops up is the New Asset Manager.

1. The Source is auto-populated with the name of the lookup that you provided.
2. See Asset Lookup Configuration.
