Add threat intelligence with a custom lookup file in Splunk Enterprise Security
You can add threat intelligence to Splunk Enterprise Security as a custom lookup file. Add a custom lookup file in this way if you want to edit the lookup file in Splunk Enterprise Security. If you want to add a lookup file to have the intelligence in it extracted once, upload the CSV file instead. See Upload a custom CSV file of threat intelligence in Splunk Enterprise Security.
A lookup-based threat source can add data to any of the supported threat intelligence types, such as file or IP intelligence. See Supported types of threat intelligence in Splunk Enterprise Security.
Create the custom CSV file. The custom file can contain multiple types of intelligence, but you must include headers for each column in the CSV file. See Supported types of threat intelligence in Splunk Enterprise Security for the headers relevant for each type of threat intelligence.
First, add the lookup to Splunk Enterprise Security.
- Select Configure > Content Management.

Next, add a threat source input stanza that corresponds to the lookup file so that ES can parse the threat intelligence.
