Upload a STIX or OpenIOC structured threat intelligence file in Splunk Enterprise Security

Upload threat intelligence in a STIX or OpenIOC file to Splunk Enterprise Security using one of the following methods:

• Upload a STIX or OpenIOC file using the Splunk Enterprise Security interface
• Add STIX or OpenIOC files using the REST API
• Add STIX or OpenIOC files using the file system

Upload a STIX or OpenIOC file using the Splunk Enterprise Security interface

Splunk Enterprise Security supports adding the following file types directly in the Splunk Enterprise Security interface:

• OpenIOC 1.0 and 1.1
• STIX 1.0, 2.0, and 2.1
• CSV

Parsing STIX documents of version 2.0 and version 2.1 parses STIX observable objects such as type: "observed-data" from the threat intelligence document as outlined in the collections.conf configuration file. The STIX pattern syntax used in STIX "indicator" objects and elsewhere is not currently supported.

To add a file in the Splunk Enterprise Security interface, complete the following steps:

1. On the Enterprise Security menu bar, select Configure > Data Enrichment > Threat Intelligence Management.
2. Click New.
3. Select IOC/STIX/STIX 2 from the drop down menu.
   This opens the Add Intelligence Document dialog.
4. Type the information for the threat intelligence document that you want to upload.
5. Click on the General tab and type a Weight for the threat intelligence file.
6. Select the Threat intelligence checkbox if you want to classify the intelligence document as threat intelligence. Classifying an intelligence document as threat intelligence triggers specific workloads. For more information on how to configure intelligence documents, see Configure intelligence documents.

   Use the tooltips provided in the UI to populate the remaining fields based on the intelligence document that you plan to upload.

7. (Optional) Click the Advanced tab and select the Sinkhole check box. This deletes the file after the intelligence from the file is processed.
8. Click Save.
