Supported types of threat intelligence in Splunk Enterprise Security

Splunk Enterprise Security supports several types of threat intelligence. The supported types of threat intelligence correspond to the KV Store collections in which the threat intelligence is stored.

The threatlist modular input parses downloaded and uploaded files and adds indicators to these collections. Files can contain any combination of indicators.

Threat collection in KV Store	Supported IOC data types	Local lookup file	Required headers in lookup file with no spaces after commas
certificate_intel	X509 Certificates	Local Certificate Intel	certificate_issuer,certificate_subject,certificate_issuer_organization,certificate_subject_organization,certificate_serial,certificate_issuer_unit,certificate_subject_unit,description,weight
email_intel	Email	Local Email Intel	description,src_user,subject,weight
file_intel	File names or hashes	Local File Intel	description,file_hash,file_name,weight
http_intel	URLs	Local HTTP Intel	description,http_referrer,http_user_agent,url,weight
ip_intel	IP addresses	Local IP Intel	description,ip,weight
	domains	Local Domain Intel	description,domain,weight
process_intel	Processes	Local Process Intel	description,process,process_file_name,weight
registry_intel	Registry entries	Local Registry Intel	description,registry_path,registry_value_name,registry_value_text,weight
service_intel	Services	Local Service Intel	description,service,service_file_hash,service_dll_file_hash,weight
user_intel	Users	Local User Intel	description,user,weight

The collections.conf file in the DA-ESS-ThreatIntelligence subdirectory lists these KV Store collections.

The inputs.conf.spec file in the SA-ThreatIntelligence subdirectory lists the specifications for headers, such as weight:

weight = <integer>
* [Required]
* The weight assigned to the intelligence.
* Between 1 and 100.
* A higher weight will result in higher risk scores for corresponding intelligence matches.
* Defaults to 60.
