Configure the threat intelligence sources included with Splunk Enterprise Security

Splunk Enterprise Security includes several threat intelligence sources that retrieve information across the Internet.

Some of these threat intelligence sources are enabled by default.

Prerequisites

• Your Splunk Enterprise deployment must be connected to the Internet. If your deployment is not connected to the Internet, disable these threat sources or source them in an alternate way.
• To set up firewall rules for these threat sources, you might want to use a proxy server to collect the threat intelligence before forwarding it to Splunk Enterprise Security and allow the IP address for the proxy server to access Splunk Enterprise Security. The IP addresses for these threat sources can change.

Steps

1. From the Enterprise Security menu bar, select Configure > Data Enrichment > Threat Intelligence Downloads.
2. Review the Description field for all defined threat intelligence sources to learn more about the types of indicators that can be correlated with your events.
3. Enable or disable the threat intelligence sources that fit your security use cases.
4. Configure the enabled threat intelligence sources that fit your security use cases, using the links to the threat source websites in the table to review the threat source provider's documentation. Each threat source website provides suggestions for polling intervals and other configuration requirements separate from Splunk Enterprise Security.

Splunk Enterprise Security expects all threat intelligence feeds to send properly-formatted data and valuable threat intelligence information. Feed providers are responsible for malformed data or false positives that could be identified in your environment as a result.

Some lists included in Splunk Enterprise Security are not added to the threat intelligence collections and are instead used to enrich data in Enterprise Security.

If you determine that your Splunk Enterprise Security installation is retrieving data from unexpected IP addresses, perform a WHOIS or nslookup to determine if the IP address matches that of one of the threat sources configured in your environment.

Next step
