![]() This information is now able to be correlated with Splunk Enterprise Security. Splunk Enterprise Security pulls in the information from the Alert and incorporates this information into the Splunk Enterprise Security in the Incident Review area: Here we can see that the information sent to Splunk Enterprise Security includes the Alert Identifier, the Attack Detection Pattern that was triggered that would be of interest to Splunk, the timestamps, severity level, terminal id and more. In this case, a fully formed JSON record was published to Splunk Enterprise Security: Enterprise Threat Detection supports JSON, CEF, or LEEF formats. These details will be published through the alert publishing feature to Splunk Enterprise Security. In Enterprise Threat Detection, we can see that the initiator, WDFN33984083A was able to access monitored data (sensitive data which turned out to be intellectual property – the pump architecture plans) and was able to download data as a result of the successful brute force attack: We also see the system that was acted upon identified as System ID, Actor and System ID Y13/222. We can also see the network host name initiator – WDFN33984083A who is the bad actor in this case. We can see here that the alert has a unique identifier and was triggered due to the Brute Force Attack Detection Pattern. When an attack detection pattern is triggered in Enterprise Threat Detection, an alert is issued with an alert identifier – it looks like this: First, let’s look at an alert published by Enterprise Threat Detection to Splunk. Here is how an alert from Splunk looks in Enterprise Threat Detection: There is also an out of the box connector available to Enterprise Threat Detection from Splunk Enterprise Security when it finds suspicious behavior at the infrastructure layer. ![]() This announced connectivity is an added feature that provides two-way communication with the publishing of an alert to Splunk Enterprise Security for further investigation into the event at the infrastructure level.

Receiving data over HTTP Event Collector (HEC) Record open port numbers on your deployment diagram. You can perform a network port scan on a host to determine if it is listening on a port. Splunk software uses the following network ports to communicate between its components by default or by convention. ![]() A firewall that has not been configured to allow these ports open can block communication between the Splunk instances. Splunk components communicate with each other using TCP and UDP network protocols. Splunk Enterprise components require network connectivity to work properly if they have been distributed across multiple machines, and even in cases where the components are on one machine.
