![]() ![]() Preconfigurationīefore the start, we should have configured Splunk instance. Installing and configuration of ASA Firepower integration Step 1. Because the add-on installs on the heavy forwarder and provides only log collection, the other part is eStreamer eNcore app for Splunk which provides log transformation, and data model log mapping to CIM, and consists of many dashboards for monitoring. Another one is to create Splunk Heavy Forwarder in your corporate network with the possibility of an add-on to access FTD and FMC devices directly.Īs we understand the version of Splunk Cisco eStreamer eNcore add-on and app (the new one) is developed for the second scenario.But we haven’t tested it, so maybe it won’t work. The first one is to organize Destination NAT, or port forwarding on the core router for your Firepower Threat Defense appliance.There are two possible solution methods here: Your Splunk wouldn’t have the possibility to communicate with your device directly. Here one interesting thing could appear – if you have installed Splunk in the cloud (such as AWS, Azure, or Google Cloud) and have an office, which is located in a business center where your local network is hosted behind the NAT with one white IP address for many companies. There is one important thing here – FTD and FMC should be in one network as Splunk with eStreamer add on. You can find the latest version by the links belowĮStreamer Splunk solution which is available for Cisco Firepower customers running FMC version 6.x – Splunk Cisco eStreamer eNcore add-on and app. How to Configure eStreamer to Connect to Splunk Check the eStreamer latest versionįirst of all, we found the Splunk Add-on for eStreamer. Need to use Heavy forwarder (or instruction from BONUS) for each next device.Integration with an app (dashboards, alerts from the box).So we are about to share our experience of configuration log collection based on eStreamer protocol. That’s why there are many recommendations to use eStreamer protocol for log collection instead of syslog. The other feature of using this method is that communication between devices is encrypted over SSL. The client application initiates the data stream by submitting request messages, which specify the data to be sent, and then controls the message flow from the Defense Center or managed device after streaming begins. Your client can request event and host profile data from a Defense Center, and intrusion event data only from a managed device. The FireSIGHT System Event Streamer (eStreamer) uses a message-oriented protocol to stream events and host profile information to the client application. ![]() When we first heard about this method, there were many problems with perl modules and other technology which was used by the Splunk eStreamer Add-on. The other way is sending logs via eStreamer. And as we read on forums, if we use syslog there, fewer dashboards will be riched by default. On the other hand, we should manually create all necessary alerts via Cisco Firepower Management Center. ![]() Even Splunk doesn’t advise you to use it if there is another way in place. If we are talking about Cisco Firepower syslog configuration, first of all, it’s not a very reliable way to send logs. So let’s review possible methods of sending logs from Firepower Threat Defense to Splunk. But when we started reviewing possible methods, we found new opportunities to provide this. There was an add-on that was written in Perl and during the configuration process, you received too many errors and had no idea how to manage it. When the necessity of log collection from Cisco Firepower appeared, guys who did it before said that it was a really difficult task. Also, this integration includes all necessary staff for data models mapping, so you will be able to install the app with correlation rules, and turn on CR you are interested in.įirst of all, we are about to share some notes about the preparation for this task. There are a lot of dashboards that can be useful for your SOC/NOC. It will help you to monitor your network. That is why it is one of the most important log sources for your SIEM solution. The Main Reason to Connect CISCO Firepower eStreamer to Splunk SIEMĬisco ASA FirePower is Next Generation Firewall. In this article, we are going to describe the process of connecting Cisco FirePower Threat Defense with Splunk in the case of using the Cisco Firepower Management Center. ![]()
