Configure Secure Firewall App in Splunk

To ensure that the Splunk server is reachable by Cloud-Delivered Firewall Management Center and Firewall Threat Defense, and to receive the events from the device, configure the Cisco Secure Firewall App in Splunk.

Before you begin

Ensure that you have obtained a Splunk server license and a Cisco Security Cloud account.

Download and install the Splunk server using the instructions provided in Splunk Enterprise Installation Manual.

Step 2

To install Splunk license, log in to your Splunk server's web interface.

Step 3

Go to Settings > Licensing > Add license. Use the license received by email.

Note	Make sure to restart Splunk to complete license registration.

Step 4

Download Cisco Security Cloud from Splunkbase Apps.

Step 5

To install Cisco Security Cloud, log in to your Splunk server's web interface.

Step 6

Go to Apps > Manage Apps > Install app from file.

Step 7

Click Browse and select the downloaded application file and upload.

Step 8

To configure the server to receive the syslog events from the Cloud-Delivered Firewall Management Center and Firewall Threat Defense, go to Apps > Cisco Security Cloud > Secure Firewall > Configure Application, and then click the Syslog tab.

Step 9

In the Input Name field, enter any name.
