Data Collection

Barracuda Cloudgen Firewall side

You need to configure Barracuda Cloudgen Firewall to forward Syslog messages.

1. Go to CONFIGURATION -> Full Configuration -> Box -> Infrastructure Services -> Syslog Streaming.
2. Click Lock.
3. Set Enable Syslog Streaming to yes.
4. Click Send Changes and Activate.
   For more information, see here

• Important: To ensure logs are ingested and modeled correctly, you must configure the log message structure to be key=value pairs. Please follow the steps below:

1. Go to CONFIGURATION -> Full Configuration -> Box -> Infrastructure Services.
2. Look for Activity Log Mode.

3. Change the mode to Log-Pipe-Separated-Key-Value-List. This tells the firewall to format its log entries with pipes separating the key=value pairs (e.g., key1=value1

   key2=value2).

4. After changing general firewall configuration settings, perform a Firmware Restart (CONTROL -> Box) for the changes to take effect.

Cortex XSIAM side - Broker VM

To create or configure the Broker VM, use the information described here.

Follow the below steps to configure the Broker VM to receive Barracuda Cloudgen Firewall logs.

1. Navigate to Settings → Configuration → Data Broker → Broker VMs.
2. Go to the APPS column under the Brokers tab and add the Syslog app for the relevant broker instance. If the Syslog app already exists, hover over it and click Configure.
3. Click Add New.

4. When configuring the Syslog Collector, set the following parameters:

   Parameter	Value
   Protocol	Select UDP for the default forwarding, TCP or Secure TCP (depends on the protocol you configured in Barracuda Cloudgen Firewall).
   Port	Enter the syslog service port that Cortex XSIAM Broker VM should listen on for receiving forwarded events from Barracuda Cloudgen Firewall.
