Logs

Filebeat is a lightweight shipper that enables you to send your Cisco Firepower logs to Logstash and Elasticsearch. Configure Filebeat using the pre-defined examples below to start sending and analysing your Firepower logs.

Install Integration

Please click on the Install Integration button to configure your stack for this source.

Install Filebeat

To get started you will need to install filebeat. To do this you have two main options:

To successfully install filebeat and set up the required Windows service you will need to have administrator access.

If you have chosen to download the zip file:

  • Extract the contents of the zip file into C:\Program Files.
  • Rename the extracted folder to filebeat
  • Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
  • From the PowerShell prompt, run the following commands to install filebeat as a Windows service:
cd 'C:\Program Files\filebeat'
.\install-service-filebeat.ps1

If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:

PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1

For more information about Powershell execution policies see here (opens in a new tab).

If you have chosen to download the filebeat.msi file:

  • double-click on it and the relevant files will be downloaded.

At the end of the installation process you'll be given the option to open the folder where filebeat has been installed.

  • Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
  • From the PowerShell prompt, change directory to the location where filebeat was installed and run the following command to install filebeat as a Windows service:
.\install-service-filebeat.ps1

If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:

PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1

For more information about Powershell execution policies see here (opens in a new tab).

Locate the configuration file

/etc/filebeat/filebeat.yml

Configure Filebeat.yml

The configuration file below is pre-configured to send data to your Logit.io Stack.

Copy the configuration file below and overwrite the contents of the Filebeat configuration file typically located at /etc/filebeat/filebeat.yml

####################### Logit.io Filebeat Configuration ########################
# ============================== Filebeat inputs ===============================
filebeat.inputs:
- type: udp
  max_message_size: 10MiB
  host: "0.0.0.0:514"
  enabled: true
 
  fields:
    type: ciscofirepower
  fields_under_root: true
  encoding: utf-8
  ignore_older: 12h
 
# ================================== Outputs ===================================
output.logstash:
  hosts: ["@logstash.host:@logstash.sslPort"]
  loadbalance: true
  ssl.enabled: true

It's a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com (opens in a new tab) is a great choice.

Validate Configuration

In the directory where Filebeat is installed, run the following command to validate the installation:
.\@beatname.exe test config -c @beatname.yml

If the yml file is invalid, @beatname will print a description of the error. For example, if the output.logstash section was missing, @beatname would print no outputs are defined, please define one under the output section

Configure Firepower Syslog server

You can now go ahead and configure your Cisco Firepower Firewall to write all logs to the configured agent address (syslog endpoint) you have configured.
