Falco Integration

Version	1.3.0 (View all)
Compatible Kibana version(s)	8.13.3 or higher 9.0.0 or higher
Supported Serverless project types What’s this?	Security Observability
Subscription level What’s this?	Basic
Level of support What’s this?	Elastic

This integration allows for the shipping of Falco alerts to Elastic for observability and organizational awareness. Alerts can then be analyzed by using either the dashboard included with the integration or via the creation of a custom dashboard within Kibana.

Data Streams

edit

The Falco integration collects one type of data stream:

Logs The Logs data stream collected by the Falco integration is comprised of Falco Alerts. See more details about Falco Alerts in Falco’s Outputs Documentation. A complete list of potential fields used by this integration can be found in the Logs reference

Requirements

edit

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.

Falco must be configured to output alerts to a supported output channel as defined in Setup. The system will only receive fields output by Falco’s rules. If a rule does not include a desired field the rule must be edited in Falco to add the field.

This integration is compatible with Falco version 0.37 and above, and should not be expected to perform successfully in lower versions.

Setup

edit

For step-by-step instructions on how to set up an integration, see the Getting started guide.

In order to capture alerts from Falco you must configure Falco to output Alerts as JSON to one of the supported channels: Logfile or TCP Syslog.

Required: To configure Falco to output JSON, set the config properties json_output=true and json_include_output_property=true in Falco’s config. See the examples in Falco’s Output Channels documentation.

Logfile Input

edit

The logfile input reads data from one or more Falco log files using the Elastic Agent. Use this input when the Elastic Agent will be deployed to the same machine as Falco or when Falco’s log files are available via a mounted filesystem.

To use this input Falco must be configured to output alerts to a log file. See Falco’s File Output documentation for details.

TCP Syslog Input

edit

The TCP Syslog input allows the Elastic Agent to receive Falco Alerts via remote syslog. Use this input when you want to send data via Falco Sidekick.

To use this input you will need to deploy the Elastic Agent first and then configure and deploy Falco Sidekick to send Alerts to the Agent via Syslog. See Syslog Output and Connecting Falco to Sidekick for more details.
