CrowdStrike Falcon Endpoint Protection

thumbnail icon

The CrowdStrike Falcon Endpoint Protection App provides visibility into the security posture of your endpoints as analyzed by the CrowdStrike Falcon Endpoint Protection platform. The app allows you to analyze indicators of compromise (IOCs) by affected users, tactic, technique, and objective, and identify hosts on your network with the highest malware detections. The dashboards in this app help identify threats and incidents, from which you can drill down to investigate further.

The CrowdStrike Falcon Endpoint Protection Platform is a cloud-native framework that protects endpoints to stop breaches and improve performance with the robust power of the cloud combined with an intelligent, lightweight endpoint agent.

This version of the CrowdStrike Falcon Endpoint Protection App and its collection process has been tested with SIEM Connector Version 2.1.0+001-siem-release-2.1.0.

Log Types

The CrowdStrike Falcon Endpoint Protection App uses the following log types:

  • Detection Event
  • Authentication Event
  • Detection Status Update Event

For more information on Events, please refer to the CrowdStrike Falcon Endpoint Protection Streaming API Event Dictionary.

Collecting Logs for the CrowdStrike App

This section shows you how to configure log collection from CrowdStrike Falcon Endpoint Protection and have them sent to Sumo Logic. CrowdStrike Falcon Endpoint Protection provides endpoint detection and response, next-gen antivirus, and threat intelligence services through the cloud. Multiple security functions are consolidated into a single lightweight agent, for visibility across using central security analytics with Sumo Logic.


To collect logs from CrowdStrike Falcon Endpoint Protection, if you are not using the Sumo Logic FedRamp deployment, use the new Cloud to Cloud Integration for Crowdstrike to create the source and use the same source category while installing the app.

The sections below are deprecated for non-FedRamp Sumo Logic deployments. If you're using the Sumo Logic FedRamp deployment, use the sections below to configure the collection for this app.

Collection process overview (DEPRECATED)

SIEMs (Security Information and Event Management) are used to gather data from a variety of security products to detect, investigate, correlate, and remediate security threats. The Falcon SIEM Connector provides a fast and efficient way to optimize collection across an extensive number of endpoints.


Sumo Logic recommends installing the SIEM Connector and Sumo Logic Collector on the same machine for best performance.

To set up log collection for CrowdStrike Falcon, you'll download, install, and configure the CrowdStrike SIEM Connector to send data to Sumo Logic, through performing the following tasks.

Data collection flow (DEPRECATED)

The following graphic illustrates the Sumo Logic collection of CrowdStrike streaming API events using a SIEM Connector.

Before you begin (DEPRECATED)

It is important that you complete the following tasks before you start to configure log collection for CrowdStrike Falcon:

  • Download the SIEM Connector guide, familiarize yourself with SIEM Connector and its config settings.
  • Contact CrowdStrike support to enable the streaming APIs in your environment. You must do this before using the SIEM connector.

Step 1. Download and install CrowdStrike SIEM Connector on a host machine (DEPRECATED)

You perform this procedure from the Falcon console. You must have permission to be able to download and install from Falcon to complete this task.

To install a CrowdStrike SIEM Connector on a host machine, do the following:

  1. Login to your Falcon console and go to Support > Tool Downloads.
  2. Download the SIEM Connector installer for your operating system.
  3. Open a terminal window.
  4. Run the following installation command appropriate for your OS, replacing the <installer package> variable with the SIEM installer you downloaded:
  • CentOS: sudo rpm -Uvh <installer package>
  • Ubuntu: sudo dpkg -i <installer package>

Step 2. Configure CrowdStrike SIEM Connector (DEPRECATED)

This SIEM connector will stream events data from CrowdStrike Falcon Cloud in JSON format into a local file (output). The default location of the output file is /var/log/crowdstrike/falconhoseclient/output.

To configure CrowdStrike SIEM Connector, do the following:

  1. In the Falcon console go to Support > API Clients & Keys.
  2. Create an API client to use with the SIEM connector, and record its API client ID and API client secret. In the the Edit API client dialog, ONLY select the Event streams option, and then click Save.
    1. Open the /opt/crowdstrike/etc/cs.falconhoseclient.cfg file in a text editor.
    2. Edit the following lines in the cs.falconhoseclient.cfg file:
    • Change app_id to SIEM-Connector.
    • client_id - Add your recorded API Client ID
    • client_secret - Add your recorded API Client Secret
    • Make sure output_format is set to json
    • For EventTypeCollection section - Enable all events:
      • DetectionSummaryEvent = true
      • AuthActivityAuditEvent = true
      • UserActivityAuditEvent = true
      • HashSpreadingEvent = true
      • RemoteResponseSessionStartEvent = true
      • RemoteResponseSessionEndEvent = true
    1. Save your changes.
    2. Restart the SIEM Connector, as appropriate for your OS:
    • CentOS: sudo service cs.falconhoseclientd start
    • Ubuntu 14.x: sudo start cs.falconhoseclientd
    • Ubuntu 16.4: sudo systemctl start cs.falconhoseclientd.service

Step 3. Set up a Sumo Logic installed collector and local file source (DEPRECATED)

You setup a Sumo Logic installed collector on the same host as the SIEM Connector. Then, set up a local file source on the installed collector to read the output file from Step 2 and send CrowdStrike Falcon Events to Sumo Logic.

To set up an installed collector and local file source, do the following:

  1. Install a Sumo Logic collector on the same host as the SIEM Connector. Follow the instructions for your operating system as described in Installed Collectors.
  2. Add a local file source to the collector for Streaming API Events. Follow the steps on Local File Source, with these additional changes:
  • Set the Filepath to: /var/log/crowdstrike/falconhoseclient/output
  • Set the Source Category to: crowdstrike/falcon
  • Under Enable Multiline Processing, check Boundary Regex and enter the following regex: ^\{.*.
  1. Click Save.

For more information about the CrowdStrike Falcon SIEM Connector, see the CrowdStrike documentation, or contact CrowdStrike Customer Support at

Installing the CrowdStrike Falcon Endpoint Protection App

This section provides instructions for installing the Sumo App for CrowdStrike Falcon Endpoint Protection, as well as examples for each of the app dashboards.

To install the app:

  1. From the Sumo Logic navigation, select App Catalog.
  2. In the Search Apps field, search for and then select your app.
  3. Optionally, you can scroll down to preview the dashboards included with the app. Then, click Install App (sometimes this button says Add Integration).

    If your app has multiple versions, you'll need to select the version of the service you're using before installation.

  4. On the next configuration page, under Select Data Source for your App, complete the following fields:
    • Data Source. Select one of the following options:
      • Choose Source Category and select a source category from the list; or
      • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. For example, _sourceCategory=MyCategory.
    • Folder Name. You can retain the existing name or enter a custom name of your choice for the app.
    • All Folders (optional). Default location is the Personal folder in your Library. If desired, you can choose a different location and/or click New Folder to add it to a new folder.
  5. Click Next.
  6. Look for the dialog confirming that your app was installed successfully.

Once an app is installed, it will appear in your Personal folder or the folder that you specified. From here, you can share it with other users in your organization. Dashboard panels will automatically start to fill with data matching the time range query received since you created the panel. Results won't be available immediately, but within about 20 minutes, you'll see completed graphs and maps.

Viewing CrowdStrike Falcon Dashboards

Filter with template variables

Template variables provide dynamic dashboards that can rescope data on the fly. As you apply variables to troubleshoot through your dashboard, you view dynamic changes to the data for a quicker resolution to the root cause. You can use template variables to drill down and examine the data on a granular level. For more information, see Filter with template variables.
