Crowdstrike FDR Source

The CrowdStrike Falcon Data Replicator (FDR) Source provides a secure endpoint to ingest Falcon Data Replicator events using the S3 ingestion capability by consumed SQS notifications of new S3 objects. It securely stores the required authentication, scheduling, and state tracking information.

info

The CrowdStrike API documentation is not public and can only be accessed by partners or customers.

This Source is available in the Fed deployment.

Historical data

If you have already enabled Crowdstrike FDR you can have a queue of up to seven days worth of data. This historical data is ingested by the CrowdStrike FDR Source. This can be avoided by not enabling FDR in the Crowdstrike portal until you're ready to configure the Crowdstrike FDR Source. If you have enabled FDR and do not want to ingest the historical data, contact Customer Support for guidance.

States

A CrowdStrike FDR Source tracks errors, reports its health, and start-up progress. You’re informed, in real-time, if the Source is having trouble connecting, if there's an error requiring user action, or if it is healthy and collecting by utilizing Health Events.

A CrowdStrike FDR Source goes through the following states when created:

1. Pending: Once the Source is submitted it is validated, stored, and placed in a Pending state.
2. Started: A collection task is created on the Hosted Collector.
3. Initialized: The task configuration is complete in Sumo Logic.
4. Authenticated: The Source successfully authenticated with CrowdStrike.
5. Collecting: The Source is actively collecting data from CrowdStrike.

If the Source has any issues during any one of these states it is placed in an Error state.

When you delete the Source it is placed in a Stopping state, when it has successfully stopped it is deleted from your Hosted Collector.

On the Collection page, the Health and Status for Sources is displayed. Use Health Events to investigate issues with collection. You can click the text in the Health column, such as Error, to open the issue in Health Events to investigate.

Hover your mouse over the status icon to view a tooltip with details on the detected issue.

Prerequisite

You must contact the CrowdStrike support teamto enable CrowdStrike FDR. If it's not enabled, your requests will receive HTTP 500 responses.

Authentication

Once enabled, in the CrowdStrike console, navigate to Support > API Clients and Keys. You need to Create new credentials to copy the AWS Access Key ID, AWS Secret Access Key, and SQS Queue URL to provide to Sumo Logic when creating your CrowdStrike FDR Source.

Create a CrowdStrike FDR Source

When you create a CrowdStrike FDR Source, you add it to a Hosted Collector. Before creating the Source, identify the Hosted Collector you want to use or create a new Hosted Collector. For instructions, see Configure a Hosted Collector.

To configure a CrowdStrike FDR Source:

1. In Sumo Logic, select Manage Data > Collection > Collection. 

2. On the Collectors page, click Add Source next to a Hosted Collector.

3. Select CrowdStrike FDR.

   

4. Enter a Name for the Source. The description is optional.

   

5. (Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called _sourceCategory.

6. Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM Enterprise. When configured with the Forward to SIEM option no fields are set.

7. (Optional) Fields. Click the +Add Field link to define the fields you want to associate, each field needs a name (key) and value.

   •  A green circle with a check mark is shown when the field exists in the Fields table schema.
   •  An orange triangle with an exclamation point is shown when the field doesn't exist in the Fields table schema. In this case, an option to automatically add the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema it is ignored, known as dropped.

8. AWS Access Key ID: Provide your AWS Access Key ID you copied from CrowdStrike, see the Prerequisite.

9. AWS Secret Access Key: Provide your AWS Secret Access Key you copied from CrowdStrike, see the Prerequisite.

10. SQS Queue URL. Provide your SQS Queue URL you copied from CrowdStrike, see the Prerequisite.

11. S3 Region. Select the S3 Region your data is in, this normally is the same region specified in the SQS Queue.

12. When you are finished configuring the Source click Submit.

Error types

When Sumo Logic detects an issue it is tracked by Health Events. The following table shows the three possible error types, the reason the error would occur, if the Source attempts to retry, and the name of the event log in the Health Event Index.

Type	Reason	Retries	Retry Behavior	Health Event Name
ThirdPartyConfig	Normally due to an invalid configuration. You'll need to review your Source configuration and make an update.	No retries are attempted until the Source is updated.	Not applicable	ThirdPartyConfigError
ThirdPartyGeneric	Normally due to an error communicating with the third party service APIs.	Yes	The Source will retry for up to 90 minutes, after which it quits.	ThirdPartyGenericError
FirstPartyGeneric	Normally due to an error communicating with the internal Sumo Logic APIs.	Yes	The Source will retry for up to 90 minutes, after which it quits.	FirstPartyGenericError

JSON configuration 

Sources can be configured using UTF-8 encoded JSON files with the Collector Management API. See how to use JSON to configure Sources for details. 

Parameter	Type	Required	Description	Access
config	JSON Object	Yes	Contains the configuration parameters for the Source.
schemaRef	JSON Object	Yes	Use {"type":"Crowdstrike FDR"} for a CrowdStrike FDR Source.	not modifiable
sourceType	String	Yes	Use Universal for a CrowdStrike FDR Source.	not modifiable

The following table shows the config parameters for a CrowdStrike FDR Source.

Parameter	Type	Required?	Default	Description	Access
name	String	Yes		Type a desired name of the Source. The name must be unique per Collector. This value is assigned to the metadata field _source.	modifiable
description	String	No	null	Type a description of the Source.	modifiable
category	String	No	null	Type a category of the source. This value is assigned to the metadata field _sourceCategory. See best practices for details.	modifiable
fields	JSON Object	No		JSON map of key-value fields (metadata) to apply to the Collector or Source. Use the boolean field _siemForward to enable forwarding to SIEM.	modifiable
secretAccessKey	String	Yes		The AWS Secret Access Key you got from CrowdStrike.	modifiable
SqsQueueURL	String	Yes		The SQS Queue URL you got from CrowdStrike.	modifiable
accessKeyId	String	Yes		The AWS Access Key ID you got from CrowdStrike.	modifiable
s3Region	String	Yes	other	The S3 Region your data is in.	modifiable
