Cybereason Source

The Cybereason Source provides a secure endpoint to receive authentication logs from the Cybereason Malops API. It securely stores the required authentication, scheduling, and state tracking information.

States

A Cybereason 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 Cybereason 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 Cybereason.
  5. Collecting: The Source is actively collecting data from Cybereason.

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.

Authentication

You need to have a Cybereason username and password as well as your customer-specific host, such as mydomain.cybereason.net. If you have a customer-specific port this should be included, such as mydomain.cybereason.net:8443.

Create a Cybereason Source

When you create a Cybereason 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 Cybereason Source:

  1. In the Sumo Logic web app, select Manage Data > Collection > Collection
  1. On the Collectors page, click Add Source next to a Hosted Collector.
  1. Select Cybereason.

  1. Enter a Name to display for the Source in the Sumo web application. The description is optional.

  1. (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.
  2. Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM Enterprise. When configured with the Forward to SIEM option the following metadata fields are set:
Field Name Value
_siemVendor Cybereason
_siemProduct Endpoint Security
_siemFormat JSON
_siemEventID <eventType>

Where event_type is the value of the field malopDetectionType from the JSON event.
  1. (Optional) Fields. Click the +Add link to add custom log metadata Fields.
    • Define the fields you want to associate, each field needs a name (key) and value. 
      • green check circle.png A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
      • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable 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 or is disabled it is ignored, known as dropped.
  2. Cybereason Host. Provide your customer-specific host, such as mydomain.cybereason.net. If you have a customer-specific port this should be included, such as mydomain.cybereason.net:8443.

  3. User email and password. Provide the Cybereason user credentials you want to use to authenticate collection requests.

  4. (Optional) The Polling Interval is set for 300 seconds by default, you can adjust it based on your needs. This sets how often the Source checks for new data.

  5. (Optional) The Back Collection Interval allows you to set, in hours, ingestion for up to 30 days of prior MalOps.

  6. (Optional) Duplicate On Fields, when enabled, each value in the array of machines or users is put into its own log. The entire log is duplicated for each value in the array, where each log gets one value. For example,

    {
        "data": 1,
        "machine": [1, 2, 3]
    }


    Would be processed into three logs, each with a single value from the machine array, like this:

    {
        "data": 1,
        "machine": 1
    }
    {
        "data": 1,
        "machine": 2
    }
    {
        "data": 1,
        "machine": 3
    }

  7. 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 retries will be attempted every 60 minutes. 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 retries will be attempted every 60 minutes. 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.
