Netskope WebTx Source

The Netskope WebTx API integration ingests Web Transaction logs from Netskope Event Stream.

States

A Netskope WebTx API 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.

An Netskope WebTx API 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 Symantec.
  5. Collecting. The Source is actively collecting data from Symantec.

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 a count of the detected errors and warnings.

You can click on the status icon to open a Health Events panel with details on each detected issue.

Data Sources

The netskope-webtx access a PubSub lite service hosted by Google to retrieve web transaction logs. Details on what is ingested can be found here

Setup and Configuration

Netskope Web Transactions integration needs to be configured using Netskope Streaming credentials. You can collect the subscription path and credentials here

Create an Netskope WebTx API Source

When you create an Netskope WebTx API 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 an Netskope WebTx API Source:

  1. In Sumo Logic, select Manage Data > Collection > Collection.
  2. On the Collection page, click Add Source next to a Hosted** **Collector.
  3. Select Netskope WebTx API.
  4. Enter a Name to display the Source in the Sumo web application. 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, the following metadata fields are set:
Field NameValue
_siemVendorNetskope
_siemProductWebTx
_siemFormatJSON
_siemEventIDwebtx
  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.
      • A green circle with a check-mark is shown when the field exists and is enabled in the Fields table schema.
      • 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. You will need a subscription endpoint URL and subscription key to access the streamed events. Log in to your Netskope UI and go to Settings > Tools > Event Streaming. Copy your subscription endpoint and generate your download key from the Event Streaming page.

The REGENERATE ENDPOINT button generates a new subscription path. After a new subscription path is generated, a new subscription key must be generated by clicking on the GENERATE AND DOWNLOAD KEY button. The old subscription path and key expire. With a new subscription path, event streaming will start fresh from the beginning of the retention period which is 7 days by default.

  1. After the transaction events feature is enabled in your account, you’ll be able to consume the data from the subscription endpoint.
  2. To receive the events from the subscription, refer to the Receiving messages from Lite subscriptions link. You can receive messages with various Client libraries. Netskope retains transaction events for seven days by default if not consumed.
  3. When you are finished configuring the file, upload the JSON file.

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.

TypeReasonRetriesRetry BehaviorHealth Event Name
ThirdPartyConfigNormally 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 applicableThirdPartyConfigError
ThirdPartyGenericNormally due to an error communicating with the third party service APIs.YesThe Source will retry for up to 90 minutes, after which it quits.ThirdPartyGenericError
FirstPartyGenericNormally due to an error communicating with the internal Sumo Logic APIs.YesThe 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.
