Configuring Netskope Connectors

This connector allows Stellar Cyber to collect data from external sources and add the records to the data lake.

Netskope integration with Stellar Cyber enables organizations to monitor and protect their cloud environment, providing real-time threat intelligence and automated response workflows to improve incident response and threat mitigation.

There can be any number of Netskope connectors active.

Stellar Cyber connectors with the Collect function (collectors) may skip collecting some data when the ingestion volume is large, which potentially can lead to data loss. This can happen when the processing capacity of the collector is exceeded.

Third Party Native Alert Integration Details

This connector ingests logs from Netskope to get the raw alerts that are stored in the Syslog index.

Stellar Cyber maps Netskope alerts. The alerts are read from the Syslog index, enriched with Stellar Cyber fields, and mapped (with deduplication) to the Alerts index.

Deduplication is by the following fields:

  • Breach—tenantid, user.name, netskopewsg.breach_id

  • Connection—tenantid, user.name, netskopewsg.connection_id

  • Malsite—tenantid, user.name, netskopewsg.malsite_id

The following types are supported:

  • Netskope Alert (Breach)

  • Netskope Alert (Connection)

  • Netskope Alert (Malsite)

For details, see Integration of Third Party Native Alerts.

Required Credentials

  • Netskope Tenant Name and API Key

Locating Records

To search the alerts in the Alerts index or to search the Original Records in the Syslog index, use the queries:

  • msg_class: netskopewsg_alert AND netskopewsg.type: breach

  • msg_class: netskopewsg_alert AND netskopewsg.type: connection

  • msg_class: netskopewsg_alert AND netskopewsg.type: malsite

               Let us know if you find the above overview useful.

Adding a Netskope Connector

To add a Netskope connector:

  1. Obtain your Netskope credentials
  2. Add the connector in Stellar Cyber
  3. Test the connector
  4. Verify ingestion

Obtaining your Netskope Credentials

Before you configure the connector in Stellar Cyber, you must obtain an API token from Netskope.

  1. Log in as an administrative user to the Netskope Admin Console, for example: https://netskope-tech.okta.com/app/UserHome.

  2. Choose Settings.

  3. Choose Tools.

  4. Choose REST API v2 to get an API token for all the available content types. (Or, you can choose REST API v1 to get an API token for the Alert and Event content types only.) Then choose NEW TOKEN.

    To select the Netskope API version that you want the connector to use, refer to the following information as a guide for selecting your Netskope endpoints. This selection must correspond to the version associated with the API token:

    V1: For this version, the following endpoints are supported:

    • /api/v1/alerts

    • / api/v1/events

    V2: For this version, the following endpoints are supported:

    • /api/v2/events/data/alert (supports data types: policy, dlp, watchlist)

    • / api/v2/events/data/application (supports data type: application)

    • /api/v2/events/data/page (supports data type: page)

    • /api/v2/steering/ipsec/pops (supports data type: pops)

    • /api/v2/steering/ipsec/tunnels (supports data type: tunnels)

  5. Select the privilege for the endpoints you want to select. At a minimum, select Read.
    For example, for REST API v2:

  6. Click Save.

Adding the Connector in Stellar Cyber

With the configuration information handy, you can add the Netskope connector in Stellar Cyber:

  1. Log in to Stellar Cyber.

  2. Click System | Integration | Connectors. The Connector Overview appears.

  3. Click Create. The General tab of the Add Connector screen appears. The information on this tab cannot be changed after you add the connector.

    The asterisk (*) indicates a required field.

  4. Choose Web Security from the Category drop-down.

  5. Choose Netskope from the Type drop-down.

  6. For this connector, the supported Function is Collect, which is enabled already.

  7. Enter a Name. This field is required, and does not accept multibyte characters.

  8. Choose a Tenant Name.

    This field does not accept multibyte characters.

  9. Choose the device on which to run the connector.

    • Certain connectors can be run on either a Sensor or a Data Processor. The available devices are displayed in the Run On menu. If you want to associate your collector with a sensor, you must have configured that sensor prior to configuring the connector or you will not be able to select it during initial configuration. If you select Data Processor, you will need to associate the connector with a Data Analyzer profile as a separate step. That step is not required for a sensor, which is configured with only one possible profile.

    • If the device you're connecting to is on premises, we recommend you run on the local sensor. If you're connecting to a cloud service, we recommend you run on the DP.

  10. (Optional) When the Function is Collect, you can apply Log Filters. For information, see Managing Log Filters.

  11. Click Next. The Configuration tab appears.

  12. Select the Netskope API Version that you want the connector to use.

    If the selected API Version is V1, the Configuration tab is as follows:

    The asterisk (*) indicates a required field.

    If the selected API Version is V2, the Configuration tab is as follows:

    The asterisk (*) indicates a required field.

  13. Choose the Content Type you would like to collect. For V1, the logs for Alert and Event are supported. For V2, the logs for Alert, Event, Page, Pops, and Tunnels are supported.

  14. Enter the Netskope Tenant Name, for example, companya.

    Do not enter a full URL, for example, companya.goskope.com.

  15. Enter the API Key you noted above in Obtaining your Netskope Credentials.

  16. Choose the Interval (min). This is how often the logs are collected. The default interval is 5 minutes.

    Pops and Tunnels information is queried every 24 hours.

  17. Choose the Interval (min). This is how often the logs are collected.

  18. Click Next. The final confirmation tab appears.

  19. Click Submit.

    To pull data, a connector must be added to a Data Analyzer profile if it is running on the Data Processor.

  20. If you are adding rather than editing a connector with the Collect function enabled and you specified for it to run on a Data Processor, a dialog box now prompts you to add the connector to the default Data Analyzer profile. Click Cancel to leave it out of the default profile or click OK to add it to the default profile.

    • This prompt only occurs during the initial create connector process when Collect is enabled.

    • Certain connectors can be run on either a Sensor or a Data Processor, and some are best run on one versus the other. In any case, when the connector is run on a Data Processor, that connector must be included in a Data Analyzer profile. If you leave it out of the default profile, you must add it to another profile. You need the Administrator Root scope to add the connector to the Data Analyzer profile. If you do not have privileges to configure Data Analyzer profiles, a dialog displays recommending you ask your administrator to add it for you.

    • The first time you add a Collect connector to a profile, it pulls data immediately and then not again until the scheduled interval has elapsed. If the connector configuration dialog did not offer an option to set a specific interval, it is run every five minutes. Exceptions to this default interval are the Proofpoint on Demand (pulls data every 1 hour) and Azure Event Hub (continuously pulls data) connectors. The intervals for each connector are listed in the Connector Types & Functions topic.

    The Connector Overview appears.

The new connector is immediately active.

Testing the Connector

When you add (or edit) a connector, we recommend that you run a test to validate the connectivity parameters you entered. (The test validates only the authentication / connectivity; it does not validate data flow).

  1. Click System | Integrations | Connectors. The Connector Overview appears.

  2. Locate the connector that you added, or modified, or that you want to test.

  3. Click Test at the right side of that row. The test runs immediately.

    Note that you may run only one test at a time.

Stellar Cyber conducts a basic connectivity test for the connector and reports a success or failure result. A successful test indicates that you entered all of the connector information correctly.

To aid troubleshooting your connector, the dialog remains open until you explicitly close it by using the X button. If the test fails, you can select the  button from the same row to review and correct issues.

The connector status is updated every five (5) minutes. A successful test clears the connector status, but if issues persist, the status reverts to failed after a minute.

Repeat the test as needed.

If the test fails, the common HTTP status error codes are as follows:

HTTP Error Code HTTP Standard Error Name Explanation Recommendation
400 Bad Request This error occurs when there is an error in the connector configuration.

Did you configure the connector correctly?

401 Unauthorized

This error occurs when an authentication credential is invalid or when a user does not have sufficient privileges to access a specific API.

Did you enter your credentials correctly?

Are your credentials expired?

Are your credentials entitled or licensed for that specific resource?

403 Forbidden This error occurs when the permission or scope is not correct in a valid credential.

Did you enter your credentials correctly?

Do you have the required role or permissions for that credential?

404 Not Found This error occurs when a URL path does not resolve to an entity. Did you enter your API URL correctly?
429 Too Many Requests

This error occurs when the API server receives too much traffic or if a user’s license or entitlement quota is exceeded.

The server or user license/quota will eventually recover. The connector will periodically retry the query.

If this occurs unexpectedly or too often, work with your API provider to investigate the server limits, user licensing, or quotas.

For a full list of codes, refer to HTTP response status codes.
