Configuring Cato Networks Connectors

Connectors allow Stellar Cyber to collect data from external sources and add it to the data lake. You create one instance of this connector for each Cato Networks account you want to monitor.

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.

Connector Overview: Cato Networks

Adding a Cato Networks Connector

To add a Cato Networks connector:

1. Enable Cato API access
2. Add the connector in Stellar Cyber
3. Test the connector
4. Verify ingestion

Enabling Cato API Access

As part of this procedure, you specify the credentials of an account on the Cato server that will be used to retrieve data.

1. Log in to your Cato Networks account as the user you want to monitor.

2. Display the user's profile to verify the account type. Click the user button at the top right of the console, and then clicking My Profile. The user role must be Editor.

   

3. Obtain the Account ID by noting the URL that displays when the console loads.

   

4. Navigate to Administration > API Management.

5. Click the button for a New key.

6. In the dialog that displays, enter an identifying Name for the key, then click Apply.

   

7. When the key is created, a dialog with the value displays. Click the Copy button to copy your API key and ensure you save it to a secure location.

   After you close the dialog you can no longer access the value of the API key.

8. Click OK to close the API key dialog.

Enable Event Integration

To send Cato events data to a third party application:

1. Navigate to Administration > API & Integrations.

   

2. In API & Integrations, click the API Keys tab and then Events Integration.

3. In Events Integration, toggle Enable integration with Cato events to enabled.

   

Adding the Connector in Stellar Cyber

To add the Cato Networks connector in Stellar Cyber:

1. Log in to Stellar Cyber.

2. Click System | Connectors (under Integrations). 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 SASE from the Category drop-down.

5. Choose Cato Networks from the Type drop-down.

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

7. Enter a Name.

   Notes:

   • This field does not accept multibyte characters.
   • It is recommended that you follow a naming convention such as tenantname-connectortype.

8. Choose a Tenant Name to specify which tenant is permitted to use this connector on Stellar Cyber.

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.

    

    The asterisk (*) indicates a required field.

12. Enter the Account ID you obtained from the Cato Networks login, above.

13. In the API Key field, enter the value you saved above.

14. Enter the Interval (min). This is how often the logs are collected.

15. Select the Content Type:

    • Audit Log
    • Connectivity
    • Routing
    • Security
    • Sockets Management
    • System

16. (Optional) This Initial Marker field is used to adjust the ingestion start point in cases where the volume of Event data to retrieve is extremely large. (The default duration Cato Network’s API retrieves is 7 days of Event data.) The API supporting this field requires an encoded base64 string (combining topic, partition, and offset) that is unique to your active events queue. Stellar Cyber has provided this field for use only by advanced API users of Cato Networks who are already familiar with retrieving this marker value in their environment. (This marker does not apply to Audit type data.)

17. Click Next. The final confirmation tab appears.

    

18. Click Submit.

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

19. 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 authentication and connectivity).

1. Click System | Connectors (under Integrations). The Connector Overview appears.

   

2. Locate the connector by name 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.

Verifying Ingestion

To verify ingestion:

1. Click Investigate | Threat Hunting. The Interflow Search tab appears.

2. Change the Indices to Syslog. The table immediately updates to show ingested Interflow records.
