Carbon Black Predictive Security Cloud (PSC) Integration with Security Validation

This integration collects events generated by Carbon Black Predictive Security Cloud to test the efficacy and configuration of the security control using Security Validation jobs.

API Calls

Supported Versions

• AppServices API v6
• Investigate API v2

Before You Begin

To configure this integration, you need:

• Org Key: This is found in your Carbon Black product console from Settings > API Access > API Keys.
• API Key
• API ID

Create an API Key and API ID

1. Log in to your Carbon Black product console
2. Navigate to the Settings | API Access | API Keys tab
3. Click Add API Key from the far right of the screen
4. Give the API Key a unique name, and select the /appservices/and /investigate/ access levels
5. Click Save, the API Secret Key and API ID values are displayed.
6. Copy and paste these values to a safe location.

Configure Security Validation

1. Go to Settings > Integrations.

2. From the Integrations table, click Add Integration > Carbon Black PSC.
   You can add this as either a Direct or Remote Integration.
3. Enter a meaningful Integration Name.
4. Optional: From the Proxy drop-down, choose a proxy profile if one is available. If one isn't available and all outbound connections go through a proxy, first, set up a Proxy Rule.
5. Optional: Change the Protocol value to determine what protocol is used for requests (Https or Http).
6. Enter the Host value (hostname or IP address) for the Carbon Black PSC instance. The default is defense.conferdeploy.net.
7. Enter a Port value. The default is 443.
8. Enter the Org Key value that you generated.
9. Enter the Api Id and Api Key values that you generated.
10. Optional: Check Verify Ssl if you want this verification done for requests to an upstream server.
11. Optional: Change the Timeout value if you want a different frequency of requests to an upstream server. The default is 30 (seconds).
12. Add or remove value for Queries. A default Hostname Query is provided.
13. Optional: Select any of the following checkboxes, as needed. See the Carbon Black PSC documentation for more information.
    • Enable Threat Cause
    • Enable Device Data
    • Enable Enriched Events
14. Optional: Modify the Page Size to change the request for the upstream server. The default is 1000.
    
15. Optional: Modify the Field Map values, as necessary.
    • Each field map box can hold a JSON-formatted comma-separated list of columns returned by the API to be considered for each field when translating into the normalized event object format. Example: description could be configured to be 'msg_s' or 'SyslogMessage' in some environments. The field map tries both if set to: ['msg_s','SyslogMessage'] and whichever matches first is the column that is used.
    • When configuring an integration in Security Validation, you can assign additional host values in the Field Map settings. If none of the assigned fields return a valid host name, Network Actions may miss matched events from the third-party technology. Additional hosts values helps ensure the likelihood of a match between the two environments.

16. Optional: Expand Advanced options and update the information as necessary.

    1. Update Query Time and Delay Time.
       The Query time is the amount of time (minutes) before and after the query runs that the platform looks for events, while the Delay time is the amount of time (minutes) that the platform waits to run the first query after a Job Action starts. For example, you configure your integration with the following values: Query time = 5, Query interval = 30 seconds, and Delay time = 0. When a Job Actions starts at 12:00:00, the first time the query runs, the platform looks for events from 11:55:00 to 12:00:00. Then 30 seconds later, it looks for events from 11:55:30 to 12:00:30. This interval continues, with the last query looking from 12:00:00 to 12:05:00. If you instead configured the Delay time to equal 10, it would run the same query, but it wouldn't start that query until 12:10:00.
       If your monitors are set to run more frequently than the query time, this configuration impacts the pass/fail results for AEDA monitors.
    2. Update Query Interval (seconds).
    3. If supported by your integration, configure correlation queries:
       1. Select Correlation Query Enabled and fill in the Correlation Query.
       2. Modify the Correlation Query Interval, if necessary (minutes).
    4. Select Discover network devices automatically, the default and recommended option.
       If unselected, reported events won't include product information for any matching network security technology.
    5. Select Save Suspicious Events.
    6. Modify the Event Time Adjustment (seconds). The default is 0.

    7. Modify the Limit value if you need to prevent a flood of results. This value is set to 10000 by default. This limit applies to both events and alerts individually, so if you set it to 10, you can still see a maximum of 10 events and 10 alerts.

17. Click Save.

Verify connectivity

1. Go to Settings > Integrations.
2. From the Direct Integrations table, click  > Test to verify that:
   • The Director can communicate with the integration host on the port and protocol specified.
   • The integration credentials are valid and working.
