Devo Query

Overview

Devo SIEM is a cloud-based data logging and security analytics platform designed to improve access to security data across an enterprise. Security teams have access to real-time and historical data to quickly respond to their organization’s threat landscape. This integration allows organizations to query and manage alerts as well as other data sources.

Devo Query is available for use in:

With the Devo Query integration, D3 SOAR can:

• Automatically ingest events from Devo’s alert tables after configuring scheduled jobs in the Fetch Event command.

• Normalize event log data from Devo after configuring field extraction mapping for better visibility of ingested Devo alerts on D3’s Investigation Dashboard.

• Automatically perform initial enrichment, data cleansing, and correlation on ingested Devo alerts to determine whether they are potential threats with the default Event Playbook. Events marked as threats will be further processed as incidents in an Incident Playbook.

• Execute the Run Query command to gain contextual information for dynamic incident investigations with the ad-hoc command feature. The Run Query command can also be used as automated Incident Playbook tasks.

Integration API Note

For more information about the Devo Query API, please refer to the Devo Query API reference.

Reader Note

Certain permissions are required for each command. Please refer to the Permission Requirements and Configuring Devo Query to Work with D3 SOAR for details.

Integration Designed Query

Some commands require structured input arguments in Language Integrated Query (LINQ). LINQ syntax is similar to that of SQL. Refer to LINQ query examples from Devo’s documentation for detail.

To fit the LINQ query into D3 SOAR commands’ input arguments, you can omit some duplicated inputs. An example of an original LINQ query is as follows:

from siem.logtrust.alert.info

where priority >=1.0 and context = "my.alert.partner_domain.CrowdstrikeAlert"

select * limit 10

The corresponding inputs for integration commands in D3 are as follows:

Note for Time-related parameters

The input format of time-related parameters may vary based on your account settings. As a result, the sample data provided in our commands is different from what you see. To set your preferred time format, follow these steps:

1. Navigate to Configuration > Application Settings. Select Date/Time Format.

   

2. Choose your desired date and time format.

   

After that, you will be able to view your preferred time format when configuring the DateTime input parameters for commands.

Fetch Event

Returns events from Devo SIEM based on specified query criteria.

Reader Note

If the input is 10 minutes later than the current time for the End Time parameter, the current time will be used. This prevents the command from idling until future events have taken place.

The number of events returned is limited by defining the search criteria. If not specified, all events within the specified time range of the query will be returned. It is recommended to limit the number of events returned because the command might timeout.

Fetch Event Field Mapping

Please note that Fetch Event commands require event field mapping. Field mapping plays a key role in the data normalization process part of the event pipeline. Field mapping converts the original data fields from the different providers to the D3 fields which are standardized by the D3 Model. Please refer to Event and Incident Intake Field Mapping for details.

If you require a custom field mapping, click +Add Field to add a custom field mapping. You may also remove built-in field mappings by clicking x. Please note that two underscore characters will automatically prefix the defined Field Name as the System Name for a custom field mapping. Additionally, if an input Field Name contains any spaces, they will automatically be replaced with underscores for the corresponding System Name.

As a system integration, the Devo Query integration has some pre-configured field mappings for default field mapping.

• Default Event Source
  The Default Event Source is the default set of field mappings that are applied when this fetch event command is executed. For out-of-the-box integrations, you will find a set of field mapping provided by the system. Default event source provides field mappings for common fields from fetched events. The default event source has a “Main Event JSON Path” (i.e., $.object) that is used to extract a batch of events from the response raw data. Click Edit Event Source to view the “Main Event JSON Path”.

  

  • Main Event JSON Path: $.object
    The Main Event JSON Path determines the root path where the system starts parsing raw response data into D3 event data. The JSON path begins with $, representing the root element. The path is formed by appending a sequence of child elements to $, each separated by a dot (.). Square brackets with nested quotation marks ([‘...’]) should be used to separate child elements in JSON arrays.
    For example, the root node of a JSON Path is object. The child node denoting the Unique Event Key field would be alertId. Putting it together, the JSON Path expression to extract the Unique Event Key is $.object.alertId.

The pre-configured field mappings are detailed below:
