Processes Search API

Overview

This API lets you search through all the data that is reported by your organization’s sensors to find one or more processes based on specific criteria you set.

With visibility across your fleet of monitored endpoints, you can identify applications that are acting abnormally and over time, cull the outliers from the total observed process activity, and retroactively identify the origination point for attacks that previously escaped notice. You can also:

  • Test out a variety of approaches to querying your organization’s historical data before adding that query to a Watchlist
  • Get deep visibility into the security context of Windows processes including elevation, mandatory access control integrity level and privileges
  • Search across all Enterprise EDR Watchlist-hitting activity in your organization to hone in on patterns and outlier behavior

Use cases

  • Find the process that was identified in an Alert with a Process Search
  • Find processes that match targeted behavioral characteristics identified in Carbon Black or third-party threat intelligence reports with Get Report Hits
  • Find more details about processes that were potentially involved in malicious activity identified elsewhere with a Details Search on Processes
  • To get filtering terms or prevalent values, call /facet_jobs followed by /results on the /facet_jobs/ call with job_id in the request URI

Alternative solutions:

Requirements

  • Endpoint Standard or Enterprise EDR product
  • All API calls require an API key with appropriate permissions (see Authentication below)

Common Headers

Most API calls require all three headers:

  1. X-Auth-Token: (required) your authentication token is: API Secret Key/API ID
    • Example: If Adam from Company Q has the API Secret Key ABCDEFGHIJKLMNOPQRSTUVWX and the API ID of 12345678, his corresponding X-Auth-Token HTTP header is ABCDEFGHIJKLMNOPQRSTUVWX/12345678
  2. Content-Type: application/json
  3. accept: application/json

Quick Start Instructions

Asynchronous Quick Start Instructions

Many Platform Search functions are asynchronous and require a sequence of calls to start the process, check the status and retrieve the results. The following is an example of typical use:

  1. Start a search job: /api/investigate/v2/orgs/{org_key}/processes/search_jobs
  2. Receive the job_id
  3. Call /api/investigate/v1/orgs/{org_key}/processes/search_jobs/{job_id} to get search progress
  4. Repeat 3 until “contacted” equals “completed” in the response
  5. Call /api/investigate/v2/orgs/{org_key}/processes/search_jobs/{job_id}/results route to retrieve the output of the job; if you haven’t waited until “contacted” equals “completed”, the results obtained will be incomplete.
  6. The results will contain a num_found and num_available field indicating how many results were found and how many of those are able to be paginated. A search matching more results than will be returned through pagination will report num_found greater than num_available; note that this limitation occurs to prevent performance degradation with searches matching a large number of events or processes. In order to return more of the matching results, you can apply a smaller time range to your search request, or use additional or more specific criteria, then make as many additional of these subset searches as needed to fetch the entire num_found from your original search.

Process Search Pagination

Process searches aggregate events to construct the process models. The ‘approximate_unaggregated’ and ‘num_aggregated’ properties in the response provide greater insight into the processes that matched your search.

approximate_unaggregated indicates the number of matching events used to construct the processes which will be equivalent to num_found while the search finishes aggregating otherwise num_found may equal num_aggregated.

num_aggregated represents the processes that were constructed from the events which will be equal or greater than num_available. To retrieve more of the num_aggregated results adjust your criteria and/or time range, additionally if you set collapse to true in the process search creation then this will compress redundant events allowing for more results to be retrieved.

Note: If you create a broad or large time range search then Process Search Jobs can be cancelled using Cancel a Process Search

Guides & Resources

Authentication

  • Access Level: Before you create your API Key, you need to create a “Custom” Access Level:
    • for the category Search > Events > “org.search.events”, allow permission to CREATE to start a job, READ to get results, DELETE to cancel a search and UPDATE for watchlist actions. (See each call below for individual requirements)
  • API Key: When you create your API Key, use the Access Level Type of “Custom”, then select the Access Level you created.
  • Environment: use the URL of your Carbon Black Cloud console (this is the Dashboard URL) and is identified with {cbc-hostname} in the Request of each API call
  • API Route: Specific for each API call and defined in the Request section

Note: when you insert your org_key, you must also remove the { } brackets.

API calls

This API has three types of calls:

  • Calls for Processes - searches process data
  • Calls for Events - searches event data
  • Calls for Enterprise EDR - scans for hits against watchlists and reports

Note: Some calls use “v1” in the path, and others use “v2”. Using the wrong path will result in an error.

Calls for Processes

The following calls search on and return processes.

Process Search Suggestions (v1)

Returns suggestions for a process search selected from fields and values as reported in the organization’s system. Will return values for the specified field if at least one character follows the colon. Returns null if no characters follow the colon.

Retrieve Results for a Process Search (v2)

Retrieves the results of a process search identified by a job_id. Results will be sorted based on the sort parameter specified when starting the search. Confirm the search has completed by verifying that “contacted” equals “completed”.

Note: Use num_aggregated instead of num_found to determine if there are more processes which need a refined search or time range to fetch. approximate_unaggregated and num_found represent the number of matching events which are being aggregated into processes.

Calls for Events

Events search in the Processes Search API gives access to all events reported for a particular process on one endpoint.

Get Suggestions for Event Searching (v1)

Returns suggestions for an event search selected from fields from the Platform Search Fields. Will return field names if the “suggest.q” parameter does not yet contain a colon and will return no suggestion otherwise. This call does not support value suggestions.

RBAC Permissions Required

Permission (.notation name) Operation(s)

    "valid": false,
    "invalid_trigger_offset": 0
}

Get Events Associated with a Given Process (v2)

Fetch the events associated with a given process. These events are often more complete than the enriched events but, unlike the enriched event searches, must be limited to one process at a time.

Note: This call reports its progress as soon as it can and continues to enumerate process events in the background. To receive the full results, you must resubmit the request until processed_segments is equal to total_segments.

Troubleshooting & FAQ

What is a “Value Search”?

  • Platform Search supports either field:value syntax or what is called ‘value searches’ where the field name is not included e.g. where process_name:chrome.exe is a well-specified search query, a search merely for chrome.exe can return all those results as well as results where chrome.exe shows up in other fields that you didn’t have to know to specify.

What is a “hit”?

  • Enterprise EDR watchlists will report a “hit” on any process that matches on a specific IOC from one of the organization’s watchlists. These hits will be reported as process search results where the watchlist_hit field is included
  • These are separate from Alerts which are optionally reported for any watchlist hit generated by a subscribed Watchlist where “Enable Watchlist Alerts” has been set.

Why don’t I get matches on the Events APIs when I search by alert_id until a few minutes after I find the Alert?

  • The Events stream is not annotated until after the Carbon Black Cloud backend has issued an Alert, so it takes time for the Events service to process the data that identifies Events associated with Alerts. Try using a query filter that ends at least a minute or two in the past to make up for the time difference. If this latency is unacceptable, use the Data Forwarder instead.

Why are backend_timestamp and device_timestamp different? backend_timestamp is typically a few minutes later than device_timestamp due to asynchronous processing. It varies more when communications between sensor and backend are interrupted, and varies wildly if the sensor’s endpoint clock is ahead or behind. device_timestamp is pulled from the time assigned in the batch of events by the sensor before the sensor sends the events to the backend, whereas backend_timestamp is assigned by the backend as soon as it receives the batch of events.
