SplunkPy

Use the SplunkPy integration to fetch events (logs) from within Cortex XSOAR, push events from Cortex XSOAR to SplunkPy, and fetch SplunkPy ES notable events as Cortex XSOAR incidents.

This integration was integrated and tested with Splunk v6.5.

Use Cases

---

• Query Splunk for events.
• Create a new event in Splunk.
• Get results of a search that was executed in Splunk.

Configure SplunkPy on Cortex XSOAR

1. Navigate to Settings > Integrations > Servers & Services.
2. Search for SplunkPy.
3. Click Add instance to create and configure a new integration instance.

Parameter	Description	Required
host	The host name to the server, including the scheme (x.x.x.x).	True
authentication	The username used for authentication.	True
port	The port affiliated with the server.	True
fetchQuery	The notable events ES query to be fetched.	False
fetch_limit	The limit of incidents to fetch. The maximum is 200 (It is recommended to fetch less than 50).	False
isFetch	The incidents fetched.	False
incidentType	The incident type.	False
proxy	Runs the integration instance using the proxy server (HTTP or HTTPS) that you defined in the server configuration.	False
timezone	The timezone of the Splunk server (in minutes). For example, GMT is gmt +3, set +180 (set this only if it is different than the Cortex XSOAR server). This is relevant only for fetching notable events.	False
parseNotableEventsRaw	Parses the raw part of notable events.	False
replaceKeys	Replace with Underscore in Incident Fields	False
extractFields	The CSV fields that will be parsed out of _raw notable events.	False
useSplunkTime	Uses the Splunk clock time for the fetch.	False
unsecure	When selected, certificates are not checked. (not secure)	False
earliest_fetch_time_fieldname	The earliest time to fetch (the name of the Splunk field whose value defines the query's earliest time to fetch).	False
latest_fetch_time_fieldname	The latest time to fetch (the name of the Splunk field whose value defines the query's latest time to fetch).	False
app	The context of the application's namespace.	False
hec_token	The HEC token (HTTP Event Collector).	False
hec_url	The HEC URL. For example, https://localhost:8088.	False
fetch_time	The first timestamp to fetch in \<number>\<time unit> format. For example, "12 hours", "7 days", "3 months", "1 year".	False
use_requests_handler	Use Python requests handler	False

The (!) Earliest time to fetch and Latest time to fetch are search parameters options. The search uses All Time as the default time range when you run a search from the CLI. Time ranges can be specified using one of the CLI search parameters, such as earliest_time, index_earliest, or latest_time.

4. Click Test to validate the URLs, token, and connection.

Configure Splunk to Produce Alerts for SplunkPy

It is recommended that Splunk is configured to produce basic alerts that the SplunkPy integration can ingest, by creating a summary index in which alerts are stored. The SplunkPy integration can then query that index for incident ingestion. It is not recommended to use the Cortex XSOAR application with Splunk for routine event consumption because this method is not able to be monitored and is not scalable.

1. Create a summary index in Splunk. For more information, click here.
2. Build a query to return relevant alerts.
3. Identify the fields list from the Splunk query and save it to a local file.
4. Define a search macro to capture the fields list that you saved locally. For more information, click here. Use the following naming convention: (demistofields{type}).
5. Define a scheduled search, the results of which are stored in the summary index. For more information about scheduling searches, click here.
6. In the Summary indexing section, select the summary index, and enter the {key:value} pair for Cortex XSOAR classification.
7. Configure the incident type in Cortex XSOAR by navigating to Settings > Advanced > Incident Types.
8. Navigate to Settings > Integrations > Classification & Mapping, and drag the value to the appropriate incident type.
9. Click the Edit mapping link to map the Splunk fields to Cortex XSOAR.
10. (Optional) Create custom fields.
11. Build a playbook and assign it as the default for this incident type.

Commands

You can execute these commands from the Cortex XSOAR CLI, as part of an automation, or in a playbook. After you successfully execute a command, a DBot message appears in the War Room with the command details.

Get results

---

Returns the results of a previous Splunk search. This command can be used in conjunction with the splunk-job-create command.

Base Command

splunk-results

Input

Argument Name	Description	Required
sid	The ID of the search for which to return results.	Required

Context Output

There is no context output for this command.

Command Example

!splunk-results sid="1566221331.1186"

Search for events

---

Searches Splunk for events.

Base Command

splunk-search

Input

Argument Name	Description	Required
query	The Splunk search language string to execute. For example, "index=* | head 3".	Required
earliest_time	Specifies the earliest time in the time range to search. The time string can be a UTC time (with fractional seconds), a relative time specifier (to now), or a formatted time string. The default is 1 week ago, in the format "-7d". You can also specify time in the format: 2014-06-19T12:00:00.000-07:00".	Optional
latest_time	Specifies the latest time in the time range to search. The time string can be a UTC time (with fractional seconds), a relative time specifier (to now), or a formatted time string. For example: "2014-06-19T12:00:00.000-07:00" or "-3d" (for time 3 days before now).	Optional
event_limit	The maximum number of events to return. The default is 100. If "0" is selected, all results are returned.	Optional
app	The string that contains the application namespace in which to restrict searches.	Optional
batch_limit	The maximum number of returned results to process at a time. For example, if 100 results are returned, and you specify a batch_limit of 10, the results will be processed 10 at a time over 10 iterations. This does not affect the search or the context and outputs returned. In some cases, specifying a batch_size enhances search performance. If you think that the search execution is suboptimal, it is recommended to try several batch_size values to determine which works best for your search. The default is 25,000.	Optional
update_context	Determines whether the results will be entered into the context.	Optional

Context Output

Path	Type	Description
Splunk.Result	Unknown	The results of the Splunk search. The results are a JSON array, in which each item is a Splunk event.

Command Example

!splunk-search query="* | head 3" earliest_time="-1000d"
