Collect Splunk CIM logs
This document describes how you can collect Splunk Common Information Model (CIM) logs by configuring Splunk and a Google Security Operations forwarder. This document also lists the supported log types and supported Splunk versions.
For more information, see Data ingestion to Google Security Operations.
Overview
The following deployment architecture diagram shows how Splunk agents are configured to send logs to Google Security Operations. Each customer deployment might differ from this representation and might be more complex.
The architecture diagram shows the following components:
Data source: The system to be monitored in which Splunk is installed.
Splunk: Collects information from the data source and forwards the information to Google Security Operations forwarder.
Google Security Operations forwarder: A lightweight software component, deployed in the customer's network to forward the logs to Google Security Operations.
Google Security Operations: Retains and analyzes the logs from the Fleet server.
An ingestion label identifies the parser which normalizes raw log data
to structured UDM format. The information in this document applies to the parser
with SPLUNK ingestion label.
Before you begin
Use Splunk version 5.0 that Google Security Operations parser supports.
Ensure that all systems in the deployment architecture are configured in the UTC time zone.
Configure a Splunk agent and a Google Security Operations forwarder
Install a CIM compliant agent from Splunkbase.
Configure Google Security Operations forwarder to push the logs into the Google Security Operations system. The following is an example of a Google Security Operations forwarder configuration:
- splunk: common: enabled: true data_type: SPLUNK batch_n_seconds: 10 batch_n_bytes: 819200 url: <SPLUNK_URL> query_cim: true is_ignore_cert: true query_string: datamodel Network_Traffic All_Traffic flat
Considerations for writing Splunk search queries
Splunk has its own search language, which is similar to SQL. Make sure you use the correct syntax for your search query. Consider the following search characteristics when you create a query:
Escape character
If a string value contains a double quotation mark ", use backslash characters to escape the quotation mark. Otherwise, the search misinterprets the end of the string value.
For example: To search a string WHERE _raw="The user "vpatel" isn't authenticated.",
you must use the sequence \" to search for a literal double quotation mark.
Write the search string in the following format:
WHERE _raw="The user \"vpatel\" isn't authenticated."
To escape a backslash character \ , use the sequence \\ to search for a backslash.
For example, if there is a string like C:\user\abc then this must be written as C:\\user\\abc.
Syntactically incorrect search
If a section of the query is invalid, the entire query is not evaluated and an error message appears.
Consider the following example in which the search mode option is missing in the query:
multisearch [|datamodel Network_Traffic All_Traffic] [|datamodel Network_Sessions All_Sessions flat]
In this example, the search mode option is missing in the query. This results in the following error:
Error in 'multisearch' command: Multisearch sub searches might only contain purely streaming operations. The search job has failed due to an error.
Support for multiple data models
Splunk supports a single large query that spans data models. The following search query extracts data from multiple data models:
multisearch [|datamodel Network_Traffic All_Traffic flat] [|datamodel Network_Sessions All_Sessions flat]
Here are the components of this query that spans data models:
Multisearch: The query must start with the word multisearch. A query for a data model must be enclosed within square brackets [ ] and start with a pipe | character.
Network_Traffic: The name of the data model.
All_Traffic: Dataset of Network_Traffic data model.
flat: Search mode. The other options are search and acceleration_search.
We recommend using the following Splunk query for multiple data model search:
multisearch [|datamodel Network_Traffic All_Traffic flat] [|datamodel Network_Sessions All_Sessions flat]
