Google Drive Add-On

About

This add-on allows for indexing of metadata about Google Drive usage within an organization. It captures audit events such as file creation, access, and deletion.

It also serves as an example for using OAuth to authenticate a modular input. More information can be found in Splunk's Developer Guidance

Installing

To use this add-on, you must first create an project in the Google Developers Console

1. Create a new project, giving it whatever name suits your needs.
2. In your new project, click on APIs & auth -> Credentials in the nav bar.
3. Click the Add credentials button and select OAuth 2.0 client ID
4. Follow the prompt to create a product name for your consent screen
5. Select an Application type of Other, give it a name and press Create
6. Take note of your client ID and secret

Now set up the input in Splunk:

1. As an admin, go to the Settings menu and select Data inputs
2. In the Google Drive Activity Stream row, click Add new
3. Give your input a descriptive name and remember it, as we will need it when authorizing in the next step.
4. Click More Settings
   1. Set the interval to the rate at which you want to query Google Drive. 86400 (24 hours) is a good value.
   2. Set the sourcetype to google:drive:activity
5. Save the configuration

Finally, we need to authorize the input. At the command line:

1. Ensure that the environment variable $SPLUNK_HOME is set to your Splunk installation directory

2. Run the following command (split into multiple lines for clarity):

   $SPLUNK_HOME/bin/splunk cmd python
       $SPLUNK_HOME/etc/apps/splunk-add-on-google-drive/bin/configure_oauth.py
       <input name> <client ID> <client secret>
   

   This will give you a URL that you can copy and past into a browser. Once you authenticate with your Google username and password you will get a key that you can then paste into the prompt.

3. Go back to the input you created above and disable and reenable it to kick off the modular input process immediately.
