User Guide

Configure Code42 App For Splunk

Install the App according to your environment (see steps above)
Navigate to App > IA-Code42ForSplunk > Administration > Application Configuration

Application Configuration Dashboard

To configure the Code42 application you should start on the Application Configuration page (Administration > Application Configuration)*[]:

Application Configuration

On this screen you can set the base index as well as a flag that specifies that the application is configured. In the future there will be additional configurations available.

Proxy Configuration

If you have configured a proxy server you can view the configuration under this tab. These are proxy server configurations that are being used by existing modular inputs for the Code42 application. You can also delete existing proxy configurations on this tab.

Encrypted Credentials

You can view/delete existing credentials on this tab. These are credentials that are being used by existing modular inputs in the Code42 application. These credentials are the credentials used to connect to Code42 appliances.

Code42

On this screen you can view and make any changes to existing modular inputs. As you make changes and tab between fields the modular input is modified.

Creating New Proxy Configurations

If you need to use a proxy as part of the connection to the Code42 appliance configure it here.

To create a new proxy server configuration, click the Create New Proxy button and fill in the following fields:
- Proxy Name: Name for the proxy configuration. This name will be used as the proxy name in the modular input configuration.
- Host: Proxy host name or IP.
- Port: Port used to connect to the proxy server.
- Username: Username used to connect to the proxy server.
- Password: Password for the username specified above.
- Use SSL: Should SSL be used for the proxy configuration?

Creating New Credentials

By default creating a new modular input with a username and password specified will create the necessary encrypted credentials. However if you want to create encrypted credentials manually follow this process:

To create a new encrypted credential, click the Create New Credential button and fill in with the appropriate username and password.
The realm is the application name where the encrypted credential is created + the username.

NOTE: By default creating a new modular input will automatically create a new encrypted credential so this process is not necessary unless you need a new credential for another purpose.

Creating New Code42 Inputs

NOTE: You will need to configure a new modular input for each appliance

To create a new data input, click the Create New Modular Input button and fill in the following fields. Those with a red asterisk on the screen are required.
- Modular Input Name: Name for the data input configuration.
- Hostname and port: The hostname or IP address and port of the Code42 appliance. By default you can specify hostname:443.
- Username: The username used to connect to the appliance. This user should have a of role of Security Center User, Customer Cloud Admin, or Server Admin.
- Password: The password for the previously specified username.
- Toggle all data keys: Check to select all data keys.
- Data keys: List of endpoints available on the Code42 appliance. Check the data key if you wish to pull event data.
- Historical Lookback: This is the number of days to lookback for Security Events. Default is 60.
- Interval: The number of seconds indicate how often the input will poll for new data. This setting must be at least 60.
- Index: This sets the index for data to be written to. This setting should be changed from default, which normally writes to the main index, to a specified index for best performance.
- Use Proxy: Indicates if a proxy should be use for communication with the Code42 appliance.
- Proxy Name: Enter the name of the proxy stanza to use with the input.
After creating the modular input you may need to disable/re-enable the input in Settings > Data Inputs > Code42 App For Splunk to activate the input.

NOTE: When configuring the modular input through the Application Configuration dashboard, the password is automatically encrypted into the credential store. If you need to change the credential, create a new credential, and reference the host/user pair in the modular input configuration. An encrypted credential is required for this Splunk App.

Indexes

By default all events will be written to the main index. You should change the index in the configuration files to match your specific index.
