Thanks For Downloading!

Review the documentation below and follow any custom installation steps. If no install steps are listed, most Splunk Apps and Add-ons can be installed as follows:

Windows: Decompress the downloaded file using a tool like 7-Zip and place the resulting folder into %PROGRAMFILES%\Splunk\etc\apps. Then restart Splunk using the splunk restart command or the GUI.

Unix/Linux: Decompress the downloaded file using a tool like tar -xvf and place the resulting folder into $SPLUNK_HOME/etc/apps. Then restart Splunk using the splunk restart command or the GUI.

RSA SecurID Appliance application for Splunk

This application was designed to give users usable data surrounding the activity taking place on their RSA SecurID appliances. This application will work with both the RSA SecurID Appliance 130 and 230 models.

Pre-deployment Assumptions:

1. The RSA appliances are configured to send SNMP traps and allow SNMP read access using SNMPv2.
2. The Splunk server is accepting SNMP traps and logging them to /var/log/snmptraps.log or the SNMP traps are being absorbed by Splunk in some manner and given a sourcetype name "snmptrap".
3. The Splunk server has SNMP access to the RSA appliance.
4. The snmpget command is installed and in your $PATH

Application Configuration:

Scripted Inputs: For the "Network Activity" view to properly work there is a scripted input that needs to be configured. This scripted input uses the snmpget command to retrieve specific values from the device. If you have multiple devices then you need to configure multiple scripted inputs. Follow these steps:

1. Copy the sample inputs.conf file from $SPLUNK_HOME/etc/apps/RSASecurID/default/inputs.conf to your local folder, just so no changes are overwritten if the application is updated.

2. Edit the inputs.conf file and change the script stanza to reflect your device configuration:

[script://$SPLUNK_HOME/etc/apps/RSASecurID/bin/getSnmpData.sh public 1.1.1.1]
disabled = 1

Change "public" to be the community name configured on your appliance that has read access. Change "1.1.1.1" to be the IP Address of your appliance. Change "disabled = 1" to "disabled = 0" to enable the scripted input.

3. If you have multiple appliances, just copy/paste the [script://] stanza for as many appliances as you have and configure the appropriate values as mentioned above.

Monitored Inputs: There is an example [monitor://] stanza in the inputs.conf file. Configure this for the proper location of the file that your SNMP traps are being logged to. If the SNMP traps are already being indexed by Splunk then this can be ignored.
