One Identity Safeguard for Privileged Sessions 6.0.6 - REST API Reference Guide

Splunk integration

SPS can forward session data to Splunk near real-time. Using the One Identity Safeguard for Privileged Sessions App for Splunk you can integrate this data with your other sources, and access all your data related to privileged user activities from a single interface. To configure SPS to forward session data to Splunk, complete the following steps.

Prerequisites and restrictions:

• SPS version 5 F5 or later

• Splunk version 6.5 or later

• SPS does not send historical data to Splunk, only data from the sessions started after you complete this procedure.

Configure Splunk forwarder

1. Install the One Identity Safeguard for Privileged Sessions App for Splunk to your Splunk installation. This will automatically enable and configure the HTTP Event Collector (HEC) in your Splunk installation, and create an HTTP Event Collector authentication token ("HEC token") that SPS will use.

   To help identify the source of the received data, the following settings are configured automatically in the One Identity Safeguard for Privileged Sessions App for Splunk:

   • index: The One Identity Safeguard for Privileged Sessions App for Splunk creates the index automatically, with the name balabit_events.

   • sourcetype: The source type of the events the SPS fowards is balabit:event.

2. On your Splunk interface, navigate to Settings > Data inputs > HTTP Event Collector. Copy the Token Value from the Balabit_HEC field. This is the HTTP Event Collector authentication token and you will need it when configuring SPS.

3. Create the JSON object that configures SPS to forward session data to Splunk.

   POST the JSON object to the https://<IP-address-of-SPS>/api/configuration/management/splunk_forwarder endpoint. You can find a detailed description of the available parameters listed in Elements of remote_desktop_gateway. For example,

   {
       "enabled": true,
       "flush_interval": 600,
       "host":
           { "selection": "fqdn", "value": "splunk.example.com" },
       "pam_address":
           { "selection": "fqdn", "value": "psm.example.com" },
       "port": 8088,
       "ssl":
           { "selection": "insecure" },
       "token": "2134356431"
   }

4. Commit your changes.

   For details, see Commit a transaction.

5. Splunk will display the data received from SPS as it was received from the host set in the pam_address field. By default, this is the hostname and domain name of the SPS appliance as set on the /api/configuration/network/naming endpoint. Adjust this field as needed for your environment.

6. Start a session that SPS will audit to test your configuration, and verify that the data of the session appears in Splunk.

Splunk integration

The universal SIEM forwarder can automatically send data about the audited sessions to Splunk, ArcSight, or other third-party systems. The messages are standard syslog messages in RFC3164 format (also called legacy-syslog or BSD-syslog format). The body of the syslog message (the MESSAGE part) can be formatted as JavaScript Object Notation (JSON), Common Event Format (CEF), or JSON-CIM format. For information about the details of the messages that the universal SIEM forwarder sends to the external SIEM network elements, see Message format forwarded to SIEMs.

One of the main advantages of the universal SIEM forwarder is that it has a lower impact on network and performance.

Each message contains the minimal information relevant to the event. Use the built-in correlation feature of the SIEM to combine events by session ID and view all information in one place.

Manage Safeguard for Privileged Sessions clusters

When you have a set of two or more Safeguard for Privileged Sessions (SPS instances in your deployment, you can join them into a cluster. This has several advantages. You can:

• Manage the nodes from one central location.

• Monitor their status and update their configuration centrally.

• Search all session data recorded by all nodes in the cluster on a single node.

• Scale the performance of the cluster by adding new nodes and joining them to the cluster easily.

• Extend auditing to other networks by adding new nodes to the cluster and joining them to the cluster.

This is achieved by assigning roles to the individual nodes in your cluster: you can set one of your Safeguard for Privileged Sessions nodes to be the Central Management node and the rest of the nodes are managed from this central node.

Promote a Safeguard for Privileged Sessions node to be the Central Management node in a new cluster

You can build a cluster by promoting a Safeguard for Privileged Sessions node to the role of the Central Management node, and then join other nodes to your cluster.

To promote a node to be the Central Management node, complete the following steps:

1. Open a transaction.

   For details, see Open a transaction.

2. Create the Central Management node.
