Manage the SPS license

You can display information about the currently used SPS license from the https://<IP-address-of-SPS>/api/configuration/management/license endpoint.

 Caution:

Accessing the One Identity Safeguard for Privileged Sessions (SPS) host directly using SSH is not recommended or supported, except for troubleshooting purposes. In such case, the One Identity Support Team will give you exact instructions on what to do to solve the problem.

For security reasons, disable SSH access to SPS when it is not needed. For details, see "Enabling SSH access to the One Identity Safeguard for Privileged Sessions (SPS) host" in the Administration Guide.

The following encryption algorithms are configured on the local SSH service of SPS:

  • Key exchange (KEX) algorithms:

    diffie-hellman-group-exchange-sha256

  • Ciphers:

    aes256-ctr,aes128-ctr

  • Message authentication codes:

    hmac-sha2-512,hmac-sha2-256

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.

host JSON object

Contains the hostname or the IPv4 address of the Splunk server.

"host":
    { "selection": "fqdn", "value": "splunk.example.com" },
"host":
    { "selection": "ip", "value": "192.168.1.1" },
selection fqdn | ip

Defines the address type (IP or domain name). Possible values are:

  • fqdn: The server address is provided as a fully qualified domain name.

  • ip: The server address is provided as an IPv4 address.

value string

The address of the server.

port integer

The port number where your Splunk HTTP Event Collector is accepting connections. By default, Splunk uses port 8088.

ssl JSON object

Determines if encryption is used between SPS and Splunk.

selection string

Determines if encryption is used between SPS and Splunk. Possible values:

  • disabled: Use this option if your Splunk HTTP Event Collector accepts only unencrypted HTTP connections.

    Since the data forwarded to Splunk contains sensitive information, One Identity recommends to use HTTPS encryption between SPS and Splunk.

    "ssl": { "selection": "disabled" },

  • insecure: Use HTTPS encryption between SPS and Splunk.

    "ssl": { "selection": "insecure" },

  • secure: Use HTTPS encryption between SPS and Splunk and also verify the identity of the Splunk server. If you use this option, you must include the certificate of the Splunk server, or the certificate of the CA that issued the certificate of the Splunk server in the certificate option.

    "ssl":
    { "certificate": "-----BEGIN CERTIFICATE-----\nMIIFPzCCAyegA\n....\nr8lDCPoq\n0wgJ\n-----END CERTIFICATE-----\n",
    "selection": "secure"
    },
token string

The HTTP Event Collector authentication token you have generated for SPS.
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 more information, 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" in the Administration Guide.

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.

Prerequisites and restrictions

  • SPS version 5 F9 or later

  • Splunk version 6.5 or later

  • The CEF format is supported on all currently supported versions of ArcSight ESM, IBM QRadar and Microsoft Azure Sentinel.

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