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.

URL
GET https://<IP-address-of-SPS>/api/configuration/management/universal_siem_forwarder
Cookies
Cookie name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For more information on authentication, see Authenticate to the SPS REST API.

NOTE: This session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).
Sample request

The following command lists the endpoints for SNMP configuration settings.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/management/universal_siem_forwarder
Response

            }
        ]
     }
Elements Type Description
body JSON object Top-level element
enabled boolean

Set to true and configure the other options as needed for your environment to forward session data from SPS to an external SIEM device.

prefix string

A prefix to make the data more readable.

The prefix is added to each JSON key. For example, if you use sps_ as a prefix, in the forwarded JSON message the {"protocol": "ssh"} key changes to {"sps_protocol": "ssh"}, which allows you to identify the forwarded data more easily.

Other formats ignore the Prefix option.

targets JSON object

Specifies the details of the target SIEM device.

format cef | json | json_cim

The format of the message sent to the SIEM. Use the following:

  • json_cim: if using Splunk.

  • cef: if using CEF-compatible SIEMs, for example, Microsoft Azure Sentinel.

  • json: for general use.

name string

The name of the SIEM forwarder policy.

protocol JSON object

Specifies connection details to the target SIEM device. For example:

"protocol": {
    "selection": "syslog",
    "value": {
        "address": {
            "selection": "ip",
            "value": "192.168.1.1"
        },
        "port": 5555,
        "tls": {
            "selection": "secure",
            "trusted_ca_list_ref": "1241814345d074efd1ded7"
        }
    }
}
Elements of protocol Type Description
selection string

Must be syslog

value JSON object

Contains the address of the SIEM and the TLS settings of the connection.

address JSON object

Contains the type and the value of the address. For example:

"address": {
    "selection": "ip",
    "value": "192.168.1.1"
},
"address": {
    "selection": "fqdn",
    "value": "my-siem.example.com"
},
selection string

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 IP address.

value string The address of the server, corresponding to the format set in the selection field.
port integer

The port number of the server.

tls JSON object

The security settings of the connection. For example:

tls": {
    "selection": "secure",
    "trusted_ca_list_ref": "1241814345d074efd1ded7"
}
"tls": {
    "selection": "disabled"
}
selection disabled | insecure | secure

  • disabled: Use an unencrypted connection. Since the data forwarded contains sensitive information, One Identity recommends to use TLS encryption between SPS and your SIEM.

  • insecure: Use TLS encryption, but do not validate the certificate of the SIEM.

  • secure: Use TLS encryption and validate the certificate of the SIEM. If you use this option, you must also set the trusted_ca_list_ref field.

trusted_ca_list_ref string

The key of the trusted CA list used to validate the certificate of the SIEM. This option is required if you set "selection": "secure". For details on creating trusted CA lists, see Trusted Certificate Authorities.
Configure universal SIEM forwarder
  2. Open a transaction.

    For more information, see Open a transaction.

  3. If you want to send the messages in an encrypted connection to the SIEM and also validate the certificate of the SIEM, upload the certificate of the CA that signed the certificate of the SIEM to a trusted CA list. For details on creating trusted CA lists, see Trusted Certificate Authorities.

  4. Create the JSON object that configures SPS to forward session data to your SIEM.

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

    {
    "enabled": true,
    "prefix": "myprefix",
    "targets": [
        {
            "format": "json_cim",
            "name": "siem_target",
            "protocol": {
                "selection": "syslog",
                "value": {
                    "address": {
                        "selection": "ip",
                        "value": "192.168.1.1"
                    },
                    "port": 5555,
                    "tls": {
                        "selection": "disabled"
                    }
                }
            }
        }
    ]
 }

Manage SPS clusters

When you have a set of two or more One Identity 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 SPS nodes to be the Central management node and the rest of the nodes are managed from this central node.

NOTE: All nodes in a cluster must run the same version of SPS.

NOTE: To configure the /api/cluster/ endpoint, your usergroup must have "read and write/perform" privileges assigned to the Basic Settings > Cluster management object. You can configure this on the Users & Access Control > Appliance Access page of SPS's web interface.

For details, see "Managing user rights and usergroups" in the Administration Guide.

Promote a SPS node to be the Central Management node in a new cluster

You can build a cluster by promoting a SPS 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 more information, see Open a transaction.

  2. Create the Central Management node.

    POST an empty request to the https://<IP-address-of-node-to-become-Central-Management-node>/api/cluster/promote endpoint.

    The following is a sample response received.

    For more information on the meta object, see Message format.

    {
    "body": {
        "address": "<IP-address-of-Central-Management-node>",
        "roles": [
            "central-management"
        ]
    },
    "meta": {
        "href": "/api/cluster/nodes/b35c54da-b556-4f91-ade5-d26283d68277",
        "parent": "/api/cluster/nodes",
        "remaining_seconds": 28800
    }
}
    Elements Type Description
    body Top-level element (JSON object) Contains the JSON object of the node.
    address string The IP address of the node.
    roles string The role of the node.
  3. Commit your changes.

    For more information, see Commit a transaction.

Join node(s) to the cluster

Once you have a Central Management SPS node in place, then you can join other nodes to your cluster.

To join nodes to your cluster, complete the following steps for each node that you want to join to the cluster:

  1. Open a transaction.

    For more information, see Open a transaction.

  2. Create a join request.

    POST the IP address of the Central Management node as a JSON object to the https://<IP-address-of-node-to-join-to-cluster>/api/cluster/join_request endpoint. The body of the POST request should be the following:

    {
    "central_management_address": "<IP-address-of-Central-Management-node>"
}

    For example:

    curl -X POST -H "Content-Type: application/json" --cookie cookies https://<IP-address-of-node-to-join-to-cluster>/api/cluster/join_request --data '{"central_management_address": "<IP-address-of-Central-Management-node>"}'

    The following is a sample response received.

    For more information on the meta object, see Message format.

    By default, no role is assigned to a non-management node, that is why the "roles" array is empty.

    {
    "body": {
        "address": "<IP-address-of-node-joined-to-cluster>",
        "node_id": "46f97a58-4028-467d-9a22-9cfe78ae3e1c",
        "psk": "Ler7HZDFmZCxnLLgHNRfZYfORhlZS99l9vEVr5UKtJEb1d4WeaHcBmQJLs4VDWIn",
        "roles": []
    },
    "meta": {
        "href": "/api/cluster/join_request",
        "parent": "/api/cluster",
        "remaining_seconds": 600
    }
}
    Elements Type Description
    body Top-level element (JSON object) Contains the JSON object of the node.
    address string The IP address of the node.
    node_id string A reference ID for the node.
    psk string The pre-shared key of the node used for authentication.
    roles string The role of the node.
  3. Join the node to the cluster.

    POST the "body" object of the response to the https://<IP-address-of-Central-Management-node>/api/cluster/nodes endpoint as a JSON object. The body of the POST request should be the following:

    {
    "address": "<IP-address-of-node-joined-to-cluster>",
    "node_id": "46f97a58-4028-467d-9a22-9cfe78ae3e1c",
    "psk": "Ler7HZDFmZCxnLLgHNRfZYfORhlZS99l9vEVr5UKtJEb1d4WeaHcBmQJLs4VDWIn",
    "roles": []
},

    For example:

    POST -H "Content-Type: application/json" --cookie cookies https://<IP-address-of-Central-Management-node>/api/cluster/nodes --data '{"address": "<IP-address-of-node-joined-to-cluster>", "node_id": "46f97a58-4028-467d-9a22-9cfe78ae3e1c", "psk": "Ler7HZDFmZCxnLLgHNRfZYfORhlZS99l9vEVr5UKtJEb1d4WeaHcBmQJLs4VDWIn","roles": []}'

    If the POST request is successful, the response includes:

    {
    "body": {
        "address": "<IP-address-of-node-joined-to-cluster>",
        "roles": []
    },
