One Identity Safeguard for Privileged Sessions 6.9.3 - REST API Reference Guide

Agent: Forwards the SSH authentication agent from the client to the server.

X11 Forward: Forwards the graphical X-server session from the server to the client. List the address of the client in the networks field to permit X11-forwarding only to the specified clients. Specify IP addresses or networks (in IP address/Prefix format). For example:

"networks": [
  {
    "selection": "address",
    "value": "192.168.1.1"
  },
  {
    "selection": "address",
    "value": "192.168.1.2"
  }
                        
NOTE: Certain client applications send the Target address as a hostname, while others as an IP address. If you are using a mix of different client applications, you might have to duplicate the channel rules and create IP-address and hostname versions of the same rule.
Channel-specific access control rules:
networks (list): To X11-forwarding only to specific clients, list the IP addresses or networks of the clients in this field. Leave it empty to permit access to every client. For details, see Limiting addresses in port forwarding.

Local Forward: Forwards traffic arriving to a local port of the client to a remote host. To enable forwarding only between selected hosts, use the local_forwards field. If the local_forwards field is empty, local forwarding is enabled without restriction, the client may forward any traffic to the remote host.

For example:

"local_forwards": [
  {
    "host_address": {
      "selection": "address",
      "value": "192.168.100.1"
    },
    "host_port": 5555,
    "originator_address": {
      "selection": "address",
      "value": "192.168.1.1"
    }
  }
                        
Channel-specific access control rules:
local_forwards (list): To permit local forwarding only to specific addresses, list the addresses in this field. Leave it empty to enable without restriction. In this case the client may forward any traffic to the remote host.
Enter the source of the forwarded traffic into the originator_address field, the target of the traffic into the host_address field. Specify IP addresses or networks (in IP address/Prefix format). These parameters are the end-points of the forwarded traffic (that is, the local host that sends data to the remote host), and not the SSH server or the client. For example, to enable forwarding from the 192.168.20.20 host to the remote host 192.168.50.50, enter 192.168.20.20 into the originator_address, and 192.168.50.50 into the host_address field. For details, see Limiting addresses in port forwarding.

Remote Forward: Forwards traffic arriving a remote port of the server to the client. To enable forwarding only between selected hosts, enter their IP addresses into the remote_forwards field. If the remote_forwards field is empty, remote forwarding is enabled without restriction, the SSH server may forward any traffic to the client.

For example:

"remote_forwards": [
  {
    "connected_address": {
      "selection": "address",
      "value": "192.168.100.1"
    },
    "connected_port": 5555,
    "originator_address": {
      "selection": "address",
      "value": "192.168.1.1"
    }
  }
                        
Channel-specific access control rules:
remote_forwards (list): To permit only specific forwardins, list the permitted addresses in this field. Leave it empty to permit forwarding without restrictions.
Enter the source of the forwarded traffic into the originator_address, the target of the traffic into the connected_address field. Specify IP addresses or networks (in IP address/Prefix format). These parameters are the end-points of the forwarded traffic (that is, the remote host that sends data to the client), and not the SSH server. For example, to enable forwarding from the 192.168.20.20 remote host to the client 192.168.50.50, enter 192.168.20.20 into the originator_address, and 192.168.50.50 into the connected_address field. For details, see Limiting addresses in port forwarding.

Session Exec: Execute a remote command (for example rsync) without opening a session shell. List the permitted command in the execs field. You can use regular expressions to specify the commands. This field can contain only letters (a-z, A-Z), numbers (0-9), and the following special characters ({}()*?\\|[]).

Channel-specific access control rules:

• execs (list): List the permitted command in the execs field. Regular expressions may be used to specify the commands.

For example:

"execs": [
  "top",
  "ls"
                    

Session Exec SCP: Transfers files using the Secure Copy (SCP) protocol.

Channel-specific actions:

• log_transfer_to_db (list): (true|false): Make the list of file operations available in the Search > File operations column of the SPS web interface

• log_transfer_to_syslog (list): (true|false): Send the file operations into the system log

For example:

"actions": {
  "audit": false,
  "four_eyes": false,
  "ids": false,
  "log_transfer_to_db": true,
  "log_transfer_to_syslog": true
}

Session Subsystem: Use a subsystem. Enter the name of the permitted subsystem into the subsystems field.

Channel-specific access control rules:

• subsystems (list): List the permitted subsystems in this field.

For example:

"execs": [
  "top",
  "ls"
                    

Session SFTP: Transfers files using the Secure File Transfer Protocol (SFTP).

Channel-specific actions:

• log_transfer_to_db (list): (true|false): Make the list of file operations available in the Search > File operations column of the SPS web interface

• log_transfer_to_syslog (list): (true|false): Send the file operations into the system log

For example:

"actions": {
  "audit": false,
  "four_eyes": false,
  "ids": false,
  "log_transfer_to_db": true,
  "log_transfer_to_syslog": true
}

Specifies the type of the address. Possible values: address or network

Defines the authentication method for client-side gateway authentication. Possible values are:

• none

  Disables client-side gateway authentication.

• ldap

  Uses the LDAP server selected for the connection policy. LDAP servers can be configured in the /api/configuration/policies/ldap_servers endpoint).

  To use this option, you must also configure the password and public_key elements.

• local

  Uses the local user database configured in the /api/configuration/policies/user_databases/ endpoint.

  To use this option, you must also configure the password, public_key, and user_database elements.

• radius

  Uses one or more Radius servers for authentication.

  To use this option, you must also configure the authentication_protocol and servers elements.

Set it to true to enable public key-based client-side authentication.

References the key of the local user database. You can configure local user databases at the /api/configuration/policies/user_databases/ endpoint.

To modify or add a local user database, use the value of the returned key as the value of the user_database element, and remove any child elements (including the key).

Defines the properties of the RADIUS servers used for client-side authentication.

A valid list item consists of the address, port and shared_secret elements.

Required child of the address element. Possible values are:

• ip

  The value element contains the IP of the RADIUS server.

• fqdn

  The value element contains the FQDN of the RADIUS server.

References the key of the shared secret for the RADIUS server. You can configure shared secrets at the /api/configuration/passwords/ endpoint.

To modify or add a shared secret, use the value of the returned key as the value of the shared_secret element, and remove any child elements (including the key).

Alternatively, you can include the new password as plain text.

"shared_secret": {
    "plain": "<new-password>"
}

Authentication based using Kerberos.

Set it to true to enable Kerberos-based client-side authentication. If required, you can select other gateway authentication methods in addition to Kerberos, and also authentication backends and related to the selected gateway authentication methods.

To use Kerberos authentication on the target server, you must use Kerberos authentication both on the SPS gateway and on the target server (in relayed_methods).

Authentication based on username and password.

Set it to true to enable password-based client-side authentication.

Authentication based using Kerberos.

Set it to true to enable Kerberos-based client-side authentication. If required, you can select other gateway authentication methods in addition to Kerberos, and also authentication backends and related to the selected gateway authentication methods.

To use Kerberos authentication on the target server, you must use Kerberos authentication both on the SPS gateway and on the target server (in relayed_methods).

Authentication based on exchanging messages between the user and the server. This method includes authentication schemes like S/Key or TIS authentication. Depending on the configuration of the SSH server, might have to be used together with password-based authentication.

Set to true to enable interactive authentication on the remote server.

Authentication based on username and password.

Set to true to enable password-based authentication on the remote server.

Authentication based on public-private encryption keypairs.

Use the selection child element to disable or configure authentication using public-private keypairs on the remote server.

Configures authenticaton on the remote server using public-private keypairs. The following values are possible:

• disabled

  Disables the authentication method.

• publish_to_ldap

  SPS generates a keypair, and uses this keypair in the server-side connection. The public key of this keypair is also uploaded to the LDAP database set in the LDAP Server of the connection policy. That way the server can authenticate the client to the generated public key stored under the user's username in the LDAP database. You can configure LDAP servers using the /api/configuration/policies/ldap_servers endpoint, and connection policies using the /api/configuration/ssh/connections endpoint.

• fix

  Uses a private key in the server-side connection.

  You have to use the private_key element to reference the private key.

• agent

  Allow the client to use agent-forwarding, and use its own keypair on the server-side.

  If this option is used, SPS requests the client to use its SSH agent to authenticate on the target server. Therefore, you must configure your clients to enable agent forwarding, otherwise authentication will fail. For details on enabling agent forwarding in your SSH application, see the documentation of the application.

Configures local or remote timestamping.

• Set local to use SPS for timestamping.

• Set remote to configure a remote timestamping server.

Required for remote timestamping.

The URL of the timestamping server. Note that HTTPS and password-protected connections are not supported.

Required for remote timestamping.

Set to true to configure the Object Identifier of the timestamping policy on the timestamping remote server.

Required if the oid is enabled.

The Object Identifier of the timestamping policy on the remote timestamping server.

Before establishing the server-side connection, SPS can evaluate the connection and channel policies to determine if the connection might be permitted at all. The server-side connection is established only if the evaluated policies permit the client to access the server.

To enable this function, set the parameter to true.

When this option is enabled, SPS rejects connections that use unrealistic parameters (for example, terminals of thousand by thousand characters) and port-forwarding connections where the address in the port-forwarding request and the channel-opening request does not match. Note that this can interfere with certain client or server applications.

Strict mode is allowed by default. To turn it off, set the parameter to false.

• true: If no user activity is detected, it terminates the session after the configured time has passed since the last user activity.
• false: No user inactivity timeout.

Only if enabled is true

The value of user activity timeout. Must be greater than or equal to the value of timeout
