SSH authentication policies

Lists the configured authentication methods that can be used in a connection. Each connection policy uses an authentication policy to determine how the client can authenticate to the target server. Separate authentication methods can be used on the client and the server-side of the connection.

URL
GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/configuration/ssh/authentication_policies
Headers
Header 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 details on authentication, see Authenticate to the Safeguard for Privileged Sessions REST API.

Note that this session ID refers to the connection between the REST client and the Safeguard for Privileged Sessions REST API. It is not related to the sessions that Safeguard for Privileged Sessions records (and which also have a session ID, but in a different format).

    Safeguard for Privileged Sessions 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.

Element Type Description
key string Top level element, contains the ID of the policy.
body Top level element (string) The elements of the SSH settings policy.
client_side_algorithms Top level element (list) Lists the permitted client-side encryption parameters.
cipher list Lists the permitted client-side cipher algorithms.
compression list Lists the permitted client-side compression algorithms.
kex list Lists the permitted client-side KEX algorithms.
mac list Lists the permitted client-side MAC algorithms.
greeting string Greeting message for the connection.
name string Name of the SSH settings policy.
preconnect_channel_check boolean

Before establishing the server-side connection, Safeguard for Privileged Sessions 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.

server_side_algorithms Top level element (list) Lists the permitted server-side encryption parameters.
cipher list Lists the permitted server-side cipher algorithms.
compression list Lists the permitted server-side compression algorithms.
kex list Lists the permitted server-side KEX algorithms.
mac list Lists the permitted server-side MAC algorithms.
software_version string Specifies additional text to append to the SSH protocol banner sent by the server upon connection.
strict_mode boolean

When this option is enabled, Safeguard for Privileged Sessions 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.

timeout int Connection timeout, in seconds. Note that the Safeguard for Privileged Sessions web UI displays the same value in milliseconds.
userauth_banner string You can display a banner message to the clients before authentication (as specified in RFC 4252 — The Secure Shell (SSH) Authentication Protocol). You can use this banner to inform the users that the connection is audited.
Status and error codes

The following table lists the typical status and error codes for this request. For a complete list of error codes, see Using the Safeguard for Privileged Sessions REST API.

SSH host keys and certificates

Safeguard for Privileged Sessions stores the host keys and X.509 certificates of the trusted servers. When a client tries to connect to a server, Safeguard for Privileged Sessions verifies the host key or the certificate of the server, and allows connections only to the servers that have their keys available on Safeguard for Privileged Sessions (unless the SSH Connection Policy is configured differently).

URL
GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys
Headers
Header 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 details on authentication, see Authenticate to the Safeguard for Privileged Sessions REST API.

Note that this session ID refers to the connection between the REST client and the Safeguard for Privileged Sessions REST API. It is not related to the sessions that Safeguard for Privileged Sessions records (and which also have a session ID, but in a different format).

Search and filter host keys

To list only specific host keys, you can use the following filters.

  • List every host key and certificate:

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys

  • List host keys of a specific type:

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys?type=<type-to-list>

    Possible values: ssh-rsa, ssh-dss, x509v3-sign-rsa, x509v3-sign-dss. For example:

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys?type=ssh-rsa

  • List host keys for a specific port number:

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys?port=<port-number-to-list>

  • List host keys for a specific host address (IPv4 or IPv6):

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys?address=<host-address>

  • For a complex filter, separate the parameters with an ampersand (&) character, for example:

    GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys?port=<port-number-to-list>&type=<type-to-list>

The response to such requests is a JSON object, where the items list includes the IDs of the selected host keys (or an empty list). For example, filtering for ssh-dss keys could return a similar list:

{
  "meta": {
    "href": "/api/ssh-host-keys",
    "parent": "/api"
  },
  "items": [
    {
      "key": "ssh-dss-10.110.0.1:22",
      "meta": {"href": "/api/ssh-host-keys/ssh-dss-10.110.0.1:22"}
    },
    {
      "key": "ssh-dss-10.110.0.2:2222",
      "meta": {"href": "/api/ssh-host-keys/ssh-dss-10.110.0.2:2222"}
    }
  ]
}
Add new host key

To upload a new host key or certificate, you have to POST the host key and other data as a JSON object to the https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys endpoint. For details, see Using the Safeguard for Privileged Sessions REST API. The body of the POST request must contain a JSON object with the parameters listed in SSH host keys and certificates. If the POST request is successful, the response includes an ID for the host key in the following format: <type-of-the-key>-<host-address>:<host-port>. For example:

{
  "address": "10.110.0.1",
  "port": 22,
  "type": {
    "selection": "ssh-rsa",
    "value": "AAAAB3NzaC1yc2EAAAAD...zvMwgc=="
  }
}

Note that for IPv6 addresses, Safeguard for Privileged Sessions will automatically convert the address to its canonical format.

Delete host key

To delete a host key or certificate, you have to DELETE https://<IP-address-of-Safeguard for Privileged Sessions>/api/ssh-host-keys/<ID-of-the-host-key> endpoint. For details, see Using the Safeguard for Privileged Sessions REST API. If the DELETE request is successful, the response includes only the meta object, for example:

{
    "meta": {
        "href": "/api/ssh-host-keys/ssh-rsa-10.10.20.35:22",
        "parent": "/api/ssh-host-keys"
    }
}

You must commit your changes to actually delete the object from Safeguard for Privileged Sessions.
