HTTP channels
The available HTTP channel types and their functionalities are described below. For details on configuring channel policies, see Channel policy.
http |
No |
http: Enables access to the server. This channel must be enabled for HTTP connections to work. |
websocket |
No |
websocket: Enables all WebSocket traffic. If the WebSocket channel type is not allowed, HTTP requests trying the WebSocket upgrade are rejected.
WebSocket/VNC audit trails: You can replay audit trails of a WebSocket connection in your browser or using the Safeguard Desktop Player application only if it contains Virtual Network Computing (VNC) traffic. For all other WebSocket connections, export the audit trail as a PCAP file and replay it using the Safeguard Desktop Player application. |
HTTP 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 SPS.
URL
GET https://<IP-address-of-SPS>/api/configuration/http/authentication_policies
Cookies
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 HTTP authentication policies.
curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/http/authentication_policies
The following command retrieves the properties of a specific policy.
curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/http/authentication_policies<object-id>
