The following sections describe configuration settings available only for the HTTP protocol. Use the following policies to control who, when, and how can access the HTTP connection. For details on configuring Channel Policies, see Creating and editing channel policies. For a list of supported client applications, see Supported protocols and client applications.
Auditing HTTP and HTTPS connections is possible in both transparent and non-transparent modes. SPS can also be used as an HTTP/HTTPS proxy to simplify client configuration and integration into your network environment, or it can forward HTTP traffic, behaving as a HTTP tunnel.
-
Channel Policy: The channel policy determines which HTTP channels can be used in the connection, and whether they are audited or not. The different channels may be available only under certain restrictions, as set in the channel policy. For details on configuring these options, see Creating and editing channel policies.
-
HTTP connections: For details, see Setting up HTTP connections.
-
HTTP sessions: HTTP settings determine the parameters of the connection on the protocol level, including timeout value, and so on. For details, see Session-handling in HTTP.

The available HTTP channel types and their functionalities are described below. For details on configuring Channel Policies, see Creating and editing channel policies. For a list of supported client applications, see Supported protocols and client applications.
-
HTTP: Enables you to use the HTTP protocol. This channel must be enabled for HTTP to work.
The available channel policy options are the following: From, Target, Time policy, Record audit trail, and Remote groups. Note that the Remote groups option is used only if the user performs inband authentication using one of the supported HTTP authentication methods (see Authentication in HTTP and HTTPS). To retrieve the groups of an authenticated user from an LDAP database, you must also set an LDAP Server in the Connection Policy (for HTTP/HTTPS connections, One Identity Safeguard for Privileged Sessions (SPS) uses this server only to retrieve the group membership of authenticated users, you cannot authenticate the users to LDAP from SPS). For details on configuring these options, see Creating and editing channel policies.
When setting Target, note the following:
-
If the connection uses DNAT (NAT destination address), the target address of the original client will be compared to the Target parameter of the Channel policy, that is not necessarily equivalent with the server's address.
-
If the connection is redirected to a Fix address, the redirected address will be compared to the Target parameter of the Channel policy.
-
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.
When configuring HTTP or SSH connections, avoid using the IP address configured for administrator or user login on One Identity Safeguard for Privileged Sessions (SPS) .
The current version of SPS does not support the following features that are available for other protocols:
Forwarding HTTP connections to an HTTP proxy is not supported. If your clients use an HTTP proxy to access the target servers, place SPS behind the proxy: Clients - HTTP Proxy - SPS.

Caution:
The Clients - SPS - HTTP Proxy scenario is NOT supported. |
For the audited HTTP and HTTPS connections, One Identity Safeguard for Privileged Sessions (SPS) supports the following inband authentication methods for the HTTP protocol. These authentication methods are automatically supported for every Connection policy, without further configuration.
-
Basic Access Authentication (according to RFC2617)
-
The NTLM authentication method commonly used by Microsoft browsers, proxies, and servers
SPS records the username used in the authentication process into the Username and Remote username fields of the connection database.
For authenticated sessions, SPS can perform group-based user authorization that allows you to finetune access to your servers and services: you can set the required group membership in the Channel policy of the HTTP connection. Note that group-based authorization in HTTP works only for authenticated sessions (for HTTP/HTTPS connections, SPS uses this server only to retrieve the group membership of authenticated users, you cannot authenticate the users to LDAP from SPS). If a username is not available for the session, SPS will permit the connection even if the Remote groups field is set.
SPS does not store failed HTTP authentication attempts in the connection database. This means that the Verdict field of the Search page will never contain CONN-AUTH-FAIL values for HTTP connections.
Note that authentication also affects the way SPS handles HTTP sessions. For details, see Session-handling in HTTP.
