The following describes how to configure four-eyes authorization.

To require four-eyes authorization for a connection

1. Navigate to the Connections page of the traffic (for example to SSH Control > Connections), and select the connection policy to modify.

2. Figure 251: <Protocol name> Control > Connections > Access Control — Configuring four-eyes authorization

   

   Navigate to Access Control and click .

3. Enter the name of the usergroup whose members are permitted to authorize the sessions of the connection policy into the Authorizer Group field. This group must exist on the AAA > Group Management page. For details on creating and managing usergroups, see Managing user rights and usergroups.

   Caution: Usernames, the names of user lists, and the names of usergroups are case sensitive.

4. By default, the authorizer can authorize any session of the connection policy.

   If the authorizer is permitted to authorize only the sessions of a certain usergroup, select Client user is > Member of, and enter the name of the userlist whose sessions the authorizer can authorize. If you use four-eyes authorization without gateway authentication, you can specify an LDAP group instead of a userlist.

   Caution: Usernames, the names of user lists, and the names of usergroups are case sensitive.

   Caution: When using both gateway authentication and four-eyes authorization in a Connection Policy, specify the usergroup of the gateway username. The specified group must be a local or LDAP group.

5. Set the permissions of the usergroup set in the Authorizer Group field.

   • If the Authorizer group can authorize (that is, enable) and audit (that is, monitor in real-time and download the audit trails) the sessions, select Permission > Search&Authorize.

   • If the Authorizer group can only authorize (that is, enable) the sessions, select Permission > Authorize.

     NOTE: This option is not valid for HTTP connections.

   • If the Authorizer group can only audit (that is, monitor in real-time and download the audit trails) the sessions, select Permission > Search.

   NOTE: If the Client user is > Member of field is set, the auditor can only monitor the sessions of the specified usergroup. However, if Client user is > Member of field is set, the Auditor cannot access the Search page. To avoid this problem, add another Access Control rule for the Authorizer Group without setting the Client user isfield. The admin user of One Identity Safeguard for Privileged Sessions (SPS) can audit and authorize every connection.

6. To ensure that the client and the authorizer use different IP addresses and thus prevent self-authorization, enable Require different IP. If this is enabled, and the client and the authorizer do not have different IP addresses, it disables all actions for the connection and the four-eyes authorization, until they have different IP addresses.

7. To ensure that the client and the authorizer use different usernames and thus prevent self-authorization, enable Require different Username. If this is enabled, and the client and the authorizer do not have different usernames, it disables all actions for the connection and the four-eyes authorization, until they have different usernames.

8. Repeat steps 2-6 to add other authorizers or usergroups if needed.

9. Click .

10. Navigate to the Channel Policies page of the traffic (for example, to SSH Control > Channel Policies), and select the channel policy used in the connection.

    Figure 252: <Protocol name> Control > Channel Policies — Configuring four-eyes authorization in the channel policy

    

11. Enable the Four-eyes option for the channels which should be accessed only using four-eyes authorization.

    NOTE: If a connection uses secondary channels that require four-eyes authorization — for example, a Remote Desktop connection allows a Drawing channel but requires four-eyes authorization for a Disk redirection channel — the connection is locked until the authorizer accepts the channel on the Four-Eyes page of SPS, or the four-eyes request times out. During this time, the client application can become nonresponsive, for example, display the graphical desktop but not react to mouse clicks.

    NOTE: In Citrix ICA connections, four-eyes authorization is required before the user logs in to the destination server. To request four-eyes authorization only after the log in, when the server-side username is already known, select the Perform 4 eyes after user login option.

12. Click . After that, users accessing connections using the modified channel policy must be authorized as described in Performing four-eyes authorization on One Identity Safeguard for Privileged Sessions (SPS).

13. (Optional) If you want to provide a limited SPS web interface to your users that can be used only for gateway authentication and 4-eyes authorization, set up a dedicated user-only web login address. For details, see Configuring user and administrator login addresses.
