These events are described below. In this scenario, the user is authenticated using SafeWord PremierAccess, which implements a challenge-response authentication process. (Note that the process is different for other authentication methods.) 1 client PC or workstation NT PDC OR BDC LDAP SERVER RADIUS SERVER DEFENDER SEC.

Users, groups, and authentication Configuring authentication services Users, groups, and authentication 1. A user tries to make a network connection via Telnet or FTP. 2. The Sidewinder G2 checks the active rules to determine whether the connection between the source and destination addresses is allowed and to determine which warder to use. 3. If the connection is allowed, the proxy contacts the appropriate warder in the Sidewinder G2. 4. The warder passes the log in request to the appropriate authentication server. The server checks the data base to verify the user’s log in name is registered and then generates a log in prompt. 5. The log in challenge is sent to the user. Using client software or a hardware authenticator, the user types in the proper response to the prompt. 6. The Sidewinder G2 sends the response to the authentication server. The authentication server checks the response and informs the Sidewinder G2 to either accept or reject the log in request. As a Sidewinder G2 administrator, you are responsible for configuring the Sidewinder G2 to work with the desired authentication server. The first step is identifying the users that will need authentication services on the Sidewinder G2. You can set up authentication on a user-byuser basis or create user groups. A user group is a mechanism that allows you to identify multiple users by a single name, making it easier to configure authentication requirements for your network. Note: The procedures to add users to the user database and set up user groups are described in Chapter 5. After defining and creating the appropriate user groups for your site, you need to configure the authentication method(s) that your site will use. The following section describes what needs to be done to configure the Sidewinder G2 for authenticating users or administrators. To configure authentication services for the Sidewinder G2, start the Admin Console and select Services Configuration -> Authentication. The Authentication Configuration window appears. Note: You must configure an authentication method before it can be enabled. Setting Up Authentication 9-11
