5 Authentication and access management Instant messaging authentication Modules for authenticating users of an instant messaging service Two modules are called by the rules for authenticating users of an instant messaging service, the Authentication module and the File System Logging module. This section tells you how to configure the settings for these modules. Configure the authentication and logging modules Authentication for users of an instant messaging service and logging authentication activities involves the Authentication and the File System Logging modules. To configure settings for these modules: 1 Go to Policy | Rule Sets. 2 On the rule sets tree, go to the rule set that contains rules for authenticating users of an instant messaging service, for example, the IM Authentication rule set. 3 Select the nested rule set with the rules containing the settings you want to configure. For example, select the nested IM Authentication Server rule set, which contains the rule Authenticate clients against the user database, and in the rule criteria, select the User Database at IM Authentication Server settings. The Edit Settings window opens. 4 Configure these settings as needed. Then click OK to close the window. 5 Click Save Changes. For information on these settings, see Settings for the authentication and logging modules. For more information on the configuration procedure, see Configure the Authentication module and Implement an authentication method. Settings for the authentication and logging modules This section deals with the settings for the Authentication and File System Logging modules that are related to authentication of instant messaging users. These settings are implemented when you import the IM Authentication rule set from the rule set library. Authentication Server IM Settings for the Authentication module specifying the Authentication Server method to authenticate users of an instant messaging service Meaning and usage of these settings are the same as for the settings specifying the Authentication Server method to authenticate users under the HTTP and HTTPS protocol. For information on these settings, see Advanced Parameters. User Database at IM Authentication Server Settings for the Authentication module specifying the User Database method to authenticate users of an instant messaging service Meaning and usage of these settings are the same as for the settings specifying the User Database method to authenticate users under the HTTP or HTTPS protocol. For information on these settings, see User Database. 142 McAfee Web Gateway 7.1.5 Product Guide
Authentication and access management Cookie authentication 5 IM Logging Settings for the File System Logging module specifying the log file for logging activities related to instant messaging authentication and the way this log file is maintained Meaning and usage of these settings are the same as for other settings of the File System Logging Module. The settings include the default log file name. For the log file that entries on instant messaging authentication are written into, this name is im.log. For more information, see File System Logging Settings. Cookie authentication Users can be authenticated by cookies once they have successfully authenticated on the appliance. This section tells you how to configure cookie authentication. It describes a rule set and the settings of the module for this authentication. The rules in a rule set for cookie authentication say that a cookie is stored for a successfully authenticated user and what should be done when this user sends another request. Typically, the user does then not need to authenticate again. Note: The size of a cookie grows with the user information it contains. This can cause a problem for the browser you use to log on to the appliance. The Mozilla Firefox browser version 3.5 or higher does not support cookies bigger than 32 KB. So cookie authentication might not work for a user who is a member of many user groups. A cookie authentication rule set is not implemented after the initial setup of the appliance, but you can import one from the rule set library or create a rule set of your own. Like other authentication activities, cookie authentication is handled by the Authentication module. When the rule set for cookie authentication is imported from the library, settings for this module are also implemented. Cookie Authentication (rule set) This section describes the Cookie Authentication library rule set. The rules in this rule set control teh use of cookies for authenticating users who have already been authenticated successfully For general information on understanding and handling rules, see Rules and rule sets. i Library rule set — Cookie Authentication Criteria — Always Cycle — Requests (and IM) The following rule sets are nested in this rule set: • Cookie Authentication at HTTP(S) proxy • Set Cookie for Authenticated Clients • Authenticate Clients With Authentication Server • Cookie Authentication at Authentication Server • Authentication Server Request McAfee Web Gateway 7.1.5 Product Guide 143
