5 Authentication and access management Cookie authentication Redirect authenticated client back to the proxy Always — Redirect The rule redirects the request a user sent from a client. The action settings specify a redirect message that is sent to the user. Module for cookie authentication The rules for cookie authentication call the Authentication module to retrieve user information. This section tells you how to configure settings for this module. Configure the module for cookie authentication To configure settings for the module that handles cookie authentication: 1 Go to Policy | Rule Sets. 2 On the rule sets tree, go to the rule set that contains rules for cookie authentication, for example, the Cookie Authentication rule set. 3 Select the nested rule set with the rules containing the settings you want to configure. For example, select the nested Authenticate Clients with Authentication Server rule set, which contains the rule Redirect clients that have no valid cookie to the authentication server, and in the rule criteria, select the Local Cookie 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 cookie authentication module. For more information on the configuration procedure, see Configure the Authentication module and Implement an authentication method. Settings for the cookie authentication module This section deals with settings for the Authentication module that are related to cookie authentication. These settings are implemented when you import the Cookie Authentication rule set from the rule set library. Authentication Server - Cookie Check Settings for the Authentication module when it looks for cookies under the Authentication Server method Meaning and usage of these settings are the same as for the settings of the module when it uses the Authentication Server method for standard authentication. For information on these settings, see Advanced Parameters. Local Cookie Authentication Server Settings for the Authentication module when it looks for cookies Meaning and usage of these settings are the same as for the settings of the module when it uses the Authentication Server method for standard authentication. For information on these settings, see Advanced Parameters. 146 McAfee Web Gateway 7.1.5 Product Guide
Authentication and access management Quota management 5 User Database at Authentication Server Settings for the Authentication module specifying the User Database method for cookie authentication. Meaning and usage of these settings are the same as for the settings of the module when it uses the Authentication Server method for standard authentication. For more information, see User Database. Quota management You can guide the users of your network by imposing time and volume quotas and other restrictions on their web usage. This section explains these restrictions and tells you how to configure them. Restricting web usage through quota management Quotas for restricting the web usage of users can be imposed in several ways. Like other functions on the appliance, quotas are implemented by rules that use lists and call modules to retrieve relevant information. This section provides an overview of quota restrictions and the appliance functions that are related to them. Time quota By configuring time quotas, you can limit the time that users of your network are allowed to spend for web usage. Time quotas can be related to several parameters: • URL categories — When time quotas are related to URL categories, users are allowed only a limited time for accessing URLs that fall into particular categories, for example, Online Shopping. • IP addresses — When time quotas are related to IP addresses, users who send requests from particular IP addresses are allowed only a limited time for web usage. • User names — When time quotas are related to user names, users are allowed only a limited time for web usage. Users are identified by the user names they submitted for authentication on the appliance. Note: These parameters are used by the rules in the library rule set for time quotas. You can create rules of your own that use other parameters in relation to time quotas. The time that users spend on web usage is stored on the appliance. When the configured time quota has been exceeded for a user, a request that this user sends is blocked. A message is displayed to the user stating why the request was blocked. Users are identified by the user names they submitted for authentication. If no user name is sent with a request, web usage is recorded and blocked or allowed for the IP address of the client system that the request was sent from. Web usage can be limited to time spent per day, per week, or per month. Volume quota By configuring volume quotas, you can limit the volume of web objects, measured in GB and MB, that the users of your network are allowed to download from the web. Volume quotas can be related to several parameters: • URL categories — Users are allowed to download only a limited volume of web objects through URLs that fall into particular categories, for example, Streaming Media. • IP addresses — Users who send download requests from particular IP addresses are allowed only a limited volume. • User names — Users are allowed to download web objects only up to a limited volume. Users are identified by the user names they submitted for authentication on the appliance. McAfee Web Gateway 7.1.5 Product Guide 147
