Configuring Resources for a User Group
98 Firebox SSL VPN Gateway
• Kiosk resources that define how the user can log on and which file shares and applications are
accessible to the user when logged on. If the user is allowed to use the Firefox Web browser in
kiosk mode, the Web address the user is allowed to use is also defined.
• End point resources and policies that define the required and optional parameters that must be
on the user’s computer when logging on.
If a user belongs to more than one group, group policies are applied to the user based on the group pri-
orities set on the
Group Priority tab, as described in “Setting the Priority of Groups”.
Adding Users to Multiple Groups
When a user is a member of multiple groups, some group settings are unioned together. These settings
are:
• Network Resources
• Application Policies
• Kiosk Resources
• End Point Policies
Settings that are not unioned are based on group priority. These include:
• Authenticating after network interruption or on system resume
• Enabling single sign-on
• Running logon scripts
• Session time-out
• Split DNS
• Portal page authentication
Exceptions to the unionized settings are:
• Deny applications without policies. If any of the groups that a user is a member of has the Deny
applications without policies check box selected, the user inherits that setting.
• IP pooling. Users assume the IP address from the highest priority group that has IP pools enabled.
• Inherit Default group settings. If any of the groups that a user is a part of has the
Inherit
properties from the Default Group check box selected, the user inherits that setting.
Allowing and denying network resources and application policies
By default, all network resources and application policies are allowed. When you deny one resource
group, all other resource groups are denied automatically and the network access for the user group is
controlled only through its ACL.
The Firebox SSL VPN Gateway interprets allow or deny as follows:
• The Firebox SSL VPN Gateway denies access to any network resource or application policy that is
not explicitly allowed. Thus, if you want to provide a particular user group with access to only one
resource group, you allow access only to that resource group.
• Deny rules take precedence over allow rules. This enables you to allow access to a range of
resources and to also deny access to selected resources within that range. For example, you
might want to allow a group access to a resource group that includes 10.20.10.0/24, but need to
deny that user group access to 10.20.10.30. To handle this, you create a resource group that
includes 10.20.10.30. Access to that resource is denied unless you specifically allow it.
