32 Barracuda SSL VPN Administrator’s Guide
Policies and Resources
Once a Resource has been defined, access to it must be granted by attaching a Policy consisting of the
authorized users and groups. More than one Policy can be attached to any Resource, and each Policy
may be applied to many different Resources. However, because only Policies can be attached to
Resources, any user to whom you wish to allow access
must be in at least one of the attached Policies,
or in a group that is a member of an attached Policy.
Network Access Control
The
ACCESS CONTROL > NAC
page allows you to limit access to network resources based not just
by users, but also on a variety of other factors such as the time of day, the connecting system’s OS
(operating system) and browser, and even whether or not any anti-virus software is running on the
remote system. Exceptions to these limitations may be entered on the
ACCESS CONTROL > NAC
Exceptions
page.
Access Rights
The ssladmin account can designate other users and groups to manage specific aspects of the
Barracuda SSL VPN. To grant any Policy the rights to manage a particular Resource, System or their
own Personal configuration, go to the
ACCESS CONTROL > Access Rights
page and choose the
specific rights to grant. See also the Access Rights section on page 59 for more details.
