Policy Group Membership

Policy group control settings. Define how users in the group can use the Internet. The control
settings you can define depend on the policy type. For example, for Routing Policies, you define
from which proxy group to fetch the content, and for Access Policies, you can use the Web Security
appliance features, such as Web Reputation, anti-malware scanning, and more to determine whether
or not to allow the client request.

Policy Group Membership
All policy groups define which transactions apply to them. When a client sends a request to a server, the
Web Proxy receives the request, evaluates it, and determines to which policy group it belongs. The Web
Proxy applies the configured policy control settings to a client request based on the client request’s
policy group membership.

Transactions belong to a policy group for each type of policy that is enabled. If a policy type has no user
defined policy groups, then each transaction belongs to the global policy group for that policy type.

Policy group membership for a Routing, Decryption, Access, Data Security, and External DLP Policies
is based on an Identity and optional additional criteria. That means that the Web Proxy evaluates Identity
groups before the other policy types. The Web Security appliance allows you to define some membership
criteria at either the Identity level or the non-Identity policy level. For more information, see

Suppose you define an Identity by subnet 10.1.1.0/24 and then create an Access Policy using that
Identity. The Access Policy membership applies to all IP addresses specified in the Identity by default.
You can then choose to configure the Access Policy membership so that it applies to a subset of the
addresses defined in the Identity, such as addresses 10.1.1.0-15.

Authenticating Users versus Authorizing Users
The Web Security appliance separates where it authenticates users from where it authorizes users.
