Cisco Cisco Web Security Appliance S670 Mode D'Emploi

 describes the advanced options you can configure for Outbound Malware Scanning Policy 

groups. 

Protocols

Choose whether or not to define policy group membership by the protocol used in 
the client request. Select the protocols to include.

“All others” means any protocol not listed above this option.

Note: When the HTTPS Proxy is enabled, only Decryption Policies apply to 
HTTPS transactions. You cannot define policy membership by the HTTPS protocol 
for Access, Routing, Outbound Malware Scanning, Data Security, or External DLP 
Policies. 

Proxy Ports

Choose whether or not to define policy group membership by the proxy port used 
to access the Web Proxy. Enter one or more port numbers in the Proxy Ports field. 
Separate multiple ports with commas.

For explicit forward connections, this is the port configured in the browser. For 
transparent connections, this is the same as the destination port. You might want to 
define policy group membership on the proxy port if you have one set of clients 
configured to explicitly forward requests on one port, and another set of clients 
configured to explicitly forward requests on a different port.

Cisco recommends defining policy group membership by the proxy port only when 
the appliance is deployed in explicit forward mode, or when clients explicitly 
forward requests to the appliance. If you define policy group membership by the 
proxy port when client requests are transparently redirected to the appliance, some 
requests might be denied.

Note: If the Identity associated with this policy group defines Identity membership 
by this advanced setting, the setting is not configurable at the non-Identity policy 
group level.

Subnets

Choose whether or not to define policy group membership by subnet or other 
addresses.

You can select to use the addresses that may be defined with the associated Identity, 
or you can enter specific addresses here. 

Note: If the Identity associated with this policy group defines its membership by 
addresses, then in this policy group you must enter addresses that are a subset of 
the addresses defined in the Identity. Adding addresses in the policy group further 
narrows down the list of transactions that match this policy group.

URL Categories

Choose whether or not to define policy group membership by URL categories. 
Select the user defined or predefined URL categories.

Note: If the Identity associated with this policy group defines Identity membership 
by this advanced setting, the setting is not configurable at the non-Identity policy 
group level.
