Option

Description

L4 Traffic Monitor

Choose whether the Layer-4 Traffic Monitor should monitor or block 
layer 4 traffic.
The L4 Traffic Monitor detects rogue traffic across all network ports 
and stops malware attempts to bypass port 80.
You might choose to monitor traffic when you evaluate the Web 
Security appliance, and block traffic when you purchase and use the 
appliance.
For more information, see “Configuring the L4 Traffic Monitor” on 
page 389.

Acceptable Use 
Controls

Choose whether or not to enable Acceptable Use Controls so you can 
choose a URL filtering engine, either Cisco IronPort Web Usage 
Controls or IronPort URL Filters.
URL filtering engines allow you to control user access based on the 
category of a URL in a request. Enable this option when you want to 
restrict users from accessing particular types of websites. 
Note: If you enable Cisco IronPort Web Usage Controls, the Dynamic 
Content Analysis engine is enabled by default. You can edit this setting 
after system setup.
For more information, see “URL Filters” on page 267.
