Table 17-5
URL Category Filtering for Cisco IronPort Data Security Policies 
Action
Description
Use Global 
Setting
Uses the action for this category in the Global Policy Group. This is the default 
action for user defined policy groups.
Applies to user defined policy groups only.
When a custom URL category is excluded in the global Cisco IronPort Data Security 
Policy, then the default action for included custom URL categories in user defined 
Cisco IronPort Data Security Policies is Monitor instead of Use Global Settings. You 
cannot choose Use Global Settings when a custom URL category is excluded in the 
global Cisco IronPort Data Security Policy. 
Allow 
Always allows upload requests for web sites in this category. Applies to custom URL 
categories only.
Allowed requests bypass all further data security scanning and the request is 
evaluated against Access Policies.
Only use this setting for trusted web sites. You might want to use this setting for 
internal sites. 
Monitor
The Web Proxy neither allows nor blocks the request. Instead, it continues to 
evaluate the upload request against other policy group control settings, such as web 
reputation filtering.
Block
The Web Proxy denies transactions that match this setting.
