Cisco Cisco Web Security Appliance S360 User Guide

You can configure the Web Security appliance to filter adult content from some web searches and 
websites. To enforce safe search and site content ratings, the AVC engine takes advantage of the safe 
mode feature implemented at a particular website by rewriting URLs and/or web cookies to force the 
safety mode to be on. 

The following features filter adult content: 

Any Access Policy that has either the safe search or site content ratings feature enabled is considered a 
safe browsing Access Policy.

Choose Web Security Manager > Access Policies.

Click the link under the URL Categories column for an Access Policy group or the Global Policy Group.

When editing a user-defined Access Policy, choose Define Content Filtering Custom Settings in the 
Content Filtering section.

Click the Enable Safe Search check box to enable the safe search feature.

Choose whether to block users from search engines that are not currently supported by the Web Security 
appliance safe search feature.

Click the Enable Site Content Rating check box to enable the site content ratings feature.

Choose whether to block all adult content from the supported content ratings websites or to display the 
end-user URL filtering warning page.

When the URL of one of the supported search engines or supported content ratings websites is included 
in a custom URL category with the Allow action applied, no search results are blocked and all content 
is visible.

Enforce safe searches

You can configure the Web Security appliance so that outgoing search 
requests appear to search engines as safe search requests. This can 
prevent users from bypassing acceptable use policies using search 
engines.

Enforce site content ratings

Some content sharing sites allow users to restrict their own access to the 
adult content on these sites by either enforcing their own safe search 
feature or blocking access to adult content, or both. This classification 
feature is commonly called content ratings.
