Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Control and protection against malicious or undesirable links is incorporated into the anti-spam, 
outbreak, content, and message filtering processes in the work queue. These controls: 

Increase the effectiveness of protection from malicious URLs in messages 

URL filtering is incorporated into Outbreak Filtering. This strengthened protection is useful even if 
your organization already has a Cisco Web Security Appliance or similar protection from web-based 
threats, because it blocks threats at the point of entry. 

You can also use content or message filters to take action based on the Web Based Reputation Score 
(WBRS) of URLs in messages. For example, you can rewrite URLs with neutral or unknown 
reputation to redirect them to the Cisco Web Security Proxy for click-time evaluation of their safety. 

Better identify spam 

The appliance uses the reputation and category of links in messages, in conjunction with other 
spam-identification algorithms, to help identify spam. For example, if a link in a message belongs 
to a marketing web site, the message is more likely to be a marketing message. 

Support enforcement of corporate acceptable use policies 

The category of URLs (for example, Adult Content or Illegal Activities) can be used in conjunction 
with content and message filters to enforce corporate acceptable use policies. 

Allow you to identify users in your organization who most frequently clicked a URL in a message 
that has been rewritten for protection, as well as links that have most frequently been clicked.
