What’s New in This Release
The AVC engine is an acceptable use policy component that inspects web traffic
to gain deeper understanding and control of web traffic used for applications.
Application control gives you more granular control over web traffic than just
URL filtering. For example, you can block streaming media from sports sites, but
not news sites.

New Feature: Safe Search and Site Content Rating Enforcement
AsyncOS for Web 7.0 uses the AVC engine to filter adult content from some web
searches and websites. You might want to do this to allow access to these sites,
such as google.com and youtube.com, while still restricting potentially unsafe
content from reaching users.
searches and websites. You might want to do this to allow access to these sites,
such as google.com and youtube.com, while still restricting potentially unsafe
content from reaching users.
AsyncOS for Web offers the following features to filter adult content:
•
Enforce safe searches. Most search engines allow the safe search feature to
be enabled and disabled by end users. You can configure the Web Security
appliance so that outgoing search requests appear to search engines as safe
search requests. This gives the control to an administrator on the network
instead of the end user. You might want to do this to prevent users from
bypassing acceptable use policies using search engines.

•
Enforce site content ratings. Many content sharing sites that serve
user-generated photos and videos classify some of their content as adult. They
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.
