Web Control - Allied Telesis AR Series Technical Manual

Feature Overview

Web Control

Web Control is supported in version 5.4.5 or later.
AlliedWare Plus Web Control provides a new level of service for business productivity management,
compliance and web security. It offers an easy way to monitor and control the types of websites
viewed by employees. It stops staff members visiting inappropriate websites that:

Drain their productivity

Contain questionable content

Are bandwidth intensive and hence put a strain on resources

Pose potential security threats to the organization
Web Control provides dynamic URL coverage, assigning websites or pages into around 100
categories, and allowing or blocking website access in real-time.
Once a particular URL has been categorized, the result is cached in the device so that any
subsequent web requests with the same URL can be immediately processed according to the policy
in place.
The Web Control process uses Digital Arts' active rating system.

How Web Control works
Integrated with Digital Arts' Active Rating System (ARS), AlliedWare Plus Web Control provides
comprehensive and dynamic website coverage with high accuracy of categorization. AlliedWare
Plus™ Web Control is capable of accurately assigning millions of websites or pages into around 100
categories and allowing or blocking website access in real-time.
AlliedWare Plus Web Control provides the following features:

Categorizes a vast number of websites in multiple languages

Covers millions of the most relevant websites in around 100 categories

Supports multiple categorizations for a single website

Supports management and configuration of categories, rules and website categorization provider
AlliedWare Plus Web Control uses a website classifier engine and caching mechanism to filter HTTP
and HTTPS traffic.
When an HTTP request passes through the device, the associated TCP session transporting the
HTTP data is proxied. The embedded URL of the website is intercepted and sent to the website
classifier engine to retrieve the category the website belongs to.
