Dynamic Classification

Cyren’s GlobalView Web Filtering service allows network administrators to control the LAN client’s access to certain types of websites without specifying every URLs. The categorization will be based on Cyren’s database which holds more than 140,000,000 frequently-updated URLs with global-wide coverage.

Covering 64 Categories

GlobalView Web Content Filter provides 64 categories covering child protection, leisure, business, chatting, and computer-Internet, provide application such as parental control, regulatory compliance, employee productivity increase, bandwidth management, and more.

Improving Network Security

There are 8 security-related categories including spam sites, phishing, malware, and bots. These would help automatically filter out the web threats that you might not even be aware of.

Overview

DrayTek’s Web Content Filter (WCF) blocks undesirable web content based on the configuration in the router. Any web site browse request is compared with a URL Filtering database provided by Commtouch’s GlobalView WCF which is updated in real time through the Cloud.

GlobalView classifies all websites around the globe into 64 categories that can be selected to be either blocked or permitted and be applied to the required user groups. For example, children at home can be prevented from accessing adult sites, or employees in the workplace can be restricted from accessing unrelated social networking sites during work hours.

Since website contents are constantly changing, GlobalView URL Filter is also continuously being updated to ensure on-going accuracy and protection to users.

Reason to BlockExample
Potential threatsWebsites containing viruses, malware, phishing and zombies/bots, etc.
Anti-productivityUnproductive or unrelated sites for employees’ e.g. social networking.
Child protectionAdult material for children e.g. pornography, gambling.
IllegalityIllegal material downloading sites
Bandwidth RegulationUnrelated website traffic, e.g. movies, music, etc., that consume network bandwidth of the organisation.

Mechanism for Commtouch GlobalView URL Filtering (URLF)

  1. The DrayTek router receives a http request from a user.
  2. The router queries the GlobalView server to check the URL classification.
  3. The GlobalView URL engine built into the router checks its local cache for URL values; typically more than 99% of queries are locally resolved by the cache.
  4. If necessary, the GlobalView URLF engine queries the Commtouch Detection and Classification Centre for relevant updates.
  5. The router blocks, allows or strips content according to the class classification it receives from the GlobalView URLF engine and the configuration of the WCF.
