Membatasi Facebook, YouTube dengan draytek vigor
Salah satu fitur menarik menggunakan draytek vigor adalah kemampuan untuk melakukan filtering terhadap akses ke jaringan, atau dikenal dengan web Content filtering.
|The Vigor 2710 Series also features Web Content Filtering, allowing you to block web sites or content by keyword matching, content file type or by using DrayTek's new GlobalView site cetegorisation system (subject to subscription).|
DrayTek Web Filtering allows you to block web content in three main ways:
Features 1,3 and 4 above are included with the router. Feature 2 is included but requires an annual subscription to the external server which keeps a real-time contstantly updated database of web sites. More details of that later.
1. Keyword MatchingIn Keyword Matching you can specify a list of either banned (blacklist)) or permitted sites (whitelist). The DrayTek method is 'object' oriented, which means that you create lists of keywords or sites, can then group them and then apply them into specific user groups or time periods
Using a blacklist, all sites would be accessible by your users except those that match the keywords you specify. This would be useful, for example where there are specific sites known to be causing distuption or timewasting in your organsiation such as social networking or webmail. The example below would allow access to all sites except the ones listed:
2. Web Site Category (DrayTek GlobalView)DrayTek's GlobalView allows you to select specific categories of web site which your router will allow access to. For example, an office may wish to block access to social networking or other company-time wasting sites or a home user might want to block adult sites from their children
GlobalView covers 64 separate categories which you can select as blocked or permitted. Every time one of your users attempts to access a site, the router's automatically queries the central GlobalView server to ascertain its classification. This takes only milliseconds. If a site is blocked by GlobalView, according to the categories you have selected, instead of the requested web page, a warning message is displayed to the user (you can customise the message).
3. Digital Content TypeDrayTek's Content filtering allows you to specify particular data types or web content to be blocked by the router. The vigor is pre-set with many different content types or protocols. You can select any or all of them for blocking. There are infinite combinations but some examples of commonly blocked content are:
